Ways to make ten

Read with an adult. Take your time. You can say, point, draw or write your answer.

Let's look together

Ten can be made from two parts. The pairs are number bonds.

A ten-frame helps us see the missing part. Count the full spaces, then the empty spaces. Together they always make ten.

7 filled and 3 empty make 10
Look, point and talk with your adult.

Watch how I do it

Seven spaces are full. Three are empty. Seven and three make ten: 7 + 3 = 10. Also, 10 − 7 = 3.

Your turn

Six spaces are full. How many more counters fill ten spaces?

Have a go before opening the answer.

Let's check together

Four. 6 + 4 = 10.

Try it away from the page

Find all pairs making ten. Swap the two parts. Tell someone a matching take-away fact.

Adult notes · prerequisites, safety and coverage

Prerequisite: addition and subtraction within ten. Include 0+10 and revisit facts through objects and talk, not timed pressure.

Use large counters, blocks and paper before symbols. Revisit a lesson until the child can show and explain the idea. Numbers grow from 0–10 to 20, then 100; these pages are not a one-sitting course.

These are teaching introductions, not a claim of mastery. Open the subject's coverage map and limits.
