Combining Like Terms

Good morning, students!  Today, you will be practicing how to combine like terms.

Vocabulary you need to know:

constant: any number (ex: 3, 5, 7, 3.14, 1/2, etc...)

variable: any letter (x, y, m, z, etc...)

coefficient: the number in front of a variable in a term (5x, 6y, 14c, etc...)

term: a number times a letter (3x, -5y, 1/2z, etc...)

LIKE TERMS are terms that have the same variable raised to the same power (same exponent).

Example 1:

7x

x

-2x

These are all like terms because the variables are all x

Example 2:

(1/3)xy2

-2xy2

6xy2

These are all like terms because the variables are all xy²

Read through this tutorial FIRST:

Then, play these game to practice finding like terms:

One and Two Step Equations Review

Good morning, students!  Today we will be reviewing one and two step equations.  You will have a TWO STEP EQUATION ASSESSMENT on Friday!

Start by doing a quick math warm-up:
Choose your workout type and time: 2 minutes to 5 minutes

If you finish, you may visit any other site from my blog.  Good luck and Happy Learning!

Homework: Do the EVENS (2, 4, 6, etc...) or ODDS (1, 3, 5, etc...) on the EQUATIONS WORKSHEET.

Solving 2-step Equations

Good morning, students!  Today, we will be solving two-step equations.

Remember, equations are all about balance.  You have to do the same thing to both sides of your equation.  Both sides of the equation must be EQUAL or the same.

1. How to solve 2-step equations!  
Check out this explanation online about how to solve two-step equations:
http://www.coolmath.com/algebra/06-solving-equations/04-solving-equations-part3-01.htm


2. Keep it balanced!  
Here is a great way to model what those algebraic equations really mean.  You can choose one or two step equations depending on what you want to practice.  You can solve problems step by step or practice on your own!

Review: Positive & Negative Integers and One-Step Equations

Students, you will be having a test tomorrow.  You will be tested on one-step algebraic equations.  Make sure that you know your rules for adding/subtracting and multiplying/dividing positive and negative numbers.

Also, remember your OPPOSITES!  
1. The opposite of adding is...?
2. The opposite of multiplying is...?
3. The opposite of subtracting is...?
4. The opposite of dividing is...?
