Materials and Preparation

  • Students will understand the concept of multiplying by 11.
  • Students will correctly complete multiplication sentences involving multiplying by 11.
  • Students will solve multiplication problems involving the number 11.

Learning Objectives

This lesson focuses on teaching students the skill of multiplying by 11. Students will learn how to multiply any number by 11 using visual aids such as arrays and number lines. They will complete multiplication sentences and solve problems involving multiplying by 11 to reinforce this concept.

Introduction

Begin by asking students to think about what happens when they multiply a number by 11. Explain that multiplying by 11 can be visualized using arrays or number lines. Show a simple example on the board: "If I have 11 groups of 1 dot, how many dots do I have in total?" Write on the board: 11×1=11.

Explicit Instruction/Teacher modeling

Explain that multiplying by 11 is a quick way to increase a number significantly. Use several examples to demonstrate this:

  • 3×11=33
  • 5×11=55
  • 11×2=22

Show the visual representation of these problems using arrays and number lines. For example, show an array of 11 rows with 1 dot in each row to demonstrate 11×1. Then use a number line to count by ones up to 11.

Guided Practice

Provide students with the TeachTastic Worksheet Pack for Multiply by 11. Work through the first few problems together as a class. Use manipulatives to visually demonstrate the problems if necessary. For example, use 11 groups of counters to show that the total number of counters is the original number times 11.

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:

  • 3×11=
  • 0×11=
  • 11×4=

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 11.
  • Introduce the concept of multiplying by other numbers and comparing the results.
  • Offer additional word problems that incorporate multiplying by 11 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 11.

Review and closing

Summarize the key points of the lesson. Ask students to share what they learned about multiplying by 11. Address any remaining questions and clarify misconceptions.

Misconceptions

  • Students may think multiplying by 11 changes the number in an unpredictable way. Address this by using multiple examples and emphasizing the consistent pattern.
  • Students may confuse multiplying by 11 with adding 11. Clarify this by demonstrating with manipulatives and examples.
  • Students may forget the pattern of multiplication by 11. Reinforce this with repeated practice and examples.
