Adding Ten Practice Activities
Printable adding ten worksheets help children build quick addition fluency by using the place-value pattern of increasing the tens digit.
Practice that builds confidence
Understanding the add-ten pattern
These Adding Ten practice activities help children see that adding 10 is not just another counting task. They practise adding 10 to given numbers, noticing how the number moves to the next ten while the ones digit usually stays the same.
The printable worksheets include focused addition drills, number-pattern practice, and quick-response activities. They are useful for maths revision at home, class practice, warm-ups, and building confidence before larger addition facts.
Adding ten builds an important place-value idea: when 10 is added to a number, one more ten is made. Children learn to connect facts such as 23 + 10 = 33 and 46 + 10 = 56 with the tens and ones in the number, rather than counting on one by one. This skill supports later work with mental maths, two-digit addition, and number patterns.
How the practice progresses
The worksheets keep the focus narrow so children can gain fluency. Early questions may use clear two-digit numbers where the ones digit stays unchanged, helping learners notice the structure. As practice continues, children answer mixed addition facts, complete missing sums, and recognise repeated jumps of 10. The goal is speed with understanding, not memorising isolated answers.
A simple parent routine
At home, ask your child to read the number aloud, say how many tens it has, then add one more ten. For example: “34 has 3 tens and 4 ones; adding 10 gives 4 tens and 4 ones, so 44.” After a few written questions, play a quick oral round: you say 18, 27, 52, and your child replies with the number that is 10 more.
Classroom uses for teachers
Teachers can use these printables as maths drill sheets, morning work, revision pages, small-group fluency practice, or quick checks after teaching tens and ones. They also work well in centres where children match equations to answers, sort correct and incorrect add-ten facts, or explain the pattern to a partner.
Common errors to watch for
Some children add 1 instead of 10, writing 35 + 10 = 36. Others change both digits, especially if they are still relying on counting. Encourage them to look at the tens place and ask, “Which digit changes?” If a number such as 90 is included, check that children understand moving to the next hundred.

Helpful answers
Frequently asked questions
What skill do these Adding Ten worksheets practise?
They practise adding 10 to numbers and recognising that the tens digit increases while the ones digit usually stays the same.
Should children count on by ones to solve these questions?
Counting on can work at first, but the aim is to help children use place value. They should learn to add one ten instead of counting ten single steps.
How can I explain adding 10 to my child?
Use the phrase, “Keep the ones, add one ten.” For example, in 28 + 10, the 8 ones stay, and 2 tens become 3 tens, so the answer is 38.
Are these worksheets useful for mental maths practice?
Yes. Adding 10 is a key mental maths skill because it helps children see number patterns and prepare for adding larger two-digit numbers.
How can teachers use these worksheets in class?
Teachers can use them for warm-ups, maths drills, small-group support, independent practice, or quick checks after teaching tens and ones.
Is this adding ten worksheet free?
Yes. You can preview it for free and use the printable worksheet for home or classroom practice.
