Share things out equally
Multiplication and division
CCSS 2.OA.C.3England: Y1 Multiplication and divisionEngland: Y2 Multiplication and division
Objective and success criteria
Students will: Share things out equally.
- 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: Count objects in equal groups
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 · 6 min
- Quick retrieval from earlier learning (Count objects in equal groups). Students answer on mini whiteboards.
- Show answers together and note who needs support in the main task.
- How many groups are there, and how many in each? Then find the total. ( ● ● ● ● ) ( ● ● ● ● ) How many altogether? → 8Prompt: There are 2 groups.
- How many groups are there, and how many in each? Then find the total. ( ● ● ● ) ( ● ● ● ) How many altogether? → 6Prompt: There are 2 groups.
- How many groups are there, and how many in each? Then find the total. ( ▲ ▲ ▲ ▲ ) ( ▲ ▲ ▲ ▲ ) How many altogether? → 8Prompt: There are 2 groups.
Hook · 6 min
- Show an array of chairs, eggs or windows and ask how many there are without counting one by one.
- Share the objective: Share things out equally. 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: Mei and Isla want to share 6 cookies so they both get the same and none are left. Can they do it?
- Step 1: 6 is even: 3 each. Yes.
- Answer: Yes
- 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.
- Nia and Priya want to share 6 cookies so they both get the same and none are left. Can they do it? (Yes / No) → YesPrompt: Share them one at a time between two people.
- Hana and Fatima want to share 8 cookies so they both get the same and none are left. Can they do it? (Yes / No) → YesPrompt: Share them one at a time between two people.
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.
- Fatima and Diego want to share 5 cookies so they both get the same and none are left. Can they do it? (Yes / No) → NoPrompt: Share them one at a time between two people.
- Aisha and Priya want to share 3 cookies so they both get the same and none are left. Can they do it? (Yes / No) → NoPrompt: Share them one at a time between two people.
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: Count objects in equal groups.
- 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.
