Division: Splitting Things Into Equal Groups

with Lumi

Lumi stands at a sunny picnic table in a park, carefully placing strawberries one by one onto four small plates, making sure every plate gets the same amount, with a big basket of strawberries beside them.

Explain what division means using the words 'equal groups' and 'sharing fairly'.
Identify the total, the number of groups, and the amount in each group in a division problem.
Calculate a division result by sharing objects equally across groups.
Represent a division situation with a number equation using the ÷ symbol.
Check a division answer by counting how many are in one group after sharing equally.

Key terms

Division: Splitting a total into equal groups.
Total: All the things you start with.
Equal groups: Groups that each have the same amount.
Fair share: When everyone gets the same number.

Sharing Things Fairly

Division is all about being fair. When you split snacks so everyone gets the same number, you are dividing! You start with a total, like 12 cookies. Then you pick how many groups, like 3 friends. Division tells you how many each friend gets. Nobody gets more and nobody gets less. That is what fair sharing means in math.

Deal It Out Like Cards

If you are not sure of the answer, deal the things out one at a time. Give one to each group, then go around again and give one more to each. Keep going until none are left. Then count how many ended up in just one group. That number is your answer! This trick always works and helps you see why division gives equal groups.

Worked examples

Share 15 stickers among 3 kids equally.

The total is 15 and there are 3 groups.
Deal one sticker to each kid, again and again, until none are left.
Count one kid's pile: 15 divided by 3 equals 5.

Answer: 5 stickers each

Hey there! I'm Lumi, and today we're going to learn about division — one of the most useful skills in everyday life. Imagine you have 12 strawberries and 4 friends. You want everyone to get the same number. That's division! Division means splitting a total into equal groups so no one gets more or less than anyone else. Here's the big idea: division answers the question 'How many in EACH group?' You know the total and how many groups there are, and division tells you how much each group gets. For 12 strawberries shared among 4 friends, we write: 12 ÷ 4 = 3. That means each friend gets 3 strawberries. Here's a hint when you get stuck: deal them out one at a time, like dealing cards. Give one to each group, then one more to each, and keep going until none are left. Count how many ended up in one group — that's your answer!

Activity

Drag the strawberries onto the plates so every plate gets the same number of strawberries.

Practice

Share 10 apples equally among 2 baskets. How many each?

Write the division sentence for 18 grapes in 3 bowls.

Common mistakes to avoid

The number of groups is the answer.No. The answer is how many are in one group, not how many groups.
Division means take some away.No. Division splits into equal groups; taking away is subtraction instead.

Check your understanding

A teacher has 20 pencils and wants to give the same number to each of 5 students. Which equation shows how many pencils each student gets?

There are 24 grapes shared equally into 6 bowls. How many grapes are in each bowl?

You share 12 strawberries equally among 4 friends. Which number sentence shows how many each friend gets?

Recap

Division means splitting a total into equal groups so everyone shares fairly. You know the total and the number of groups, and division tells you how many go in each group.

Reflect

When have you shared snacks fairly with your friends or family?
