# Writing Numerical Expressions with Exponents Lesson Plan

## Overview

Ever wondered how to teach writing numerical expressions in an engaging way to your 5th or 6th-grade students? Thinking of how to explain steps to translate between verbal phrase and expressions?

In this lesson plan, students will learn about writing numerical expressions and their real-life applications. Through artistic, interactive guided notes, check for understanding, practice coloring worksheet, and a maze worksheet, students will gain a comprehensive understanding of writing numerical expressions.

The lesson ends with a real-life example that explores how writing numerical expressions are used in practical everyday math situations.

## Learning Objectives

After this lesson, students will be able to:

• Identify keywords for different mathematical operations (addition, subtraction, multiplication, division) in word problems

• Write numerical expressions using whole number exponents

• Demonstrate understanding of numerical expressions by completing practice problems

• Write numerical expressions to model real-life math problems

## Prerequisites

Before this lesson, students should be familiar with:

• Knowledge of whole numbers and their properties

• Basic understanding of exponents and their meaning

## Key Vocabulary

• Numerical expressions

• Operations

• Exponents

## Procedure

### Introduction

As a hook, ask students why writing numerical expressions is important in real-life situations.

Use the first page of the guided notes to introduce the concept of writing numerical expressions using keywords for addition and subtraction. Walk through the key points of identifying keywords that signals specific operations (i.e. sum, difference, product, quotient, etc) and translating them into numerical expressions. Students will be filling in keywords on the guided notes while you teach.

Use the second page of the guided notes to practice translating between verbal phrase and expressions. There are multiple sections on the page to allow for students to apply the keywords they've just learned about on page 1.

Use the third page of the guided notes to introduce writing numerical expressions with whole-number exponents. Walk through the key points of understanding exponents, keywords (i.e. squared, cubes) and incorporating them into numerical expressions.

Based on student responses during the introduction, reteach concepts that students need extra help with. If your class has a wide range of proficiency levels, you can pull out students for reteaching, and have more advanced students begin working on the practice exercises.

### Practice

Have students practice writing numerical expressions using the practice worksheet provided in the resource(pg. 2-3) as well as the maze activity (pg. 4). Walk around to answer student questions.

Fast finishers can dive into the color by number activity (pg. 5) for extra practice. You can alternatively assign it as homework for the remainder of the class.

### Real-Life Application

Using the last page of the guided notes (pg. 6), bring the class back together, and introduce the concept of writing and using numerical expressions in real-life scenarios, such as calculating expenses for a school trip or modeling the cost of running a small business.

Students read about scenarios where writing numerical expressions can be helpful in real life as well as complete a short self assessment on the mastery of this math topic.
