Educator Instructions

  • Introduction (5 mins)
    Begin by asking students what numbers they already know how to read and write. Briefly review numbers 1-9. Show the video 'Read and Write Numbers up to 120 - First Grade Math (1.NBT.1.S1-S3)' from Boddle Learning.
  • Understanding Numbers 10-19 (10 mins)
    Discuss the numbers from 10 to 19. Emphasize the 'teen' ending and how they are formed. Write examples on the board and have students practice reading them aloud.
  • Understanding Numbers 20-120 (15 mins)
    Explain how numbers greater than 20 are formed with 'ty' endings (e.g., twenty, thirty). Break down examples like 76 (seventy and six). Practice writing these numbers in both word and numeral form.
  • Writing Numbers from Words (15 mins)
    Reverse the process. Provide numbers written as words (e.g., twenty-seven) and have students write them as numerals. Emphasize the addition of tens and ones to form the whole number.
  • Wrap-up (5 mins)
    Review the key concepts of the lesson. Ask students to share what they learned and answer any remaining questions.

Interactive Exercises

  • Number Writing Race
    Divide the class into two teams. Call out a number (e.g., 82) and have one member from each team race to write the number correctly on the board in numeral and word form. The first team to write it correctly wins a point.
  • Tens and Ones Breakdown
    Provide students with worksheets containing two-digit numbers. Students must circle the tens digit and underline the ones digit. Then, they write the number as the sum of its tens and ones (e.g., 45 = 40 + 5).

Discussion Questions
