Materials and Preparation

  • Whiteboard and markers
  • TeachTastic Worksheet Pack for Multiply by 2
  • Manipulatives for hands-on practice (e.g., counters, blocks)
  • Chart paper and markers for group activities

Learning Objectives

  • Students will understand the concept of multiplying by 2.
  • Students will correctly complete multiplication sentences involving multiplying by 2.
  • Students will use arrays and number lines to visualize multiplication by 2.

Introduction

Begin by asking students to think about what happens when they double a number. Explain that multiplying by 2 is like adding the number to itself. Show a simple example on the board: "If I have 2 groups of 6 dots, how many dots do I have in total?" Write on the board: 2×6=12.

Explicit Instruction/Teacher modeling

Explain the steps to multiply by 2 using arrays and number lines:

  1. Using Arrays:

    • Draw an array with 2 rows of 6 dots. Explain that each row represents one group of 6.
    • Count all the dots to find the total. For 2×6, there are 12 dots in total.
    • Write the multiplication sentence: 2×6=12.

  2. Using Number Lines:

    • Draw a number line from 0 to 20. Mark increments of 6.
    • Show how to count forward by 6s, twice. For 2×6, start at 0, move to 6, then move to 12.
    • Write the multiplication sentence: 2×6=12.

Guided Practice

Provide students with the TeachTastic Worksheet Pack for Multiply by 2. Work through the first few problems together as a class, using manipulatives like counters to create arrays and number lines to visualize the problems.

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:

  • 2×3=
  • 2×4=
  • 2×5=

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 2.
  • Introduce the concept of multiplying by other numbers and comparing the results.
  • Offer additional word problems that incorporate multiplying by 2 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 2.

Review and closing

Summarize the key points of the lesson. Ask students to share what they learned about multiplying by 2. Address any remaining questions and clarify misconceptions.

Misconceptions

  • Students may think multiplying by 2 changes the number in an unpredictable way. Address this by using multiple examples and emphasizing the consistent pattern of doubling.
  • Students may confuse multiplying by 2 with adding 2. Clarify this by demonstrating with manipulatives and examples.
  • Students may struggle with using arrays or number lines. Reinforce this with repeated practice and examples.
