Sums To 10 Practice Activities
Printable maths drills that help children recall addition facts with totals of 10 using number pairs, equations, and missing-addend practice.
Practice that builds confidence
What children learn
Sums to 10 practice builds quick recall of the addition facts that make exactly 10, such as 6 + 4, 9 + 1, and 0 + 10. Children practise seeing 10 as a total made from two parts, not just as the next number after 9.
These printable activities include focused addition drills, number-pair practice, equation writing, and missing-number questions. They are useful for home revision, class maths practice, and building confidence before children move on to larger addition facts.
This collection focuses on addition facts where the sum is 10. Children connect addends and totals using vocabulary such as add, plus, equals, sum, total, pair, and number bond. The aim is not only to calculate each answer, but to recognise pairs that go together: 1 and 9, 2 and 8, 3 and 7, 4 and 6, and 5 and 5.
How the practice progresses
Worksheets can begin with straightforward facts like 7 + 3 = 10 and then move to mixed order, such as 3 + 7 = 10. Missing-addend questions, for example 6 + __ = 10, help children think about the unknown part. This progression supports mental maths because children learn that the order of addends can change while the total stays the same.
A simple parent routine
At home, choose one worksheet and first ask your child to say the number pairs aloud. Then let them complete the page independently. After checking, ask them to correct any errors by drawing dots, fingers, or a quick number bond. Finish with a short oral round: say a number from 0 to 10 and ask, What goes with it to make 10?
Classroom uses
Teachers can use these pages for maths drills, morning work, small-group support, or quick review before addition lessons. They also work well in centres where children sort or write facts that make 10. For pupils who need extra support, the same facts can be shown with counters, ten-frames, or number lines before moving back to written equations.
Common errors to watch for
Some children count on accurately but stop one number too early or too late. Others mix up facts that make 9 or 11, especially with 4 + 5 or 6 + 5. In missing-number questions, children may copy the answer 10 into the blank instead of finding the missing addend. Encourage them to check whether both parts together really make the total.

Why iBloom worksheets help
The worksheets keep the focus narrow: every question reinforces sums to 10. This repeated, purposeful practice helps children notice patterns instead of treating each fact as a new problem. A child-friendly strategy is: start with the bigger addend, count up to 10, and say the missing part. For example, from 7 count 8, 9, 10, so 3 is the partner.
Helpful answers
Frequently asked questions
What does sums to 10 mean?
It means addition facts where the total is exactly 10, such as 2 + 8, 6 + 4, and 10 + 0.
Which facts should children know for sums to 10?
Children should practise all pairs from 0 to 10 that make 10, including 0 + 10, 1 + 9, 2 + 8, 3 + 7, 4 + 6, and 5 + 5, in both orders.
How do missing-addend questions help?
Questions such as 7 + __ = 10 help children understand that addition is made of parts and a whole. This builds stronger mental maths than memorising isolated answers.
Can these worksheets be used before number bonds to 20?
Yes. Confident recall of pairs that make 10 gives children a useful base for adding larger numbers, bridging through 10, and later learning number bonds to 20.
What should I do if my child keeps guessing the partner number?
Use counters, fingers, or a ten-frame. Show the known addend, then count the empty spaces needed to reach 10. After a few examples, return to the written question.
Is this sums to 10 worksheet free?
Yes. You can preview it for free and use the printable worksheet for home or classroom practice.
Can I download this sums to 10 worksheet as a PDF?
Yes. Use the worksheet download option to save a printable PDF, or print the worksheet directly from the page.
