Subtraction games that make sense
Subtraction is where many children get stuck. Counting backwards is slow and easy to get wrong, and “borrowing” rules mean little to a six-year-old. These free subtraction games take a calmer route in three steps: first see it with counters, then think of it as a missing addition, then practise until the facts stick.
Step 1: take away
Counters fill a ten frame, and some are crossed out. How many are left? This is subtraction at its most concrete: you had 9, 4 went away, 5 are left. The tip always says it in words, so children connect the picture with the sentence.
Step 2: think addition
Here is the big idea. To solve 12 − 8, ask: 8 plus what makes 12? A child who knows 8 + 4 = 12 knows the answer is 4, without counting back at all. Research by Ann Dowker found that only about one in ten young children used this inverse relation on their own, even when it had been taught, so the game names it on every question: think addition. Level 1 stays within 10; levels 2 and 3 go up to 18.
Step 3: mixed facts
Adding and taking away within 20 are mixed together. Mixing makes children read each sign carefully and choose a strategy, and spacing the facts across many questions helps them remember. Show me brings back the counters and the tip whenever needed.
Why this order
Subtraction builds on addition, and addition builds on number bonds. That is why this game starts after addition games and number bonds in our full path, Math Games for Kids. Following one order, rather than many different tricks, is what early math research recommends, and it is exactly what helps a confused child feel confident again.
Short and friendly
Each level has ten questions and takes a few minutes. There is no timer, the buttons are big, and a mistake shows help instead of a red cross. Stars and progress are saved on your device.
Subtraction at home
Put 10 grapes on a plate, eat 3, and ask how many are left. Then ask it the other way: 3 and how many make 10? Little conversations like this, together with a level a day, turn subtraction from a struggle into something your child can explain.
How to play Subtraction Games
- Take away shows counters with some crossed out. How many are left?
- Think addition turns 12 − 8 into 8 + ? = 12. Level 1 keeps numbers within 10.
- Mixed facts mixes adding and taking away within 20.
- A wrong answer shows the picture and the strategy in one sentence. Try again.
Subtraction Games tips
Subtraction is the missing part
10 − 7 asks what goes with 7 to make 10. Children who know their number bonds find subtraction much easier.
Count up, not down
For 13 − 9, count up from 9 to 13: 10, 11, 12, 13, that is 4. Counting up is easier and less error-prone than counting back.
Learn fact families
3 + 5 = 8, 5 + 3 = 8, 8 − 3 = 5, 8 − 5 = 3. Every addition fact your child knows gives two subtraction facts.
Frequently asked questions
Why is subtraction harder than addition for children?
Research shows young children find the link between adding and subtracting (the inverse relation) hard, and they often try to use addition rules on subtraction. Teaching subtraction as thinking addition makes that link explicit.
When should children learn subtraction?
Taking away with objects starts around ages 5 to 6; subtracting within 20 is usually expected by the end of first grade, around age 7.
Should my child learn addition first?
Yes. Subtraction by thinking addition works best once addition within 10 and the bonds of 10 feel easy.
