Objective and success criteria
Students will: Read and write number words to 100.
- I can answer questions on today's skill on my own, without help.
- I can explain each step and say why it works.
- I can check my answer and spot a mistake.
Before and after
Needs first: Number words zero to ten; Tens and ones
Leads to: Read and write number words to 1000
Materials: Place value chart, Base-ten blocks or a number line, Mini whiteboards and pens, Printed student sheet (below).
Warm-up · 5 min
- Quick retrieval from earlier learning (Number words zero to ten; Tens and ones). Students answer on mini whiteboards.
- Show answers together and note who needs support in the main task.
- Write "three" as a number. → 3Prompt: Say the word out loud.
- Which word is 4? (three / five / four / six) → fourPrompt: Count up to 4 and listen to the last word you say.

Hook · 5 min
- 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.
- Write "sixty-four" in digits. → 64Prompt: The first part of the word tells the tens.
- Which is the word for 23? (thirty-two / twenty / thirty-three / twenty-three) → twenty-threePrompt: 23 has 2 tens. Find the word that starts with that tens word.
You do: independent practice · 10 min
- Students work on the student sheet. Circulate and check the first two answers of every student early.
- Students who finish: write a question of their own for a partner, with the answer.
The 8 questions are on the student sheet below, with answers in the key.
Exit ticket · 5 min
- Two questions on their own. Sort answers into got it / nearly / not yet to plan the next lesson.

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).
Support and stretch
Support
- Review first: Number words zero to ten.
- Use concrete materials: place value chart.
- Give the first step of each question, or a partly worked example to finish.
- Pair with a confident partner for the guided practice.
