Key Concepts

  • Skip Counting
  • Place Value (Hundreds)
  • Number Patterns

Learning Objectives

  • Students will be able to count forward by 100s from 100 to 1,000.
  • Students will be able to count backward by 100s from 1,000 to 100.
  • Students will be able to identify the pattern in counting by 100s.

Educator Instructions

  • Introduction (5 mins)
    Begin by reviewing counting by ones and tens. Ask students to count to 20 by ones, then to 100 by tens. Explain that today, they will learn to count by hundreds.
  • Video Viewing (5 mins)
    Play the YouTube video "Grade 1: Math Lesson # 95: Counting by 100's". Encourage students to count along with the teacher in the video.
  • Guided Practice (10 mins)
    Use a number chart or whiteboard. Point to numbers as you count by 100s together as a class. Practice both forward and backward counting. Emphasize the pattern: each number has 'hundred' in it (e.g., one hundred, two hundred).
  • Activity: Counting Blocks (10 mins)
    If available, use base-ten blocks (hundreds flats). Have students physically count the blocks as you skip count by 100s. This kinesthetic activity reinforces the concept of 'hundreds' as a quantity.
  • Song Time (5 mins)
    Revisit the song from the video or create a new one to reinforce counting by 100s in a fun way. Sing it together as a class multiple times.
  • Wrap-up (5 mins)
    Review what was learned. Ask students to share their favorite part of the lesson. Remind them that they can now count by 100s!

Interactive Exercises

  • Hundred Chart Fill-In
    Provide students with a partially filled-in hundred chart (numbers from 100 to 1000, but with some numbers missing in the 100s sequence). Have them fill in the missing numbers to practice skip counting by 100s.
  • Counting Circles
    Create large circles on the floor, each labeled with a multiple of 100 (100, 200, 300, etc.). Have students hop from circle to circle as they count by 100s. Vary the starting point to reinforce understanding.

Discussion Questions

  • What pattern do you see when we count by 100s?
  • Can you think of a time when you might need to count by 100s in real life?
