DragonBox maths: combining numbers

Use age-appropriate, adult-approved play examples to build numbers by joining smaller parts.

Quick answer

DragonBox maths: combining numbers helps children learn how to add numbers together by joining smaller parts to make bigger numbers, using fun, visual, and interactive play.

Learning outcome

By the end of this page, you will understand how to combine numbers using addition and see how this helps in games, real life, and everyday maths. Success signs:
  • You can add two small numbers together (like 3 + 4).
  • You can use objects or pictures to show how numbers join to make a bigger number.
  • You can solve simple addition problems in your head or with help.
  • You can see how combining numbers helps you solve puzzles and games.

Why this matters

Adding numbers is one of the most important skills in maths. It helps you work out how many things you have, how much money you need, how far you’ve walked, or how many points you’ve scored. Whether you’re playing a game like DragonBox, sharing cookies with friends, or counting your toys, combining numbers helps you understand how things grow or come together. It’s also the first step to learning multiplication and more complex maths later on.

How it works

Combining numbers means adding them together. When you have two groups of things, you can count them all together to find the total. This is called addition. Let’s break it down:
  1. Start with two groups of objects (like 3 apples and 2 oranges).
  2. Count all the objects together (3 + 2 = 5).
  3. You now have one bigger group (5 fruits).
This is how addition works in real life and in games like DragonBox. You take smaller parts and put them together to make a bigger number.

Examples you can see

Let’s look at some simple examples of combining numbers using everyday things: Example 1: Counting toys You have 4 toy cars and your friend gives you 3 more. How many cars do you have now?
  • Start with 4 cars.
  • Add 3 more cars.
  • Count them all: 4 + 3 = 7 cars.
Example 2: Sharing snacks You have 5 biscuits and your sister gives you 2 more. How many biscuits do you have?
  • Start with 5 biscuits.
  • Add 2 more biscuits.
  • Count them all: 5 + 2 = 7 biscuits.
Example 3: DragonBox game In DragonBox, you might see two groups of cards. One group has 6 cards, and the other has 4 cards. To solve the puzzle, you combine them to get 10 cards. This is like saying 6 + 4 = 10.

Try it as a mini adventure

Adventure: The Treasure Hunt You are going on a treasure hunt in your garden. You find 3 shells near the pond and then 5 more shells near the tree. How many shells do you have now?
  • Step 1: You find 3 shells.
  • Step 2: You find 5 more shells.
  • Step 3: You add them together: 3 + 5 = ?
  • Step 4: Count all the shells to find the answer.
Try this with your toys or blocks. Put 3 of one thing and 5 of another, then count them all together. You can also do this with your fingers, or draw the shells in your notebook.

Common mistakes

  • Mistake: Thinking 2 + 3 = 6.
    Why it happens: Confusing addition with multiplication.
    Fix: Use objects or fingers to count. 2 + 3 = 5.
  • Mistake: Forgetting to count all the items.
    Why it happens: Getting distracted or not using a strategy.
    Fix: Count each item once, or use a finger for each one.
  • Mistake: Saying 5 + 4 = 9 but counting backwards.
    Why it happens: Not understanding that addition means "more".
    Fix: Use a number line or draw a picture to show the increase.

Parent and carer guide

You can help your child learn how to combine numbers in just a few minutes a day:
  • Play simple addition games with toys, blocks, or food.
  • Ask questions like, "If you have 3 apples and I give you 2 more, how many do you have?"
  • Use everyday situations like shopping or cooking to show addition in action.
  • Don’t worry if they make mistakes – it’s part of learning!
  • Encourage them to count on their fingers or draw pictures to help them solve problems.
