Key Concepts

  • Counting from 0 to 100
  • Identifying patterns in numbers
  • Understanding tens and ones
  • Number sequencing

Learning Objectives

  • Students will be able to count from 0 to 100.
  • Students will be able to identify patterns in a number grid.
  • Students will be able to recognize the tens and ones place in two-digit numbers.

Educator Instructions

  • Introduction (5 mins)
    Begin by asking students if they can count to 100. Briefly discuss why counting is important. Introduce the Khan Academy video and explain that it will show us a fun way to count and see patterns.
  • Video Viewing (7 mins)
    Play the Khan Academy video 'Number grid | Counting | Early Math | Khan Academy'. Encourage students to follow along and notice the patterns the video explains.
  • Grid Exploration (10 mins)
    Distribute pre-made number grids (0-100) to each student. As a class, point out and color the numbers in the same way the video does. Have students practice tracing the numbers and follow the patterns.
  • Pattern Practice (8 mins)
    Ask students to identify different patterns they see in the number grid. For example, what happens to the ones place as you go down a column? What happens to the tens place as you go across a row?
  • Wrap-up (5 mins)
    Review the key concepts of counting to 100, identifying patterns, and understanding tens and ones. Briefly discuss how the number grid can help with addition and subtraction later on.

Interactive Exercises

  • Number Grid Fill-In
    Provide students with a partially filled number grid and ask them to fill in the missing numbers.
  • Pattern Coloring
    Give students a blank number grid and ask them to color in numbers based on a specific pattern (e.g., color all the numbers ending in 5 blue).

Discussion Questions

  • What patterns did you see in the number grid?
  • How does the number grid help us count higher?
  • Can you think of any other patterns in numbers?
