Key Concepts

  • Counting by 10s
  • Skip counting
  • Number patterns

Learning Objectives

  • Students will be able to count by 10s from 10 to 150.
  • Students will be able to identify the pattern when counting by 10s.
  • Students will be able to associate counting by 10s with real-world scenarios.

Educator Instructions

  • Introduction (5 mins)
    Begin by asking students if they've ever been to the ocean or seen ocean animals. Introduce the video and explain that they'll be going on an underwater adventure to learn about counting by 10s.
  • Video Viewing (5 mins)
    Play the 'Grandma and Grandpa Count by 10s to 150' video. Encourage students to move like the sea animals as they count along.
  • Discussion (5 mins)
    After the video, discuss what they saw and learned. Ask them what animals they saw, and what they noticed about the numbers when they counted by 10s.
  • Activity: Number Line (10 mins)
    Create a number line on the board from 0 to 150. Have students take turns pointing to the numbers as the class counts by 10s together. Highlight the pattern (the ones digit is always 0).
  • Activity: Counting Objects (10 mins)
    Use manipulatives like blocks or counters. Group them into sets of 10. Have students count the groups by 10s (e.g., 1 group is 10, 2 groups are 20, etc.).
  • Wrap Up (5 mins)
    Review counting by 10s. Ask students to give examples of when they might use counting by 10s in real life (e.g., counting dimes, counting fingers and toes on a group of people).

Interactive Exercises

  • Clap and Count
    Have students clap their hands and count by 10s together, starting at 10 and going to 150. Vary the speed to make it more engaging.
  • Act It Out
    Assign different students to be 'tens'. Give them a number (10, 20, 30...). Have them stand in order, demonstrating the sequence of counting by tens.
