Number Bonds Sum 10 Practice Activities
Printable Class 1 maths activities help children practise number bonds that make 10 using pairs, missing parts, and visual addition models.
Practice that builds confidence
What children learn
These Class 1 maths worksheets help children build quick recall of number bonds with sum 10, such as 6 + 4, 7 + 3, and 10 + 0. Children practise seeing 10 as two parts, not just as a number reached by counting one by one.
The printable activities use clear addition formats, part-part-whole models, matching tasks, missing-number questions, and visual supports such as ten-based arrangements. They are useful for daily addition practice at home or in the classroom.
Number bonds to 10 are the pairs of numbers that join to make 10: 0 and 10, 1 and 9, 2 and 8, 3 and 7, 4 and 6, and 5 and 5. In Class 1 addition, this skill helps children move from counting every object to recognising useful pairs. It also prepares them for mental maths, subtraction, and later addition across 10.
How the practice progresses
The worksheets begin with familiar combinations and visual cues, then move towards missing parts such as 6 + __ = 10 or __ + 3 = 10. Children may match pairs, complete number bonds, write addition sentences, or identify the missing addend in a part-part-whole model. Seeing the same bond in different ways helps them understand that 4 + 6 and 6 + 4 both make 10.
A simple parent routine
At home, start with ten small objects such as buttons, rajma beans, or crayons. Ask your child to split them into two groups and say the bond aloud: “2 and 8 make 10.” Then complete one worksheet section together. After each answer, ask, “How do you know?” This keeps the focus on understanding the pair, not only filling blanks.
Classroom uses
Teachers can use these pages for maths warm-ups, addition centres, partner practice, or quick revision before teaching larger sums. One group can work with counters while another completes the printable page. The worksheets also make it easy to spot which children know the full set of bonds and which still rely on counting from 1.
Common errors and a child-friendly strategy
Children often reverse the idea and write any two numbers they see, forget the bond with 0, or count inaccurately when finding the missing part. A helpful strategy is “think of 10 as a full box.” If 7 spaces are filled, 3 are empty; so 7 and 3 make 10. Encourage children to check by counting both parts together or by naming the partner number.

Helpful answers
Frequently asked questions
What are number bonds to 10?
Number bonds to 10 are pairs of numbers that add up to 10, such as 1 + 9, 2 + 8, 3 + 7, 4 + 6, and 5 + 5.
Why are number bonds to 10 important in Class 1 maths?
They help children understand addition as combining parts, build mental maths fluency, and prepare for subtraction and addition with larger numbers.
Should my child memorise all the pairs?
Quick recall is helpful, but children should first understand the pairs using objects, drawings, or part-part-whole models before memorising them.
How can I help if my child keeps counting from 1?
Use 10 objects and cover some of them. If 6 are showing, ask how many are hidden to make 10. This helps your child think in partners instead of recounting everything.
Do these worksheets include missing-number practice?
Yes. Children practise complete addition facts as well as missing parts such as 8 + __ = 10 and __ + 4 = 10.
