Materials and Preparation

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

Learning Objectives

  • Students will understand the identity property of multiplication.
  • Students will correctly complete multiplication sentences involving multiplying by 1.
  • Students will solve multiplication problems involving the number 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. Show a simple example on the board: "If I have 1 group of 10 apples, how many apples do I have?" Write on the board: 1×10=10.

Explicit Instruction/Teacher modeling

Explain that the identity property of multiplication states that any number multiplied by 1 remains the same. Use several examples to demonstrate this:

  • 1×3=3
  • 1×7=7
  • 1×10=10

Discuss why this property is useful and important in multiplication.

Guided Practice

Provide students with the TeachTastic Worksheet Pack for Multiply by 1. Work through the first few problems together as a class. Use manipulatives to visually demonstrate the problems if necessary. For example, use 1 group of counters to show that the number of counters does not change when multiplied by 1.

Independent Practice

Assign specific worksheets from the TeachTastic Worksheet Pack for students to complete independently. Circulate the room to provide assistance and check for understanding. Examples of problems might include:

  • 3×1=
  • 6×1=
  • 10×1=

Differentiation

Support

  • Offer additional practice with manipulatives for students who need it.
  • Provide step-by-step written guides for solving multiplication problems.
  • Pair students who are struggling with a peer tutor for additional support.

Extension

  • Provide challenging problems involving larger numbers multiplied by 1.
  • Introduce the concept of multiplying by other numbers and comparing the results.
  • Offer additional word problems that incorporate multiplying by 1 in real-life scenarios.

Assessment

Use the specific assessment worksheets from the TeachTastic Worksheet Pack to evaluate students' understanding. Ensure the assessment includes a variety of problems multiplying by 1.

Review and closing

Summarize the key points of the lesson. Ask students to share what they learned about multiplying by 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 1 with adding 1. Clarify this by demonstrating with manipulatives and examples.
  • Students may forget the identity property of multiplication. Reinforce this with repeated practice and examples.
