Materials: Place value chart, Base-ten blocks or a number line, Mini whiteboards and pens, Printed student sheet (below).
Warm-up · 6 min
- Quick retrieval from earlier learning (Hundreds, tens and ones). Students answer on mini whiteboards.
- Show answers together and note who needs support in the main task.
- What is the value of the digit 6 in 968? → 60Prompt: Which place is the digit in: hundreds, tens or ones?
- Write as a number: 300 + 70 + 1 → 371Prompt: Each part fills one place: hundreds, tens, ones.

- Show a number in the news or a price tag and ask what each digit is worth.
- Share the objective: Value of a digit in four-digit numbers. Read the success criteria together.
I do: model it · 12 min
- Work through the example out loud, saying why you do each step, not just what you do.
- Example: In 8216, which place is the digit 6 in?
- Step 1: There are 0 digits to its right.
- Step 2: The 6 is in the ones place.
- Answer: ones
- Pause after each step and ask a student to say what comes next.
We do: guided practice · 12 min
- Do these together. Students try each step on whiteboards before you reveal it.
- Use the hints as prompts rather than giving the answer.
- In 3784, which place is the digit 3 in? (ones / tens / hundreds / thousands) → thousandsPrompt: Name the places from the right: ones, tens, hundreds, thousands.
- What is the value of the digit 8 in 6804? → 800Prompt: Which place is the digit in?
You do: independent practice · 17 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 · 7 min
- Two questions on their own. Sort answers into got it / nearly / not yet to plan the next lesson.
