Week of February 24th..
This week we will be beginning Chapter 7 Equations. In this chapter, your child will be learning how to write and solve addition, subtraction, multiplication, and division equations. They will then use those skills to solve two-step equations. Please review the key vocabulary words and activities that will be sent home on the "Family Letter" this week.

Week of February 18th..
On Friday, February 21st, the students will have their Chapter 6 tests on vocabulary and Expressions. All vocabulary words are located throughout Chapter 6 in your child's Math book. Your child also created a glossary to use as a quick reference as well. The students will be assessed on writing and evaluating mathematical expressions and will need to apply some properties of mathematics.
Please keep in mind, tests make up 45% of your child's marking period average.

Week of February 10th...
We are nearing the end of Chapter 6. The students will be using properties to simplify expressions.
Are all like terms because the variables are all xy2
Combine like terms:
Like Terms
"Like terms" are terms whose variables are the same.
In other words, terms that are "like" each other.
Note: the coefficients (the numbers you multiply by, such as "5" in 5x) can be different.
Example:
| 7x | x | -2x |
Are all like terms because the variables are all x
Example:
| −2xy2 | 6xy2 | xy2/2 |
Unlike Terms
If they are not like terms, they are called "Unlike Terms":
Example: These are all Unlike Terms because the variables and/or their exponents are different:
| 2x | 2x2 | 2y | 2xy |
Combining Like Terms
You can add like terms together to make one term:
Example: 7x + x
They are both like terms, so you can just add them:
7x + x = 8x
By the way ... why don't we write "1x" ?
It is just easier to write x. Imagine adding eggs:
7 eggs plus 1 egg is 8 eggs
is written 7 eggs + egg = 8 eggs
is written 7 eggs + egg = 8 eggs
Example: 4x3 + 3x2 − 7 − x2 + 2
Some of the terms are like terms.Combine like terms:
(4x3) + (3x2 − x2) + (2 − 7)
Then add like terms:
4x3 + 2x2 − 5
