Key Concepts

  • Division as repeated subtraction
  • Dividend, divisor, and quotient
  • Understanding division in real-world contexts

Learning Objectives

  • Students will be able to define dividend, divisor, and quotient.
  • Students will be able to explain division as repeated subtraction.
  • Students will be able to solve division problems using repeated subtraction.

Educator Instructions

  • Introduction (5 mins)
    Begin by asking students what they already know about division. Discuss different ways to think about division. Introduce the video as a fun way to learn about division as repeated subtraction.
  • Video Viewing (5 mins)
    Play the NUMBEROCK video "Division Song For Kids | Division as Repeated Subtraction | 3rd Grade - 4th Grade." Encourage students to sing along and pay attention to the examples.
  • Concept Review (10 mins)
    After the video, review the key terms: dividend, divisor, and quotient. Use the basketball and soccer ball examples from the video to illustrate these terms. Explain how repeated subtraction works as a method of division.
  • Practice Problems (15 mins)
    Provide students with practice problems involving division that can be solved using repeated subtraction. Start with simple problems and gradually increase the difficulty. Examples: 15 ÷ 3, 20 ÷ 5, 24 ÷ 4.
  • Real-World Application (10 mins)
    Present real-world scenarios where division as repeated subtraction can be used. For example: 'You have 18 cookies and want to share them equally among 3 friends. How many cookies does each friend get?' Guide students to solve these problems using repeated subtraction.
  • Assessment (10 mins)
    Have students complete the multiple choice and fill in the blank quizzes to assess their understanding of the lesson. Review the answers as a class.

Interactive Exercises

  • Group Division Activity
    Divide the class into small groups. Give each group a set of manipulatives (e.g., counters, blocks). Present a division problem and have each group use the manipulatives to demonstrate repeated subtraction to solve the problem.
