Lesson 26: How Do We Write Numerical and Algebraic Expressions?

Introduction

In this lesson, you will learn how to write numerical and algebraic expressions. 

Yesterday, we learned how to evaluate algebraic expressions. Today, we will learn how to write numerical and algebraic expressions using the vocabulary from the other day.

 

How to Write Numerical and Algebraic Expressions

Before we get started, please complete the following: 

        1. In your journal, label the top of your next page the following: How to Write Numerical and Algebraic Expressions.

Look at the slideshow below. Record all of the examples in your journal under the title. 

Writing Numerical and Algebraic Expressions

The key to success with writing numerical and algebraic expressions is by using the vocabulary chart in your journal. This will help you to identify what each expression means. Let’s continue to practice this skill with the activity below.

Flipgrid:

We have learned several new mathematical vocabulary words. In your video, using your own words, answer the following questions: 

  • What is a variable? 
  • What is an algebraic expression?

Go to the next page to complete the Flipgrid assignment.
