Question 1: Formulas. We've learned how to write algebraic equations in the form of: mx + b = y. Convert these two sentences into algebraic equations using the above formula.

Sentence 1 : Scott is 2 years older than Donald who turns 12 on June 21st 2006. Write this sentence in the format of mx + b = y, then convert it into an expression which allows us to figure out the age of Scott.

Answer : 2 + b = y
2 + 11 = y
2 + 11 = 13

Sentence 2: Elizabeth has $200 in her savings account. She makes $40 every two weeks babysitting for her next door neighbours. If Elizabeth saves all of her money solve for how much money she will have in one year.

Answer : 40+200e=
40 +200(26)=5240

Question 2: Creation: You need to create two questions for your classmates that cover different concepts (ex: T-Charts, patterns, equations, graphs etc.) that you have learned in this unit on Algebra. You then need to show how to solve the questions. Your mark will be based upon the level of question’s difficulty, and the effort put into your answer.

Answer : I'll do this tomorrow because i dont know what to put !

Question 3: Reflection: You need to look back at the chart that we filled out during the first day of the unit. This is the chart where you coloured a topic red, yellow or green. You now need to pick one concept that you coloured yellow or red and reflect in words what new skill/idea that you have learned on this topic.

Answer : Same for this one !

Question 4: Preparing for the final exam: You need to think about the year that has past in mathematics and decide which topic is your weakest, and what you need to learn during class review in order to prepare yourself for the final exam. It is not enough to say fractions, instead pick your weakest area of fractions, say the subtraction of fractions, and give an example of what you don’t understand.

Answer : And same for this one !

I'll do this tomorrow !

Question 1: Formulas. We've learned how to write algebraic equations in the form of mx + b = y
Convert these two sentences into algebraic using the above formula.

m: change or coefficient
b: constant or start
y: solution

Sentence 1: Scott is 2 years older than Donald who turns 12 on June 21st 2006. Write this sentence in the format of mx + b = y, then convert it into an expression which allows us to figure out the age of Scott. Scott is 13 years old and Donald will be 12 years old.

2 + b = y

2 + 11 = y

2 + 11 = 13

Sentence 2: Elizabeth has $200 in her savings account. She makes $40 every two weeks babysitting for her next door neighbours. If Elizabeth saves all of her money solve for how much money she will have in one year? Elizabeth will have a total of $1160 in one year.

$40n + $200 = y

$40(24) + $200 = $1160

Question 2: Creation. You need to create two questions for your classmates that cover different concepts (ex: T-charts, patterns, equations, graphs etc.) that you have learned in this unit on Algebra. You then need to show how to solve the questions. Your mark will be based upon the lvl of question's difficulty, and the effort put into your answer.

Bobby has $500 dollars in his bank account and he earns $50 every month. His friend John has $250 in his bank account and he earns $75 every month. How much will Bobby and John have in their bank account in one year and who will have the most amount of money? Bobby will have a total of $1100 and John will have a total of $1150 and John will have $50 more than Bobby.

$50x + $500 = y

$50(12) + $500 = $1100

$75x + $250 = y

$75(12) + $250 = $1150

One day, Sandy and Lina decided to save money and buy a walkman for $150 and share it with each other since they were sisters. Sandy had $60 in her bank account and she would add $10 everyday for 10 days while Lina had $120 in her bank account but she would spend $10 everyday for herself for 10 days. On the 10th day, will Lina and Sandy have enough money to buy the $150 walkman and have leftover money? Or will they have to save more to buy a walkman? Sandy and Lina will have enough money in total to buy the $150 walkman and have $40 leftover.

Sandy: 10x + 60 = y

10(11) + 60 = 170

Lina: -10x + 120 = y

-10(10) + 120 = 20

Question 3: Reflection. You need to look back at the chart that we filled out during the first day of the unit. This is the chart where you coloured a topic red, yellow or green. You now need to pick one concept that you coloured yellow or red and reflect in words what new skill/idea that you have learned on this topic.

Can I use my words to create an algebraic formula?

I coloured this in red because I didn't know how to create a algebraic formula. So if I didn't know how to make one, I would probably not be able to make one from a T-Chart or use an algebraic formula to solve for an unknown. It was easier to make a formula when Mr.Reece had taught us how and it was helping me solve an unknown and make a formula by using a T-Chart.

Question 4: Preparing for the final exam. You need to think about the year that has past in mathematics and decide which topic is your weakest, and what you need to learn duriong class review in order to prepare yourself for the final exam. It is not enough to say fractions, instead pick your weakest area of fractions, say the subtraction or fractions, and give an example of what you don't understand.

My weakest topic is probably algebra. In algebra, there are always some questions that I can't figure out how to solve the unknown. But as Mr.Reece is teaching us, I am beginning to find it more easy little at a time and will be able to solve it. I also know that when the higher the grade i'm in, the harder the level of mathematics are and the harder the questions in algebra. (eaxample: -50x + 2o6 = y)

2006-06-05T16:38:00.000-05:00

In class today we looked through some of our worksheets in our duotang and answered the questions. We answered the questions because on the test, there are some similar questions.

Page 28:
18) Using the equation 2x+1=y, create a table of values where x equals 2, 3, 5, 7, and 8.

19)Complete the table

Page 32:
8)What does n equal in the diagram below?
4 diamonds(n)=32
(n)=32/4 n=8

9)What does n equal in the diagram below?

n/3=8x3
x3
n=24

Page 35:
2)Six friends are going to equally share a sum of money. Each friend will receive $9.76. Write an equation which shows the original sum of money.
n=(9.76)x6

3)Write an equation to show "sixty by a number equals three".
60/n=3

4)When a number is added to twelve, the sum is seventeen. Write this equation.
12+n=17

5)Express 4n=14
Four multipled by a number equals 14.

Page 25:
6)Using the table above, when did the temperature rise the most?

85-30=55 According to the table, the temperature rose the most between 0 to 5 minutes.
130-85=45
155-130=25
170-155=15

7)Predict the temperature of the oven at the 12 minute mark.
25/5=5 degrees celcius 130+5+5=140

8)What algebraic expression would explain the relationship between Bob's and Doug's pens?
B=Bob's pens D=Doug's pens
B=2D-2 B/2+1=D

9)a)How many pens would Doug have if Bob had 16 pens.
16/2+1=9
b)If Doug had 10 pens, how many would Bob have?
2(10)-2=18

Remember that the rule has to work out with all the possibilities or else it won't work.

Lastly, we watched a brain-pop video on solving equations.

Yesterday in class we learned about the Terms used in Algebra.

Variable: These are letters that represent numbers. They vary in that we substitute a variable for one or more unknowns

Constant: Their value never changes in an expression. A constant is another word for starting point.

Coefficient: These are the numbers that are teamed with the variable. A coefficient is another word for the change.

Next we reveiwed the answer for question #4 on the quis we took the other day.

Algebraic Equation: Jenny's money

Next we looked at the mathematical format for writing algebraic equations.

In class we've been doing: Start+change(variable)

In grade 8 and amd the other grades beyond that, we're going to use the Mathematical method:

The next scribe will be Melissa.

Question 1: What is the difference between an algerbraic expression and an equation (Hint: One contains this and the other doesn't)? Give an example of both an expression and an equation.

An algebraic expression is when you combine numbers, operatives, grouping symbols (such as brackets and parentheses) and/or free variables and bound variables. You get to choose the variable in an algebraic expression. An example of an algebraic expression is 20J / 5. In an algebraic equation is when you combine numbers, operatives, grouping symbols (such as brakets and parentheses) and/or free variables and bouund variables. In an equation the value of the variable is given. A example for an algebraic equation is 20J / 5 = 20. J equals 5.

Question 2: What is a variable and why do we use one in algebra?

A variable is a letter that replaces a number we are solving for. The variable stands for the unknown. We use a variable (a letter) in algebra so the equations we are solving do not become confusing. Example is we use numbers as variables instead of letters.
21 + 13 = 17 This equation doesn't make sense. Now here's the same equation except we use letters for the variable. 2A + 13 = 17. A eaquals 2. You multiply 2 by A which is 2. 2 x 2= 4. Your final equation would be 4 + 13 = 17.

Question 3: Solve for N.

I found that since 2 circles equals 1 square and a circle equals one, that a square equals 2. To solve the second question you need to figure out what a triangle equals on the first scale. I took away four circles (each square equals two circles), and it left me with five circles. Since there were five circles left the triangle equals five circles each. Then I needed to solve the N's. If each square equals 2 and each triangle equals f circles each which is 10. I added it up and got 22. that means you now have to divide 22 in half and you'd get 11. So N eqauls 11.

Question 4: Solve the following equations. Show all of the steps that are needed.

a.) 3n+4n+7=2n+12
7n+7=2n+127n-2n(+7-7)=2n-2n(+12-7)
5n=5
N=1

b) 8n-(4+9)=1
1 8(3)-(4+9)=
1124-13=11
N= 3

(c) (8-3)n+7n+8=
4n+405n+7n+8=
4n+405(4)+7(4)+8=
4(4)+4020+28+8=56
N= 4

Question 5: For this question you need to create a T-Chart and a graph to plot your data from this question onto.

You are having a race against your friend, except you are on foot and he is on his bike. Your both know that if you are on a bike you will be faster so your friend gives you a head start of 3 minutes. If you can run 400m per minute, and your friend can bike 700m per minute, who will be the first to make it to the finish line 2000m away?The runner will cross the finish line first in 5 minutes. The biker will cross the finish line second in 6 minutes

Growing post #3

2006-05-29T19:51:00.000-05:00

Question #1
In an algebraic expression we get to choose the value of the variable. example: 3+4n = "n" is the variable.
I an equation the value of the variable is already given. example: 3+4n = 19
Question #2
Variables are any letter ( a - z ) that represent numbers. In an algebraic equation you are solving what the variable represent. It already had a value in an equation. In an expression you choose what the variable represent like the example in question 1.

Question #3
First I took away four circles (each square equals two circles), and it left me with five circles. Since there were five circles left the triangle equals five circles. To solve the second question you need to figure out the value of the two Ns. First I added the squares and triangles together. The total of the squares and triangles and it was 22 circles. Then I divided the 22 circles by 2. The answer was 11. So each N equals 11 circles.
Question #4
a) 3n + 4n + 7 = 2n + 12
7n + 7 = 2n + 12 7n - 2n = 12 - 7 5n = 5 N = 5/5 n = 1
b) 8n - (4+9) = 11
8n - 13 = 11 8n = 13 + 11 8n = 24 n = 24 / 8 n = 3
c) (8-3)n + 7n + 8 = 4n + 40
5n + 7n + 8 = 4n + 40 12n + 8 = 4n + 40 12n - 4n = 40 - 8 8n = 32 n = 32/8 n = 4
Question #5
I'll do number five SOON !

Notes for the growing post

Qustion 4. you must sovle for N ie. n-10 or n-3 remember you will not get a fraction decided or negative number as your answer.

Qustion 5. you will need 2 T-charts for this question remember for your gragh the person on the bike doesn't go anywhere for the first 3 minunts.

The homework is to do page 30, 31, 32, and 33

examples for our homework if you don't get like # 10 on page 32

n divided by 3.5 = 7
then 3.5 times 3.5 will canceal it out
and then 7 times 3.5

then N = 24.5

At the beginning of class we did mental math. Next, our homework was checked which was the ' Solving Algebraic (Linear) Equations ' worksheet.

If you didn't get the homework, here's how you do some of the questions. If you can do these questions you shouldn't have any problems with the other ones.

17) 5A + 8 = 3A + 12
Step 1 - Since there are variables on both sides you the find smallest number which is 3A.
Step 2 - You then subtract 3A with its opposite which is -3A . Looks like this :Step 3 - 3A cancels . If you subtract on one side you must subtract from the other.Step 4 - You still have the 8 which we don't want. So we do the same thing we did with 3A. Subtract 8 from its opposite, remember if you subtract from one side you subtract on the other too.
Step 5 - Last thing you do is divide 2A to 4 and you'll get the answer. A = 2

Here's another equation that deals with brackets.

13) (4-2)A + 3 = 13
Step 1 - First of all, you do the brackets.
2A + 3 = 13
Step 2 - You then subtract 3 and 13 from 3. 3 because its the smaller than 13.
2A = 10
Step 3 - divide 2A to 10.
A = 5

* We'll be having a test on this unit later on next week.

The graph for homework: remember that the lines are the perimeter. It's the outside not inside. on question 1 Figure 1 it's not 5 lines. If you don't get counting the lines, heres a diagram to help you understand.Homework:
- growing post is due on May 29th
- graph worksheet due tomorrow

Press the "ctrl" key and the "f" key at the same time and enter *Week of MAY 23 - MAY 26* so you don't have to scroll down alot. Same goes for the *Week of MAY 29 - JUNE 03*. You can enlarge the pictures by clicking on them so you can get a clearer view.

-------------------Week of MAY 15 - MAY 20-------------------

Question #1: Solve all 3 parts of the problem below

Jack collects baseball cards. Jack has 180 baseball cards in his collection. At the end of each month Jack buys 25 baseball cards to add to his collection.

a)Create a T-Chart showing how many baseball cards Jack has at the end of the next 4 months.

b)Create an algebraic formula based upon the problem above
180 + 25m = total of cards
*(m=the number of months)

c)If Jack just turned 8 years old this month and Jack continues to buy the same amount of baseball cards each month, how many baseball cards will Jack have when he turns 12?
12 months x 4 years = 48 months
m= 48a
180 + 25(48) = 1380
Jack will have 1380 baseball cards when he turns 12.

Question #2: Use the chart to figure out the questions below.

*chart taken from Mr. Reece's post on what the questions are for this growing post.

Jackie is planning on having a pizza party with some of her friends. She is trying to figure out how many pizza’s to order. She knows that each pizza has six slices of pizza.

a)If Jackie thinks that there will be four people at the party (counting herself) how many pizza’s should she order?
There are 4 people at the party so if you look at the chart, for 4 people there are 12 slices.
12 slices/6 slices = 2 pizzas
Jackie should order 2 pizzas.

b)If two more people show up at the party how many more pizza’s does she need to order?
Based on the chart, for 6 people you need 18 slices of pizza.
18 slices/6 slices = 3 pizzas
Jackie should order 3 pizzas.

Question #3: Answer the question below based upon this information

Kathy has $20 in her savings account. Each month she adds another $15 to her savings account. In order to calculate how much money she will have in one year Kathy has created this algebraic formula: 20 + 15n = Savings amount

a) Calculate how much money Kathy will have in one year.
There are 12 months in one year.
n = 12 months
20 + 15(12) = 200

Kathy will have $200 by the end of the year.

b) Suppose Kathy counted wrong and she really has $25 in her account instead of $20. Change the algebraic formula to reflect this miscalculation.
All your changing is one number and you don't need to change anything else.
25 + 15n = Savings Amount

Question #4: Solve the following equations. Show all of the steps that are needed.

a) 3n + 4n + 7 = 2n + 12
3n + 4n - 2n = 12 - 7
7n - 2n = 5
5n = 5
n=5/5
n=1

check: 3(1) + 4(1) + 7 = 14
2(1) + 12 = 14

b) 8n – (4 + 9) = 11
8n - 13= 11
8n = 11+13
8n = 24
n= 24/8
n = 3

check: 8(3) - 13 = 11
24 - 13 = 11

c) (8 – 3 )n + 7n + 8 = 4n + 40
5n + 7n + 8 = 4n + 40
5n + 7n - 4n = 40 - 8
12n - 4n = 32
8n = 32
n = 32/8
n=4

check: 5(4) + 7(4) + 8 = 4(4) + 40
20 + 28 + 8 = 56
16 + 40 = 56

Question #1: What is the difference between an algebraic expression and an algebraic equation (hint: One contains this and the other doesn't)? Give an example of both an algebraic expression and an equation.

In an algebraic expression you get to choose what the variable is.
Example: 3 + 4n =
Let's exchange "n" for a 3.
3 + 4(3) = 15
In an algebraic expression you can never go wrong, unless you're dealing with a word problem and it's asking you to put a specific number in.

In an algebraic equation you have to find out what the value of the variable is.
Example: 3 + 4n = 19
n=4

Question #2: What is a variable and why do we use it in algebra?

In an algebraic expression, a variable is the part of the expression in which you can exchange it for a number in order to find out what the answer to a question is. Like if your trying to solve how many minutes are in a certain amount of hours, you can exchange the variable and replace it for the amount of hours.

In an algebraic equation, a variable is the part of the equation we are trying to solve. For example, suppose this was the question you were trying to solve 4n = 32. The variable is the letter "n".

In algebra we use variables because we don't know the value, and we want to find what it is. We also use variables to do all the algebraic manipulation (like simplifying an expression) without using actual numbers, to save work.

Question #3: Solve for N

For question 3, you have to do the first part first. Solve the value for the triangle first.

To do this, it's easier to write it out as an equation. 1 square equals 2 circles and 2 circles equals the number 1. Lets write the triangle as "n". There are 2 squares, and that equals 2 circles. The equation is 4 + n = 9. Subtract 4 from 9 and that equals 5. Now we know that n=9. Now that we know what the triangle is, we have to solve the second part of the question.

Again, it is easier to write is as an equation. This time the equation is n + n = 12 + 18. Add 12 and 18 together and you get 30. Rewrite the equation and it becomes: n + n =30. Since there are 2 n's, all you need to do is divide 30 in half. Therefore, n = 15.

Question #4: Solve the following equations. Show all the steps that are needed.

*note: for the next questions 4a, b, and c, in the diagram, S= step and A= answer.

a) 3n + 4n + 7 = 2n + 12

b) 8n - (4 + 9) = 11

c) (8 - 3)n + 7n + 8 = 4n + 40

Question #5: For this question you need to create a T-Chart and a graph to plot your data from this question onto.

You have a race against your friend, except your on foot and he is on his bike. You both know that if you are on a bike you will be faster so you will be faster so your friend gives you a head start of 3 minutes. If you can run 400m per minute, and your friend can bike 700m per minute, who will be the first to make it to the finish line 2000m away?

-------------------*Week of MAY 29 - JUNE 03*-------------------

Question 1: Formulas. We’ve learned how to write algebraic equations in the form of: mx + b = y. Convert these two sentences into algebraic equations using the above formula.

Sentence 1: Scott is 2 years older than Donald who turns 12 on June 21^st 2006. Write this sentence in the format of mx + b = y, then convert it into an expression which allows us to figure out the age of Scott.

There aren't any variables, so the sentence/expression/whatever is:
11 + 2 = Scott's age

If she makes $40 every 2 weeks, then that means she makes $20 per week (i divided 40 in half).

365 / 7 = about 52 weeks
200 + 20 x 52 = w
w = amount of money in 1 year.

Question 2: Creation: You need to create two questions for your classmates that cover different concepts (ex: T-Charts, patterns, equations, graphs etc.) that you have learned in this unit on Algebra. You then need to show how to solve the questions. Your mark will be based upon the level of question’s difficulty, and the effort put into your answer.

My Question #1: A girl named Mika started a farm one day. If her farm can only take 992 animals, how long will it be till the farm is all full with 992 or more animals (the information is on the t-chart below, the answer has no decimals)? Look at the t-chart. Notice that it only goes up to the 6^th day and that it doesn't go up to 992 animals. Your task is to use the information below to create an expressions and then create an equation and solve it to find out long it will be till the farm is full.

ANSWER: To solve this, you have to think how the person who made this problem up (me) got the y value (the # of animals) and how it is related to the x value (the day). If I didn't know how to solve this, I would try all sorts of things. One thing I would do is to think what number times the x value would equal the y value. I started noticing that if you multiply the number you are on by the number after it, it gives you the y value. So the expression is: (D + 1) D = A.

The thing that is easy now is to create the equation. All you have to do is plug in 992 into the expression. So now it becomes: (D+1) D = 992. You could answer it using the t-chart and extend it, but if you're lazy like me then you would try to do trial and error. For some odd reason I picked the number 31 and it was the answer. So D = 31.

My Question #2: Use the graph below to answer this question: Rico and Rico are brother and sister. They each own a shop. What is the
difference between the highest shop profit Rico's shop had and the lowest shop profit Rica's shop had?

ANSWER: According to the graph, the highest shop profit Rico had was $5 mil. and the lowest shop profit Rica had was 1 mil. So the answer would be $4 mil. because $5 mil. - $4 mil. = 1 mil.

Question 3: Reflection: You need to look back at the chart that we filled out during the first day of the unit. This is the chart where you coloured a topic red, yellow or green. You now need to pick one concept that you coloured yellow or red and reflect in words what new skill/idea that you have learned on this topic.

I can now use a t-chart in helping me to create an algebraic formula because I think my analysis skills have developed more. That's good because I think I can see the pattern going on in the t-chart and create a formula out of that information.

Question 4: Preparing for the final exam: You need to think about the year that has past in mathematics and decide which topic is your weakest, and what you need to learn during class review in order to prepare yourself for the final exam. It is not enough to say fractions, instead pick your weakest area of fractions, say the subtraction of fractions, and give an example of what you don’t understand.

The topic that I am the weakest in would have to be doing operations with fractions. For example in the diagram below,I don't get how to questions like those. I think we should do a few worksheets on those and some of the other things people had trouble with.

GROWING POST #2 - MAY 15th - 23rd

Question #1

A)

B) 180 + 25(n)
180 + 25(1) = 205
180 + 25(2) = 230
180 + 25(3) = 255
180 + 25(4) = 280

C) 8 - 12 = 4(years)
1 year is equal to 12 months. So 12 x 4 = 48
algebraic formula
180 + 25(48) = 1380
Jack will have 1380 cards when he turns 12

Question #2

A) 12 slices of pizza
solution: 12/6 = 2 (6 is the amount of slices in 1 whole pizza)
Jackie should order 2 pizzas.

B) 18 slices of pizza
solution: 18/6 = 3 (6 is the amount of slices in 1 whole pizza)
Jackie should order 3 pizzas.

Question #3

A) 20 + 15n = savings amount
(start + change variable = answer)
formula
20 + 15(12) = 200
Kathy will make 200 dollars in 1 year.

B) 25 + 15n = savings amount
25 + 15(12) = 205

Question #4

a) 3n + 4n + 7 = 2n + 12
solution
3n + 4n - 2n = 12 - 7
7n - 2n = 12 - 7
5n = 5
5 divided by 5 = 1
n = 1
checking: 3(1) + 4(1) - 7 = 2(1) + 12 } 14 = 14

b) 8n - (4+9) = 11
solution
8n - 13 = 11
8n = 11 + 13
8n = 24
24/8 = 3

c) (8 - 3) n + 7n + 8 = 4n + 40
solution
5n + 7n + 8 = 4n + 40
5n + 7n - 4n = 40 - 8
12n - 4n = 32
8n = 32
8/32 = 4
n= 4
checking: (8 - 3)(4) + 7(4) + 8 = 4(4) + 40} 56 = 56

GROWING POST #3 - MAY 23rd - 29

Question #1

An algebraic expression is an expression when we get to choose the value of the variable.
example: 5 + 6v = (v for variable)
- exchange " v " to 5 (v=5)
- 5 + 6(5) = 35
An algebraic equation is when the value of the variable is given.
example: 5 + 6v = 35
- v=5
The difference between them are about their variables. The algebraic equation gives the variable and the expression lets you choose the variable.

Question #2

In an algebraic expression, a variable is the number you can change. It looks like this : start + change(variable)<-- this is what you can change.

In an algebraic equation, a variable is the number you need to find out. Like this: 3 + 4n = 19
the answer is n=4 .

Basically, a variable is a symbol used to represent any number.

We use variables in algebra to represent an unknown number. Whether we know the value or not, variables help you solve things faster.

Question #3

This diagram tells me that the triangle is worth 5. I got that by first, finding the value of the squares and circles. The blue arrow points to 2 squares and 4 circles. The orange arrow points to 4 1/2 squares and 9 circles. Last, I subtracted 9 from 4 . 9 - 4 = 5

This diagram tells me that n = 11. This is how i found out: First of all you need to do the first problem to do this one. On the last diagram, it showed me that a triangle equals 5. I first found out how many circles were equal to the blue squares. ( I split the triangles and squares to make it more non-complicated; thats that red line dividing them ) . So 6 squares equal 12 circles. Now the trianlge part. I know that 1 triangle is worth 5 (circles) , and there are 2 triangles. 5 x 2 = 10. I then added 12 and 10 which gave me 22. To find out what n was worth i just divided 22 by two, since there were 2 triangles.

Question #4 ( I did this question on the last growing post)

Question #5

Sentence 2 : Elizabeth has $200 in her savings account. She makes $40 every two weeks babysitting for her next door neighbours. If Elizabeth saves all of her money solve for how much money she will have in one year?

Answer :

- first you need to know how many weeks are in a year. 365/7 = about 52
- find out how many 2 weeks are in a year 365/14 = 26
- 200 + 40(26) = 1240

Question 2: Creation: You need to create two questions for your classmates that cover different concepts (ex: T-Charts, patterns, equations, graphs etc.) that you have learned in this unit on Algebra.

My Question #1 - Jen has 5 marbles. She makes another 5 marbles every week. if Jen collects all her marbles in 1 year, how many marbles would she have ? Create a T-chart for the first 3 weeks then show week number 20, 40, and weeks in a year. Make an equation with the format mx + b =y and a graph .

Answer : T- chart :

There are about 52 weeks in a year. I found that out by diving 7 by 365.

equation :
mx + b = y
5x + b = y
5w(weeks) + 5 = y

Graph:

Jen will have 265 marbles in 1 year.

My Question #2 - Gina gets $200 on her birthday every year. This year she got $210. Gina plans to buy a laptop in 4 years ( not including this year) which will cost $1,000. Will she have enough money to buy her laptop? how much will she have? Make a T-chart, graph and an equation to solve this porblem.

Answer :

equation:
- 210 + 200y = solution
- 210 + 200(4) = 1010

- 200x4 = 800 + 210 = $1010
Gina will end up with $1010 in 4 years. She will have enough money to buy her laptop and have an extra $10.

#1. Rotation Symmetry means if you can rotate (or turn) a figure around a center point by fewer than 360° and the figure appears unchanged.Reflection symmetry means that a shape or figure will have a mirrored image of the shape which makes it look unique but when the shape is flipped or they will look the same.

QUESTION #1: What is meant by the terms "Rotation Symmetry" and "Reflection Symmetry"? How does this relate to pentominoes? Explain these terms so that anyone who reads your post understands what you mean.

my ANSWER: Rotation symmetry is when you can rotate (or turn) a figure around a center point by fewer than 360° and the figure appears unchanged.Reflection symmetry happens if a figure or object looks the same after being reflected in a mirror. This relates to pentominoes because there are only 12 unique ones. By unique I mean that there are no reflectional or rotational symmetries. Because if you do an L type shape then if you rotate it around then it won't be unique. It'll still be the same shape but just at a different way around.

1. Rotation symmetry means to turn an object around, every rotation has a center and an angle. Reflection symmetry means to make an object appear as its mirror image. This relates to pentominoes because if you rotate or reflect the pentomino, it doesn't count as a different one.

#1 Rotation symmetry means when a figure appears to be the same after you rotate or turn it. Reflection symmetry means when a figure appears to be the same after you flip it. Rotation symmetry and reflectoin symmetry relates to pentominioes by describing or determining if a pentominoe is unique or not.

Question #1: What is meant by the terms "Rotation Symmetry" and "Reflection Symmetry"? How does this relate to pentominoes? Explain these terms so that anyone who reads your post understands what you mean.

A Reflection Symmetry means when the axis of symmetry of a two-dimensional figure is a line such that, if a perpendicular is constructed, any two points lying on the perpendicular at equal distances from the axis of symmetry are identical

A Rotation Symmetry is symmetry with respect to rotations, like isometries that preserve orientation. For instance, you can take any point on any shape, and rotate on the point, and it'll still be the same shape, thus preserving the orientation.

These two terms relate to pentominoes because you can rotate(like in rotational symmetry) and flip (like in refectional symmetry) .

Question #2: Create a pattern. You must represent this pattern both pictorially (i.e. with a picture or diagram) and with numbers. You must show the first 4 steps of your pattern.

Today in class we took notes on describing patterns and algebraic formulas. For describing patterns the steps to make a pattern are 1- Describe the first shape(size, quantitiy and shape) 2- change between each shape/step (increase/decrease, size of change). The pattern we made started with 3 triangles and everytime you have to add one more triangle. We also made a t-chart. This is what we learnt on algebraic formula's. An algebraic formula for any changing pattern needs the following components.
1-starting point
2-change from one step to the next
3-A variable that represents any possible step in the pattern.
A variable is an unknown quantity that we are trying to solve for.

this is three points that you would write down on a graph like x and y aswell has what you are looking for on the graph (5 -3).

the last part of class we spent a graph on the coordinate planes and found out the shpes mr. Reece gave us on a sheet.

We had to follow specific instructions, to create our shape. The directions were
SHAPE #2:
E. Start at (-11, 13)
F. Down 1, Right 7
G. Down 4, Left 2
H. Up 1, Left 7
It makes a parallelogram:

today in class we corrected the little quiz that Mr. reece gave us. We found out how to get the area of irregular shapes. First you must break them into smaller easier shapes then do the various steps for the shapes. We also started working on finding coordinates in a grid. On a grid the vertical line is labeled as Y, while the horizontal line is labeled as X. You also label every point as the letter or symbol given. On the grid we had to find these positions, A(8,2)B(-4,3)C(2,-5)D(5,4)E(-7,-1)F(4,7)G(-3,-9)H(-2,-3)I(-3,2)
That's all!

After we finished measuring 8 circles. We divide the Circumference by the Diameter
Example

Circle 1b 3b 7a 8a

Diameter 12cm 17cm 12cm 13cm

Radius 6cm 85cm 6cm 6.5cm

Circumference 37cm 55cm 39cm 44cm

Circumference/Diameter 3.08cm 3.24cm 3.25cm 3.38cm

What dose Circumference divides by Diameter give you Pi = π, 3.14 is π

π is a arashion number

Here is the formula for π

Diammeter * π = Circumference
Circomference ÷ π = Diammeter
( Radius *2) * π = Circumference

Diammeter = 2 Radius
Radius = ½ Dmmeter

After we look at the smrat borad a whach a cilp of th e Brain pop on π

Today in class we have learned about the Elements of a circle.

Elements of a circle

The elements of a circle include :
circle - The dot
diameter- Measures the width of a circle. it has to pass through the centre.
Radius- Starts at the centre and goes to 1 edge.
Circumfrence- It's the outside edge of the circle.

We were also using string and lid caps from butter container to try to find the Radius,Diameter,circumference and the circumference/diameter for the string.
Here's a sample of the table we used:

Today in class we found out how to determine the area of a polygon. We were given a piece of paper with dots. You had to make a rectangle by using 18 or 24 line segments (mr.reece told us if we had to do 18 or 24 lines).
Heres an example of a rectangle by using 18 line segments :

to find the perimeter you must add all the sides.

After making the perimeter of the shape we had to find out the area, here's what we did next :

We tried to find out how many squares could fit in the shape. You can determine the area by multiplying the width and height. Heres the formula (height x width = area) . Which, in this case is (3x6=18).

<- This was the result.

Mr.Reece also mentioned about a square, a square can be a rectangle.

* remember, all this will be on our final exam!

Homework :
Your corrections for the quiz we did on March,23. Due on Friday.

if you have any bonus worksheets such as sudokus, you hand them in on Friday as well.

April 3 2006

beginning of class:
Today in class Mr. Reece gave us this notebook thats called mental math. well thats what i think it said. But in it, it had lots of questions on what we've learned and what we are going to learn. Well on it Mr. Reece will give us a time to finish one page in the book. This shows what you have remembered the past few lessons we've had.

second part of class:
In the second part of class all of us have learned how to determine the perimeter of a polygon.

How To Determine the Perimeter of a Polygon :
add all the sides together.

for ex. add 1+2+3+4+5= the perimeter.

^^^^^^pretend that number ones side is 3 cm and two is 7 cm three is 3 cm four is 4 cm and five is 6 cm. soo then add them up. 3cm + 7cm + 3cm + 4cm + 6cm = 23 cm. and thats how you could determine the perimeter of a polygon.

the end of class:
uhm i think that we were just working on something. SORRY MR. REECE!! dont think i was paying attention.. ! :'(

REMINDER

a polygon is a CLOSED shape
it has to have AT LEAST 3 sides
and it has to have at lease 3 angles

sorry im late on being the scribe. well yeah mhm rozette mallari is the next scribe.

Sorry I couldn't make the post yesterday! My internet got cut... To make up for that I'll do the post for yesterday and today!!!

MARCH.23.2006
At the beginning of yesterdays class, we reviewed what we learned 2 days ago.

We tried to see that if you add how many triangles are in a shape, they make the total degrees of that shape. We did this by continuing the table we started 2 days ago....
Here's an example of the table:

As you can see there are some flaws to this rule... We figured it out today...

After a few minutes we did a quiz.

When everyone was done, we watched a video on the smartboard about measuring angles. It reviewed about how much some angles measured:

Acute - under 90º <>

-----------------------------------------------------------------------------

MARCH.24.2006

Today at math we finished off the table for the greedy triangle. My table looked like this:

We figured out the formula to solve the sum of all the angles in a shape without having to use a protractor to measure them all.

n=amount of sides in the shape
(n-2) x 180º=

I'll give you an example:
[] <---pretend that's and octagon
This shape has 8 sides so n=8
(n - 2) x 180º = (8-2) x 180º = 6 x 180º = 1080º
Therefore, the sum of the all the angles in that shape equal 1080º. If you're confused about anything I have written so far...Leave a comment to this post.

Near the end of class, Mr. Reece introduced us to a Japanese mind game called SUDOKU. If you want to know more, go to this site: http://en.wikipedia.org/wiki/Sudoku.
That's all we did in class today.

Today in class we learned about triangles

What Do we know about triangles?

We know there are 3 sides in a triangle.

There is 3 angles in a triangle.

It equals to 180 degrees.

These are three triangles we learned in class

What kind of triangle has 3 equal sides?

An Equilateral triangle has three equal sides.

What kind of triangle has 2 equal sides?

An Isosceles trangle has 2 equal sides.

What kind of triangle has no equal sides?

A Scalene has no equal sides

REGULAR VERSUS IRREGULAR POLYGONS

What is a regular Polygon?

If all the sides and all the angles of a polygon are equal the polygon is said to be regular.

What is a irregular polygon?

Irregular polygons have sides of differing lengths and angles of differing measure.

After all that learning we watched a short film from Brain Pop. It was all about the angles and triangles. After the short film we had a quiz out of ten.

Remeber there's homework due tomarrow 10.6.

THE NEXT SCRIBE IS MELISSA

Thank You...

2006-03-21T08:04:00.000-06:00

In Class we talked about Polygons. We figured out what a polygon is.

A polygon has 3 or more sides.
Multiple Angles.
and is a closed figure or shape.

We also found out that you can't make a polygon with 2 sides.
A circle isn't a polygon, because it has no angles.
And polygons can only have straight lines.

In class we worked on Triangles too.
A triangle has 3 sides. You should know already...
All sides are the same .
It has 3 different size sets.
and 2 sides are the same.

Hello Classmates :)
Today in class we did lots of intresting things and learned new things like "What makes a angle ?" Answer: A measure in degress of the Rotation of one line from another line at the Vertex.
We got a 2 sheets from Mr.Reece called "Angles Worksheet" One sheet where it has shapes like Square, Triangle, Rectangle, Other triangles and more. You had to put it in the table when it had a shape in it. Acute J, K, L, N Obtuse A,M Right, B,C,D Straight there are no angles, Reflex there is no angle too, None F,E,G,I,O,P,H.
(#2) Question: Explain why you placed the shapes where you did. What is your Rule? Rule: When measuring shapes we measures inside the angle.
(#3) Question: Draw one other shape and call it Q. Place it in your table. Explain why you placed it where you did.
Answer: I drew a 14 shaped star and put a Q. in it. The definition I put was It is an acute angle because every angle is less than 90*
We talked about the Vertex and what it means. For Example an Acute angle <> there are two angles that meet together and it is called a Vertex.

2006-03-06T22:53:00.000-06:00

Beginning of the class we reviewed the five different angles we learned on Thursday. Here are the types of angles:
-Acute Angle: Any angle that measure between 0-90 degrees.
-Right Angle: Any angle that is exactly 90 degrees.
-Obtuse Angle: Any angle that is greater than 90 degrees and less than 180 degrees.
-Straight Angle: Any angle that is exactly 180 degrees.
-Reflex Angle: Any angle that is greater than 180 and less than 360 degrees.

After we reviewed that, we looked at geometric terms. Here are the terms:
Point: A geometric element that indicates position, but has no size.
(You can’t measure it)
Example: (Point is written as “A”)

Line: Are a set of points in a straight line. They extend in both directions.
Example:

(Line is written as “ ”) (Two arrows)

Ray: A set of points that form a straight line. A ray starts at a point and extends forever in one direction.
Example: (Ray is written as “ ”) (one arrow)

Line Segment: Part of a line , but it has to endpoints.
Example: (Line is written as “ ”) (no arrows)

After that, we did this diagram. In the diagram below find all the following:
All 3 lines, 3 line segments, 6 rays and 3 points.

Lines:

Line Segments:

Rays:

Angles: Angles are formed with two rays or lines that meet at a common point. This endpoint is called the vertex.

Today in class we learned how to calculate the average measurement for your percent model. There are 3 steps to do it.

Step 1
Add together your percentages and divide it with the number of group members.

Example:
24%+22%+26%=72 72/3=24%

Step 2
Convert the average percentage into a decimal.

Example:
percent/100
24%/100=7.2

Step 3
Multiply your model's height by the decimal from step 2.

Example:
model height=25
25 x 0.24=6

For your percent model you might want to use toothpicks, popsicle sticks, straws, and anything else you can think of.

We learn about more on percentages today we did personal percentages
what it is that we had to get a partner and you have to measure our body parts like

Arm span
wrist to elbow
foot
hand
baby finger
head circumference
head length
shoulder width
shoulder to fingertip
waist to knee

we had to measure all these body part with a partner and we also did this

step 1

we had to divide measurement of the body parts by your overall height
Examaple
height = 165cm
foot = 24cm
24/165cm = 0.1454

step 2

multiply your answer from step 1 by 100
Examaple
0.145*100 = 14.54% or 15%

this all we did for today the next scribe iiiiiiiiiiiiiiiiissssssssssss

Today Mr. Reece talked about body percentages. To find out the percentages of a body part
you divide the measure of the body part by your height. Then multiply the decimal by 100 and you'll get the answer.

e.g

Mr. Reece's height is 165 cm. His arm span is also 165cm.
Nom you go 165cm divided by 165cm=1 multiply by 100 gives you 100%
That's how you find out body percentages.

Today we did some Directions worksheets that has to do with reading the directions first. We also did some Group Work worksheets that we had to do with our class groups.

Here are some examples:

Brian is trying to guess a 2-digit number. So far he knows that the tens' digit os greater than 6, and the ones' digit is odd. He also knows that the two digits are different. How many possibilities are there?

At Maverick Middle School, each student must take 3 of these 4 classes: music, art, drama, or keyboarding. How many different combinations do students have from which to choose?
