Practice that builds confidence
Building the idea of ten
These Grade 1 addition worksheets focus on number bonds with a total of 10. Children practise seeing 10 as two parts, such as 6 and 4 or 9 and 1, so addition facts become easier to recall and explain.
The printable activities include visual bonds, missing-part problems, and related addition sentences. They are designed to move children from counting objects toward knowing the pairs that make 10 with confidence.
Number bonds show that a whole number can be split into parts. On these worksheets, the whole is always 10, so children repeatedly meet the pairs 0 and 10, 1 and 9, 2 and 8, 3 and 7, 4 and 6, and 5 and 5. This supports Grade 1 addition because children learn that the same total can be made in different ways.
Practice progression
Children may begin with pictures or filled-in bond models, then move to blanks such as 10 = 6 + __ or __ + 3 = 10. Some pages connect the bond to an addition sentence, helping children understand that a diagram, a number pair, and an equation can all show the same relationship.
A simple parent routine
At home, choose one page and keep ten small objects nearby, such as coins, buttons, or cereal pieces. Ask your child to build one part, then hide or move the rest and say the missing part aloud. After a few hands-on examples, have your child complete the matching worksheet problems and read each full number sentence: “7 and 3 make 10.”
Classroom uses for teachers
Teachers can use these printables for morning work, addition centers, small-group reteaching, or quick checks before moving into larger addition strategies. They also work well with ten-frames, counters, and partner practice where one student names a part and the other names the complement to 10.
Common errors to watch for
Some children reverse the whole and a part, writing 10 as a part instead of the total. Others count all objects every time instead of using a known pair. Watch for near-misses such as 6 and 5, especially when children rush. Encourage them to check by counting both parts together or by comparing with a ten-frame.

Why iBloom worksheets help
The activities give focused practice on one important Grade 1 addition skill instead of mixing too many goals at once. Clear models, repeated totals, and missing-number formats help children recognize patterns. A helpful child-friendly strategy is: “Start with the part you know, then think what number finishes 10.”
Helpful answers
Frequently asked questions
What are number bonds that make 10?
They are pairs of numbers that add up to 10, such as 1 and 9, 4 and 6, or 5 and 5. Children use them to understand part-part-whole relationships in addition.
Why is making 10 important in Grade 1 addition?
Knowing the pairs that make 10 helps children solve addition problems more efficiently. It prepares them for strategies like adding 8 or 9 by making a ten first.
Should my child memorize the number bonds to 10?
Yes, but understanding should come first. Use counters, fingers, or ten-frames so your child can see the two parts of 10 before working toward quick recall.
How can I help if my child keeps guessing the missing part?
Ask your child to build 10 objects, separate the known part, and count what remains. Then repeat the same pair in a number bond and an addition sentence.
Can these worksheets be used with ten-frames?
Yes. A ten-frame pairs naturally with number bonds to 10 because children can see filled and empty spaces as the two parts that make the whole.

Yes. You can preview it for free and use the printable worksheet for home or classroom practice.
