Key Concepts

  • Multiples of 9
  • Skip Counting
  • Patterns in Multiplication

Learning Objectives

  • Students will be able to skip count by 9s up to 108.
  • Students will be able to identify multiples of 9.
  • Students will be able to recognize the pattern in the multiples of 9.

Educator Instructions

  • Introduction (5 mins)
    Begin by asking students what they already know about the number 9. Discuss where they might see the number 9 used in everyday life (e.g., sports teams, number of planets). Introduce the concept of skip counting as a way to find multiples of a number.
  • Video Time! (5 mins)
    Play the NUMBEROCK video 'Skip Counting by 9 Song'. Encourage students to sing along and dance to the song. Point out the 1920s theme and how music can help remember mathematical concepts.
  • Discussing the Multiples (10 mins)
    After the video, write the multiples of 9 (9, 18, 27, 36, 45, 54, 63, 72, 81, 90, 99, 108) on the board. Ask students if they notice any patterns. (e.g., the tens digit increases by one, and the ones digit decreases by one; the digits always add up to 9 until you get to 99 and 108). Discuss how these patterns can help them remember the multiples of 9.
  • Interactive Activity: Number Line Hop (10 mins)
    Create a number line from 0 to 110 on the floor using tape. Have students take turns hopping along the number line, only landing on multiples of 9. Each student should say the multiple of 9 they land on. This reinforces skip counting in a kinesthetic way.
  • Worksheet Practice (10 mins)
    Distribute a worksheet with skip counting exercises. For example, students could fill in missing numbers in a sequence (9, __, 27, __, 45) or solve simple word problems involving multiples of 9 (e.g., 'There are 9 cupcakes in a box. How many cupcakes are in 5 boxes?').

Interactive Exercises

  • 9s Hand Trick
    Demonstrate the 9s hand trick. Hold up both hands. To multiply 9 by a number, count that many fingers from the left and bend that finger down. The fingers to the left of the bent finger represent the tens digit, and the fingers to the right represent the ones digit.

Discussion Questions

  • What patterns did you notice in the multiples of 9?
  • How can skip counting help you with multiplication?
  • Can you think of real-life situations where you might use skip counting by 9s?
