Ocean maths quest: addition

A story-led junior maths adventure using reefs, ships and underwater maps to combine treasures, supplies and scores without losing track.

Quick answer

Adding numbers together means putting groups of things together to find how many there are in total. You can use your fingers, objects, or drawings to help you add.

Learning outcome

By the end of this page, you will be able to add small numbers together to find totals, using objects, drawings, or number lines. Success signs:
  • You can count on from one number to add another number
  • You can use objects like blocks or toys to show addition
  • You can solve simple addition problems with numbers up to 10
  • You can explain how you added two groups together

Why this matters

Addition is one of the most useful maths skills you'll learn. When you're at the beach, you might count your seashells and then find out how many you have after your friend gives you more. When you're shopping, you might add the prices of two items to see how much they cost altogether. Addition helps you solve problems in games, sports, and everyday life. It's like having a superpower that helps you keep track of how many things you have.

How it works

Addition is when you put groups of things together to find the total. It's like having two piles of toys and counting them all together. Here's how it works:
  1. Start with one group of objects or numbers
  2. Put another group next to it
  3. Count them all together to find the total
You can add numbers in different ways:
  • Counting on your fingers
  • Using physical objects like blocks or beads
  • Using a number line
  • Writing the numbers and adding them up

Examples you can see

Let's imagine you're on an ocean adventure. You find 3 fish and then find 2 more fish. How many fish do you have in total? Method 1: Counting objects
  • Get 3 fish-shaped counters
  • Get 2 more fish-shaped counters
  • Put them all together and count: 1, 2, 3, 4, 5
  • You have 5 fish in total
Method 2: Drawing Draw 3 fish, then draw 2 more fish. Count all the fish you drew: 1, 2, 3, 4, 5. Method 3: Number line Start at 3 on the number line. Jump 2 spaces forward. You land on 5. Method 4: Writing numbers Write 3 + 2 = 5 Here's a table showing different ways to add 3 and 2:
Method What happens Answer
Counting Count 3 then count 2 more 5
Objects Put 3 blocks with 2 blocks 5 blocks
Number line Start at 3, jump 2 spaces 5
Writing Write 3 + 2 = 5 5

Try it as a mini adventure

The Ocean Maths Quest: Treasure Hunt You're on a treasure hunt in the ocean. Your map shows you've found 4 pearls in the first cave. Then you find 3 more pearls in the second cave. How many pearls do you have altogether? Step 1: Count the pearls in the first cave: 1, 2, 3, 4 Step 2: Count the pearls in the second cave: 1, 2, 3 Step 3: Put all the pearls together and count them all: 1, 2, 3, 4, 5, 6, 7 Step 4: You found 7 pearls in total! Mini challenge: You also find 2 seashells in the third cave. How many treasures do you have now? Answer: 7 + 2 = 9 treasures Real-world connection: Think about when you collect things like stickers, coins, or toys. Each time you get more, you add them to your collection. This is like the treasure hunt!

Common mistakes

  • Mistake: Counting the first group twice instead of adding it to the second group
    Why it happens: When you're excited about finding treasures, you might accidentally count the same items twice.
    Fix: Count the first group once, then count the second group once, and count them all together carefully.
  • Mistake: Forgetting to include one of the groups when adding
    Why it happens: Sometimes we get distracted and forget to count one of the items.
    Fix: Use objects to help you keep track. Put one group in front of you and one behind you, then count them all together.
  • Mistake: Adding numbers in the wrong order
    Why it happens: It can be confusing to remember which number comes first when you're learning.
    Fix: Always start with the first number and count on from there. It's like starting at the beginning of a story.

Parent and carer guide

This is a great opportunity to help your child practice addition in a fun way. Here's how you can support them:
  • Use everyday situations to practice: "You have 3 toy cars and I give you 2 more. How many do you have now?"
  • Let your child use physical objects like counters, blocks, or toys to help them add
  • Practice counting on from the first number: "If you have 4 cookies and get 3 more, start at 4 and count 5, 6, 7"
  • Encourage drawing pictures to show addition problems
  • Don't worry if they make mistakes - that's how they learn!
  • Keep it short and fun. If they get frustrated, take a break and come back later
Five-minute practice ideas:
  1. Count 5 blocks, then add 2 more blocks and count all together
  2. Draw 3 stars, then draw 4 more stars, then count all the stars
  3. Use a number line to add 2 + 3
  4. Play "Addition Race" - say a number and your child says the next number (like 5, then 6, then 7)
  5. Use a deck of cards - pick two cards and add the numbers

What if I don't have objects to count?

You can still add numbers by using a number line, drawing pictures, or counting in your head. You can also use your imagination to think about adding things together.

How do I know if I added correctly?

You can check your answer by counting again, using a different method, or by asking someone to help you double-check.

Why do I need to learn addition?

Addition helps you solve everyday problems like counting your toys, figuring out how many people are coming to your party, or checking how much money you have. It's a skill you'll use all your life!
