7th grade homework for Friday September 28th, 2012

Remember when using formulas you need to read carefully what you are being asked.
For exercises 11 and 12, you need to find the area of each figure. Remember that the are of a rectangle is length times width, and the area of a square is side-squared.

Ex. 11, 12 p. 83 and Ex. 27p.84

Find the area of each figure:
11) Recangle: Length = 5in; Width = 2.5 in
12) Square: Side = 0.5cm

27)The circumference C of a circle can be found using the formula C=2Πr, where r represents the radius of the circle. What should Olivia do to write a formula to find the radius of a circle?

Remember that homework is meant to be done on a separate piece of paper.
Also, tomorrow we have an open book quiz. Just because it's open book don't forget to study, you DO need to study.

Have a great afternoon!

6th and 7th grade Homework for Thursday September 27th, 2012

6th grade:
Remember we must follow PEMDAS:

Exercises 4, 5, 14 and 15 page 50

Use the order of operations to fill in the blanks:
4) 4 x 5 + 7 = ____ + 7 = ____
5) 20 - 2 x 8 = ____ + 16 = _____

Find the value of each expression:
14) -12 ÷ 6 - (1 + 4)
15) 48 ÷ (-4 x 3) + 2

7th grade:

Our homework for tomorrow has to do with formulas. Tomorrow we will  have class, since your field trip has been cancelled and moved to Oct. 9th.

Remember that whenever we are working with formulas we need to see what we are being asked to know if we are going to have to isolate the variable or simply substitute and solve.

For exercises 21 and 22 you will need to isolate the variables asked and then substitute to solve.

Best of luck! See you all tomorrow!

Exercises 21, 22 and 24 p.84

Use the formula d = rt to find the following:
21) r for d = 12mi and t = 0.5h
22) t for d = 120km and r = 45 km/h

24) How is transforming a formula similar to solving an equation with just one variable? How is it different?

6th grade Topics for the Monthtly Test tomorrow Thursday Sept 20, 2012

Good afternoon 6th graders!
I apologize for the delay on the topics, I didnt have internet until a couple of minutes ago :(

The topics for tomorrow's test are:
- Add, subtract, multiply and divide decimals.
- Compare and order integers.
- Add, subtract, multiply and divide integers.

Remember to review vocabulary words such as: dividend, divisor, quotient, sum, difference, absolute value, integers, etc.

Make sure you practice so you feel confident and relaxed tomorrow.

See you all tomorrow!
Best of luck to you all!

6th and 7th grade homework for tomorrow Wednesday September 19th, 2012

6th graders:
Multiplying and Dividing integers:

Remember that whenever I have the same sign while multiplying and dividing, my answer will always be positive, and whenever I have different signs, my answer will always be negative:

Your homework for tomorrow is to determine whether your answer will be positive or negative, and then give an example of each:

a) positive ÷ positive =
b) negative x positive =
c) positive x positive =
d) negative ÷ negative =
e) negative ÷ positive =
f) positive x positive =
g) positive ÷ negative =
h) negative x negative =

Remember that all homework must be turned in during homeroom period, and it must be on a separate paper.

Have a great afternoon!

7th graders:

Hello all!
Yesterday we explained two different ways to add and subtract fractions. The first method (first example shown here) is working with the LCD (Least Common Denominator), as for the second method, it is working with the GCF at the end to simplify. Remember the cute butterfly?
                                       

The exercises for tomorrow are:

Ex. 1 - 3, 18, 19 p. 68
Find the LCD for each pair of fractions:
1) 1/2, 1/10
2) 1/3, 1/5
3) 1/4 + 1/14

Use a common denominator to find each sum or difference:
18) 2/15 - 1/10
19) 3/10 - 11/15

Ex. 31, 32 p. 69
Solve each equation for x when a = 1/2, b = 1/3, and c = 1/4. Write each answer in simplest form:
31) a + x = 3
32) 2 1/6 + x = -b

Remember you must show your work and that all homework must be turned in during homeroom period and on a separate paper.

Have a great afternoon!

7th grade homework for tomorrow Wednesday September 12th, 2012

7th graders
Remember that when solving an equation, the idea is to isolate (leave completely alone) the variable. In order for you to do so, you must work with the inverse operation at all times. Also, please remember that homework is meant to be done on a separate paper.

Here is the homework for tomorrow, see you all tomorrow!

1.) When is a value a solution to an equation?

Which property of equality does each equation illustrate?
2.) 24/4 = 8(3)
3.) 36 + (-10) = 4(9) + (-10)
4.) 8(-7) = (-56/-7)(-7)
5.) -5(6) - 13 = -30 - 13

For each equation, find whether -5 is a solution:
6.) 25v = -5
7.) 15/m = -3
8.) 10 = -2t
9.) -5p = 25
10.)7 = 35/w
11.) -45/z = -9

6th homework for tomorrow Wednesday September 12th, 2012

6th graders
Your homework for tomorrow will be about adding integers.

Remember the rules:

* Whenever you are adding integers with the same sign, the sum (answer) will continue having the same sign and you will add the absolute value of your addends. For example:
-2 + (-8) = -10 and 4 + 5 = 9

* Whenever you are adding integers with different signs, the sum will have the sign of your addend with the greatest absolute value, and you will subtract your absolute values. For example:
-6 + 11 = 5 and 9 + (-18) = -9

Using the number line:


Exercises for tomorrow:
Solve:
a) -2 + (-3)
b) -16 + 8
c) 9 + (-26)
d)-16 + (-43)
e) -9 + 3

Remember that homework is meant to be done on a separate paper.

Have a great afternoon!

6th grade homework for Thursday September 6th, 2012

Quick review of today's class:

What are integers? Integers are the set of positive whole numbers, their opposites, and zero.

Opposite integers: Two numbers that are the same distance from 0 on a number line, but in opposite directions.

Absolute value: is the distance of the number from 0 on a number line. For example: to find the absolute value of -3, count the units from 0 until you reach -3.

Also, to help yourself compare and order integers you may use a number line as a guide.

Below you will find the homework for tomorrow.

Have a great afternoon!


Word problems 43 and 44 on page 33.

43) Scores in a golf tournament are reported by the number of strokes each player is above or below par. The scores for five players are -12, +2, -7, +4, and -3. Order the scores from the lowest under par to the greatest over par.
*Which score is farthest to the left on a number line?
*Which score is the next-farthest to the left?

44) A friend does not know how to order integers. Explain how to order 12, -4, and -5 from least to greatest.
