Multiply by 0 or 1

Prerequisite Skill

Multiply by 0

Materials and Preparation

  • Whiteboard and markers
  • TeachTastic Worksheet Pack for Multiply by 0 or 1
  • Manipulatives for hands-on practice (e.g., counters, blocks)
  • Chart paper and markers for group activities

Learning Objectives

  • Students will understand that any number multiplied by 1 remains the same (identity property of multiplication).
  • Students will understand that any number multiplied by 0 is 0 (zero property of multiplication).
  • Students will correctly complete multiplication sentences involving multiplying by 0 or 1.

Introduction

Begin by asking students to think about the number 1. Explain that 1 is a unique number in multiplication because it does not change the value of the number it is multiplied by. Demonstrate with a simple problem: "If I have 1 group of 4 apples, how many apples do I have?" Write on the board: 1×4=4.

Next, introduce the concept of multiplying by 0. Ask, "If I have 0 groups of 5 apples, how many apples do I have?" Write on the board: 0×5=0.

Explicit Instruction/Teacher modeling

Explain that the identity property of multiplication states that any number multiplied by 1 remains the same. Use multiple examples: 1×3=3, 1×7=7.

Next, explain the zero property of multiplication, stating that any number multiplied by 0 is 0. Use multiple examples: 5×0=0, 9×0=0.

  • Offer additional word problems that incorporate multiplying by 0 or 1 in real-life scenarios.

Assessment

Use the specific assessment worksheets from the TeachTastic Worksheet Pack to evaluate students' understanding. Ensure the assessment includes both multiplication by 0 and 1.

Review and closing

Summarize the key points of the lesson. Ask students to share what they learned about multiplying by 0 and 1. Address any remaining questions and clarify misconceptions.

Misconceptions

  • Students may think multiplying by 1 changes the number. Address this by using multiple examples and emphasizing the identity property.
  • Students may confuse multiplying by 0 with adding 0. Clarify this by demonstrating with manipulatives and examples.
  • Students may forget the zero property of multiplication. Reinforce this with repeated practice and examples.
