Learning Objectives

  • Students will understand the concept of multiplying by 10.
  • Students will correctly complete multiplication sentences involving multiplying by 10.
  • Students will solve multiplication problems involving the number 10.

Introduction

Begin by asking students to think about what happens when they multiply a number by 10. Explain that multiplying by 10 is like adding a zero to the end of the number. Show a simple example on the board: "If I have 8 groups of 10 dots, how many dots do I have in total?" Write on the board: 8×10=80.

Explicit Instruction/Teacher modeling

Explain that multiplying by 10 is a quick way to increase a number by tenfold. Use several examples to demonstrate this:

  • 10×6=60
  • 10×7=70
  • 10×8=80

Show the visual representation of these problems using arrays and number lines. For example, show an array of 8 rows with 10 dots in each row to demonstrate 8×10. Then use a number line to count by tens up to 80.

Guided Practice

Provide students with the TeachTastic Worksheet Pack for Multiply by 10. Work through the first few problems together as a class. Use manipulatives to visually demonstrate the problems if necessary. For example, use 10 groups of counters to show that the total number of counters is the original number times 10.

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:

  • 10×6=
  • 10×7=
  • 10×8=

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 10.
  • Introduce the concept of multiplying by other numbers and comparing the results.
  • Offer additional word problems that incorporate multiplying by 10 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 10.

Review and closing

Summarize the key points of the lesson. Ask students to share what they learned about multiplying by 10. Address any remaining questions and clarify misconceptions.

Misconceptions

  • Students may think multiplying by 10 changes the number in an unpredictable way. Address this by using multiple examples and emphasizing the consistent pattern of adding a zero.
  • Students may confuse multiplying by 10 with adding 10. Clarify this by demonstrating with manipulatives and examples.
  • Students may forget the pattern of multiplication by 10. Reinforce this with repeated practice and examples.
