🔟 Make 20 with Ten Frames

About this game

Friends to 20 builds quick recall of the number pairs that make 20. Two ten frames show one number, and students work out the missing friend needed to make 20. Knowing these combinations helps students add and subtract mentally.

Best for: Years 1 to 2

How to play

1. Look at the number shown on the two ten frames.
2. Count the empty spaces or use what you know about friends to 10.
3. Type how many more are needed to make 20.
4. Check your answer and start a new round.

Teaching tips

• Link to friends of 10: if 7 and 3 make 10, then 17 and 3 make 20.
• Turn the voice on so students hear the numbers read aloud.
• Use the worksheet as a quick warm-up or homework task.
