Associative Property Fun

Understand the associative property

In this lesson, students will learn about the associative property of addition and multiplication. This property helps simplify calculations and is a fundamental concept in math. Understanding the associative property will aid students in solving math problems more efficiently.

Audience

3rd Grade Math Students

Time

Approach

Materials

Whiteboard and markers, Printed worksheets, and Pencils

Step 1

Introduction

5 minutes

Begin by asking students if they know what the word 'associate' means. Explain that in math, the associative property helps us group numbers in different ways to make calculations easier. Write an example on the board: (2 + 3) + 4 = 2 + (3 + 4).

Step 2

Explanation

5 minutes

Explain the associative property of addition and multiplication. Use simple examples to show that the way numbers are grouped does not change their sum or product. For example, (1 + 2) + 3 = 1 + (2 + 3) and (2 x 3) x 4 = 2 x (3 x 4).

Step 3

Guided Practice

10 minutes

Work through a few problems together as a class. Write problems on the board and ask students to help you solve them using the associative property. For example, (5 + 6) + 7 and 3 x (4 x 5).

Step 4

Independent Practice

7 minutes

Hand out the worksheets and ask students to complete them independently. Walk around the room to provide assistance as needed.

Step 5

Wrap-Up Discussion

3 minutes

Review the answers to the worksheet as a class. Ask students to share what they learned about the associative property and how it can help them in math.
