Key Concepts

  • Counting by tens
  • Understanding groups of ten
  • Number patterns

Learning Objectives

  • Students will be able to count forward by tens to 100.
  • Students will be able to count backward by tens from 100.
  • Students will understand that each number in the sequence (10, 20, 30...) represents a group of ten.

Educator Instructions

  • Introduction (5 mins)
    Begin by asking students what they already know about counting. Introduce the idea of counting by tens instead of ones. Explain that this is a faster way to count larger numbers.
  • Video Viewing (5 mins)
    Show the video 'Grade 1: Math Lesson #43 Counting by 10's to 100'. Encourage students to count along with the teacher in the video.
  • Guided Practice (10 mins)
    Use a hundreds chart to visually demonstrate counting by tens. Point to each number as you count aloud with the class: 10, 20, 30, and so on. Then, practice counting backward from 100 to 10.
  • Independent Practice (10 mins)
    Give each student a worksheet with numbers from 1 to 100. Have them color in the numbers they say when counting by tens. This will help them visualize the pattern.
  • Wrap-up (5 mins)
    Review counting by tens and ask students when they might use this skill in real life (e.g., counting money). Briefly introduce the concept of place value (tens and ones).

Interactive Exercises

  • Clap and Count
    Students clap their hands every time they say a number while counting by tens. This adds a physical element to the lesson.
  • Number Line Jump
    Draw a number line on the board. Have students take turns jumping along the number line by increments of ten, saying the number they land on each time.
