Ocean maths quest: division
A story-led junior maths adventure using reefs, ships and underwater maps to share rewards fairly and split teams into equal groups.
Quick answer
Division is about sharing things equally between groups. When you divide, you split a bigger number into smaller, equal parts.
Learning outcome
By the end of this page, you will be able to share a number of items equally between groups and solve simple division problems using objects, drawings, and real-life situations.
- You can share 12 fish equally between 3 friends
- You can show division with pictures or counters
- You can solve simple division problems like 10 ÷ 2 = 5
- You can explain what happens when you divide by 1 or 0
Why this matters
Division helps you share things fairly with friends, split up rewards, and understand how many items each person gets. Whether you're sharing cookies with siblings, dividing up a treasure map, or splitting a team for a game, division helps you figure out the right amount for everyone.
In games like Ocean Maths Quest, you might need to divide treasure equally between your crew, or split your underwater team into groups to explore different reefs. Understanding division helps you be a better explorer and team leader!
How it works
Division is like sharing. If you have 12 fish and want to share them equally between 3 friends, you need to figure out how many fish each friend gets.
- Start with the total number of items you have
- Decide how many groups you want to share between
- Share the items equally one by one
- Count how many items each group gets
When you divide, you're splitting something into equal parts. You can also think of it as repeated subtraction – how many times can you take away the same number from a bigger number?
Examples you can see
Let's go on an Ocean Maths Quest! You and your friends have found a treasure chest with 15 seashells. You want to share them equally between 5 friends.
Step 1: You have 15 seashells
Step 2: You want to share between 5 friends
Step 3: Give 1 seashell to each friend, one at a time
Step 4: When all seashells are shared, each friend has 3 seashells
This is 15 ÷ 5 = 3
Here are some more examples using different numbers:
| Total Items | Number of Groups | Items per Group | Division Sentence |
|---|---|---|---|
| 8 | 2 | 4 | 8 ÷ 2 = 4 |
| 12 | 3 | 4 | 12 ÷ 3 = 4 |
| 18 | 6 | 3 | 18 ÷ 6 = 3 |
| 20 | 4 | 5 | 20 ÷ 4 = 5 |
Try this with counters or drawing pictures. If you have 10 jellyfish and want to put them into 2 buckets, how many go in each bucket?
Try it as a mini adventure
Imagine you're captain of a pirate ship! You've discovered a sunken treasure with 24 gold coins. You want to share them equally between your crew of 4 sailors.
Adventure Task: Share the 24 coins equally between 4 sailors.
4th time: You have shared 16 coins, 4 coins for each sailor
5th time: You have shared 20 coins, 5 coins for each sailor
6th time: You have shared 24 coins, 6 coins for each sailor
Answer: Each sailor gets 6 coins. This is 24 ÷ 4 = 6
Challenge: What if you had 30 coins and 5 sailors? How many coins would each sailor get?
Common mistakes
- Mistake: Thinking 10 ÷ 2 = 5 and then saying 5 × 2 = 10 is wrong because it's the same answer!
- Why it happens: Children might think that division and multiplication are the same thing.
- Fix: Remember that division splits things apart, and multiplication puts things together.
- Mistake: Forgetting that 5 ÷ 5 = 1, not 0
- Why it happens: It's easy to think that when you divide something by itself, you get nothing.
- Fix: Any number divided by itself equals 1 – think of sharing 5 cookies with 5 friends, each gets 1 cookie!
- Mistake: Trying to divide by 0
- Why it happens: Children may think you can't share with no one.
- Fix: You cannot divide by zero – it's not possible in maths!
Parent and carer guide
Help your child understand division by using everyday examples like sharing snacks or dividing toys. You can use:
- Counters or small objects like buttons or pasta pieces
- Drawings or pictures of groups
- Real-life sharing situations
- Repeating the same division problems with different numbers
What to say: "Let's share these 12 crackers between 3 people. How many does each person get?"
What not to worry about: Don't expect perfect answers right away. Division takes time to understand. Practice with simple sharing tasks.
How to help: Use visual aids, ask questions, and let them explain their thinking. If they get confused, go back to using counters or drawing pictures.
When to celebrate: When they can explain that 12 ÷ 3 = 4 by sharing 12 items into 3 equal groups.

FAQ
What does division mean?
Division means sharing or splitting something into equal parts. For example, if you have 12 cookies and want to share them equally between 3 friends, each friend gets 4 cookies.
How is division different from multiplication?
Multiplication is when you put groups together to make a bigger number. Division is when you split a bigger number into smaller, equal groups. For example, 3 × 4 = 12, and 12 ÷ 4 = 3.
Can you divide by zero?
No, you cannot divide by zero. It's not possible in maths. Think of it like trying to share cookies with no one – it doesn't make sense!
Why do we learn division?
Division helps us share things fairly, solve problems, and understand how many items each person gets. It's useful for sharing food, splitting up teams, and understanding money and time.
What's a good way to practice division?
Practice with real objects like counters, buttons, or toys. Draw pictures of sharing, and use everyday situations like sharing snacks or dividing up toys. The more you practice, the easier it gets!
