Decide what to do with a remainder
Multiplication and division
CCSS 4.OA.A.3England: Y5 Multiplication and division
Objective and success criteria
Students will: Decide what to do with a remainder.
- 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: Division with remainders
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 · 4 min
- Quick retrieval from earlier learning (Division with remainders). Students answer on mini whiteboards.
- Show answers together and note who needs support in the main task.
- What is the remainder when 34 is divided by 3? → 1Prompt: Which multiple of 3 is just below 34?
- 19 children are going on a trip. Each minibus holds 4 children. How many minibuses are needed? → 5Prompt: Divide 19 by 4. Is there a remainder?
- 49 ÷ 5 = ? remainder 4. What is the missing quotient? → 9Prompt: Which multiple of 5 is just below 49?
Hook · 3 min
- Show an array of chairs, eggs or windows and ask how many there are without counting one by one.
- Share the objective: Decide what to do with a remainder. Read the success criteria together.
I do: model it · 7 min
- Work through the example out loud, saying why you do each step, not just what you do.
- Example: 38 people are going on a trip. Each minibus holds 5 people. How many minibuses are needed so everyone can go?
- Step 1: 38 ÷ 5 = 7 r 3
- Step 2: Round up: 8 minibuses.
- Step 3: 8
- Answer: 8
- Pause after each step and ask a student to say what comes next.
We do: guided practice · 6 min
- Do these together. Students try each step on whiteboards before you reveal it.
- Use the hints as prompts rather than giving the answer.
- 16 people are going on a trip. Each minibus holds 5 people. How many minibuses are needed so everyone can go? → 4Prompt: 16 ÷ 5 has a remainder. Can you leave those people behind?
- A baker has 22 cupcakes and puts them into boxes of 5. How many boxes can be completely filled? → 4Prompt: Work out 22 ÷ 5.
You do: independent practice · 7 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 6 questions are on the student sheet below, with answers in the key.
Exit ticket · 3 min
- Two questions on their own. Sort answers into got it / nearly / not yet to plan the next lesson.
- 79 people are going on a trip. Each minibus holds 8 people. How many minibuses are needed so everyone can go? → 10Prompt: 79 ÷ 8 has a remainder. Can you leave those people behind?
- A baker has 30 cupcakes and puts them into boxes of 7. How many boxes can be completely filled? → 4Prompt: Work out 30 ÷ 7.
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: Division with remainders.
- 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.
