- I can check my answer and spot a mistake.
Before and after
Needs first: Value of a digit in four-digit numbers
Leads to: Read and write numbers to 1 000 000 in words
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 (Value of a digit in four-digit numbers). Students answer on mini whiteboards.
- Show answers together and note who needs support in the main task.
- In 3259, which place is the digit 2 in? (ones / tens / hundreds / thousands) → hundredsPrompt: Name the places from the right: ones, tens, hundreds, thousands.
- What is the value of the digit 6 in 4506? → 6Prompt: Which place is the digit in?

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 four-digit numbers in words. 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 in digits: three thousand eighty-six
- Step 1: 3086
- Answer: 3086
- 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 in digits: four thousand one hundred twenty-one → 4121Prompt: The word 'thousand' tells you the first digit.
- How do you write 7840 in words? (seven thousand eight hundred fifty / seven thousand eight hundred forty / seven thousand nine hundred forty / seven thousand four hundred eighty) → seven thousand eight hundred fortyPrompt: Read the thousands first, then the hundreds, then the last two digits.
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.
- How do you write 2179 in words? (two thousand one hundred seventy-nine / two thousand one hundred eighty-nine / two thousand seven hundred nineteen / two thousand two hundred seventy-nine) → two thousand one hundred seventy-ninePrompt: Read the thousands first, then the hundreds, then the last two digits.
- Write in digits: eight thousand four hundred ninety-eight → 8498Prompt: The word 'thousand' tells you the first digit.
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

- Give the first step of each question, or a partly worked example to finish.
- Pair with a confident partner for the guided practice.
Stretch
- Move on to: Read and write numbers to 1 000 000 in words.
- Explain a common mistake in writing and how to fix it.
