Introduction (5 minutes)

• Welcome the students and briefly introduce the topic of teen numbers.
• Ask the students if they know what comes after 10. Discuss briefly, and introduce the term "teen numbers."
• Show flashcards of each teen number (11-19) and ask students to repeat after you.

Direct Instruction (10 minutes)

• Explain the concept of teen numbers:
  • Emphasize that each teen number is made of "ten and some more."
  • Write the numbers 11 to 19 on the whiteboard, highlighting the fact that they all contain "10."

Example:

• 11 = 10 + 1

• 12 = 10 + 2

• Continue this pattern up to 19.

• Show how to write each number and demonstrate using ten frames. Fill ten frames with counters to visualize the addition of numbers.

Guided Practice (10 minutes)

• Pass out counting cubes or blocks. Ask students to represent each teen number with blocks.
• Call out a teen number, and have students build the number using their blocks.
• After building the number, ask them to show their blocks to the class and say the number out loud.

Independent Practice (5 minutes)

• Distribute worksheets that include activities like:
  • Tracing teen numbers.
  • Matching teen numbers with pictures that show the corresponding quantity.
• Allow students to work on these activities individually or in pairs.

Conclusion (2 minutes)

• Review what the students have learned about teen numbers.
• Ask several students to share a teen number they learned today and how to break it down (for example, “12 is 10 and 2.”).
• Encourage enthusiasm about learning new numbers and their importance.

Assessment

• Monitor students during guided practice and independent practice.
• Evaluate the completed worksheets to assess understanding.

Reminders/ Next Steps

• Remind students to practice writing their teen numbers at home.
• In the following class, students will explore the concept of counting beyond 19 and introducing 20.
