Age 5 guide to simple subtraction

Age-appropriate activities, explanations and practice ideas for simple subtraction.

Quick answer

Subtraction is taking away or finding how many are left. At age 5, children learn simple subtraction by taking objects away, counting backwards, or comparing groups. You can use fingers, toys, or drawings to help.

Learning outcome

By the end of this page, you will understand how to subtract small numbers using objects, pictures, and number lines. You will be able to:
  • Take away objects and count how many are left
  • Use number lines to count backwards
  • Compare two groups and find the difference
  • Use subtraction in simple real-life situations

Why this matters

Subtraction is one of the most useful maths skills you’ll ever learn. It helps you know how many sweets you have left after eating some. It helps you understand how much time is left before your birthday. It helps you share toys fairly with friends. In school, you’ll use subtraction to solve bigger problems. In games, you’ll use it to keep track of points. In everyday life, you’ll use it to know how much money you have left after buying something.

How it works

Subtraction is like taking away. You start with a group of things, and then you take some away. The number left is your answer. Step 1: Count how many things you have at first. Step 2: Take some things away. Step 3: Count how many are left. You can also use a number line to help you. Start at the first number, then move backwards by the number you are taking away.

Examples you can see

Let’s look at some simple subtraction examples. Example 1: Taking away toys You have 5 toy cars. You give 2 to your friend. How many do you have left? You start with 5 cars, take away 2, and count the rest. 5 - 2 = 3 You have 3 toy cars left. Example 2: Using a number line You have 7 balloons. 3 pop. 7 - 3 = ? Start at 7 on the number line. Count back 3 steps: 6, 5, 4. So, 7 - 3 = 4. You have 4 balloons left. Example 3: Comparing groups You have 6 crayons. Your sister has 4 crayons. How many more crayons do you have? You compare the two groups. 6 - 4 = 2 You have 2 more crayons than your sister.

Try it as a mini adventure

Adventure: The Lost Treasure Hunt You are on a treasure hunt! You start with 10 coins in your pocket. 4 coins roll under the table. 3 coins are eaten by a friendly dog. 2 coins are lost in the garden. How many coins do you have left? Step 1: You start with 10 coins. Step 2: 4 coins roll away. 10 - 4 = 6 coins left. Step 3: 3 coins are eaten by the dog. 6 - 3 = 3 coins left. Step 4: 2 coins are lost in the garden. 3 - 2 = 1 coin left. You have 1 coin left! You found the treasure!

Common mistakes

  • Mistake: Confusing subtraction with addition. Why it happens: The words "more" and "less" can be confusing. Fix: Use objects or pictures to show taking away, not adding.
  • Mistake: Starting at the wrong number on the number line. Why it happens: Not reading the problem carefully. Fix: Read the problem twice and mark the first number clearly.
  • Mistake: Thinking you must always subtract the smaller number from the bigger one. Why it happens: Not understanding the idea of "taking away". Fix: Use real objects to show what "taking away" means.
  • Mistake: Forgetting to count the number of items taken away. Why it happens: Rushing through the problem. Fix: Count carefully and say the numbers out loud.

Parent and carer guide

You can help your child with subtraction by:
  • Using everyday situations like sharing snacks or counting toys
  • Letting them use fingers or physical objects to show subtraction
  • Practising with simple number lines or counting backwards
  • Reading the problem out loud together and asking questions like "How many did we start with?"
  • Not worrying if they make mistakes – it's part of learning
Tip: Try to make subtraction fun with games, stories, or real-life examples. Keep it short and positive. If your child gets frustrated, take a break and come back later.
