Divide a four-digit number by a one-digit number
Multiplication and division
CCSS 4.NBT.B.6England: Y5 Multiplication and division
Objective and success criteria
Students will: Divide a four-digit number by a one-digit number.
- 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: Divide a three-digit number by a one-digit number
Leads to: the next skill in this area.
Materials: Counters for arrays, Multiplication grid, Base-ten blocks, Mini whiteboards and pens, Printed student sheet (below).
Warm-up · 5 min
- Quick retrieval from earlier learning (Divide a three-digit number by a one-digit number). Students answer on mini whiteboards.
- Show answers together and note who needs support in the main task.
- 608 ÷ 8 = ? → 76Prompt: Divide the hundreds first, then the tens, then the ones.
- Grace cycles 427 km in 7 weeks, the same distance each week. How many kilometres is that per week? → 61Prompt: Share 427 into 7 equal parts.
- 3 × ▢ = 330. What number is ▢? → 110Prompt: Use the inverse operation.
Hook · 5 min
- Show an array of chairs, eggs or windows and ask how many there are without counting one by one.
- Share the objective: Divide a four-digit number by a one-digit number. 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: 2298 ÷ 6 = ?
- Step 1: 22 ÷ 6 = 3 r 4
- Step 2: 49 ÷ 6 = 8 r 1
- Step 3: 18 ÷ 6 = 3
- Step 4: 2298 ÷ 6 = 383
- Answer: 383
- 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.
- 4350 ÷ 6 = ? → 725Prompt: Use short division, place by place.
- Work out 7909 ÷ 5. Give the remainder. → 4Prompt: Divide place by place.
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.
- Work out 9210 ÷ 7. Give the remainder. → 5Prompt: Divide place by place.
- 3627 ÷ 9 = ? → 403Prompt: Use short division, place by place.
Watch out for
- Thinking multiplying always makes a number bigger.
- Dropping a zero in long multiplication when moving to the tens row.
Support and stretch
Support
- Review first: Divide a three-digit number by a one-digit number.
- Use concrete materials: counters for arrays.
- Give the first step of each question, or a partly worked example to finish.
- Pair with a confident partner for the guided practice.
Stretch
- Explain a common mistake in writing and how to fix it.
- Write a word problem that uses today's skill, then solve a partner's.
