# Ch 1: Common Core Math Grade 7 - Expressions & Equations: Algebraic Expressions

This chapter uses video lessons and practice problems to help your students meet the Common Core State Standards in math. You'll find the resources you need to teach students all about algebraic expressions.

Standard: Apply properties of operations as strategies to add, subtract, factor, and expand linear expressions with rational coefficients. (CCSS.MATH.CONTENT.7.EE.A.1)

Standard:Understand that rewriting an expression in different forms in a problem context can shed light on the problem and how the quantities in it are related. For example, a + 0.05a = 1.05a means that 'increase by 5%' is the same as 'multiply by 1.05.' (CCSS.MATH.CONTENT.7.EE.A.2)

Students who have mastered this standard are able to use the properties of operations to create equivalent expressions. Use the lessons in this chapter to help students learn about the following:

• Simple algebraic expressions and variables
• Associative, commutative and distributive properties
• Difference between distributing or adding first
• Distributing expressions with numbers and variables
• Multiple-term distribution
• Combining like terms
• Factoring and simplifying expressions

You'll know when your students have achieved mastery of this standard when they are able to apply the properties of operations to add, subtract, expand and factor expressions. They'll also be able to understand that rewriting an expression in different forms can help to clarify a math problem.

### How to Use These Lessons in Your Classroom

Below are some tips to help you incorporate these materials into your lesson plan to meet the Common Core standards.

#### Distribution Worksheet

Show students the lesson 'Distributing First vs. Adding First,' then give them a worksheet with sample expressions. Ask students to simply the expressions both ways, if possible. Then have students determine the simplest method for each expression.

#### Create a Quiz on Like Terms

Watch the video 'Combining Like Terms in Algebraic Expressions.' Let students write quiz questions that involve combining like terms. Compile the questions and then assign them to the class. Practicing this way can make students more aware of the like terms that they should be looking to combine.

#### Use Lesson Quizzes as Bell Ringers

Assign the practice quizzes that accompany each chapter as a bell ringer activity. Have students complete the quiz at the beginning of class. Go over the answers together and address problem areas in that day's classroom instruction.
