Lesson Plan: Teen Numbers

Subject

Mathematics

Grade Level

Year 1

Duration

30 minutes

Objective

Students will be able to identify, write, and understand teen numbers (11-19).

Materials Needed

Introduction (5 minutes)

  1. Engage the students by asking them if they know any numbers that come after 10.
  2. Introduce the term "teen numbers" and explain that they are the numbers from 11 to 19.
  3. Write the numbers 11 to 19 on the whiteboard and pronounce them out loud.

Direct Instruction (10 minutes)

  1. Explain how to form teen numbers:

    • Teen numbers start with "1" and are followed by another digit from 0-9.
    • Show flashcards for each teen number (11, 12, 13, 14, 15, 16, 17, 18, 19) and ask students to repeat after you.

  2. Demonstrate counting teen numbers:

    • Count together from 11 to 19, emphasizing the first digit "1" in each teen number.

  3. Teach how to recognize teen numbers in a sequence:

    • Ask students to point at each flashcard as you say the number out loud together.

Guided Practice (10 minutes)

  1. Hands-on Activity:

    • Distribute counting blocks. Have students create groups of blocks that represent each teen number.
    • For example, they can make 11 blocks or 14 blocks.

  2. Worksheet Activity:

    • Hand out worksheets where students will:
      • Circle the teen numbers.
      • Fill in the missing teen numbers in a sequence (e.g., 11, , 13, , 15).
      • Match flashcards with the corresponding number written out.

Closure (5 minutes)

  1. Review the teen numbers together as a class.
  2. Ask a few students to share one teen number they created with blocks.
  3. Highlight the importance of teen numbers in everyday life.
