Number Names to 100

Writing Numbers in Words: Up to 100

Description: Practice writing number words for two-digit numbers up to 100.
Student Tips:

• Write the tens part first (twenty, thirty, forty, … ninety).

• Add the ones part if needed (e.g., 42 = forty-two).

• Use a hyphen between tens and ones (twenty-five, sixty-seven).
  Teaching Instruction: Teach students to break apart numbers into tens and ones before writing. Use number charts to show how words combine (e.g., “seventy + six” = seventy-six).
