  • Show a number in the news or a price tag and ask what each digit is worth.
  • Share the objective: Read and write number words to 100. Read the success criteria together.

I do: model it · 10 min

  • Work through the example out loud, saying why you do each step, not just what you do.
  • Example: Write "eighty-five" in digits.
  • Step 1: "eighty-five" = 85
  • Answer: 85
  • Pause after each step and ask a student to say what comes next.

We do: guided practice · 10 min

  • Do these together. Students try each step on whiteboards before you reveal it.
  • Use the hints as prompts rather than giving the answer.
  1. Write "twenty-six" in digits. → 26Prompt: The first part of the word tells the tens.
  2. Which is the word for 32? (forty-two / thirty-two / thirty / twenty-three) → thirty-twoPrompt: 32 has 3 tens. Find the word that starts with that tens word.

You do: independent practice · 10 min

Watch out for

  • Reading 1,045 as one thousand four hundred five: point to each place and say its value.
  • Thinking a longer number is always bigger, even with decimals (0.45 vs 0.5).
