Maths for 7 year olds: what to practise at home
In England, a 7 year old is either at the end of Year 2 (the last year of Key Stage 1) or starting Year 3. It is the age when counting turns into calculating: two-digit numbers, the first times tables and simple fractions.
Below is a checklist of what most 7 year olds work on at school, a few questions to try together, and a free game set to the right level.

What most 7 year olds can do in maths
Children vary a lot at this age, so treat this as a guide to what school is working on, not a test. By the end of Year 2, most children are learning to:
- Read and write numbers to 100. Know what each digit in a two-digit number is worth, and find 1 or 10 more or less than any number.
- Count in steps. Count in 2s, 3s and 5s from 0, and in 10s from any number, forwards and backwards.
- Know number bonds to 20. Facts such as 13 + 7 = 20 and 20 − 6 = 14, and use them for bonds to 100 such as 30 + 70.
- Add and subtract two-digit numbers. A two-digit number and ones, two two-digit numbers, and three one-digit numbers, checking with the inverse.
- Use the 2, 5 and 10 times tables. Recall them, spot odd and even numbers, and see multiplication as equal groups.
- Find simple fractions. 1/2, 1/3, 1/4, 2/4 and 3/4 of a shape or a group of objects, and see that 2/4 is the same as 1/2.
- Money and time. Combine coins to make an amount in pounds and pence, and tell the time to five minutes.
Maths questions for 7 year olds
Try these out loud, on paper or with real objects. Each one matches a point from the checklist.
1. What is 10 more than 47? What is 10 less?
Answer
57 and 37. Only the tens digit changes.
2. Count back in 10s from 93. What are the next three numbers?
Answer
83, 73, 63.
3. You have 20 stickers and give 6 away. How many are left?
Answer
14, because 14 + 6 = 20.
4. 35 + 24 = ?
Answer
59: 30 + 20 = 50, 5 + 4 = 9, and 50 + 9 = 59.
5. There are 4 bags with 5 apples in each. How many apples?
Answer
20, because 4 × 5 = 20, or 5 + 5 + 5 + 5.
6. A pizza is cut into 4 equal slices. You eat 2. What fraction is left?
Answer
2/4, which is the same as 1/2.
Games that match age 7
For a 7 year old in Year 2, choose “Year 2” as the practice level (the button above sets it); for one in Year 3, choose “Year 3”.
- Number Grove (addition): adding, with counters for small sums and hints that count on or split a number.
- Subtraction Shores (subtraction): taking away, with each answer checked by adding back.
- Multiply Mountain (multiplication): equal groups of counters, opening from Year 3 (age 7+).
- Fraction Falls (fractions): halves, thirds and quarters of shapes, opening from Year 3 (age 7+).
Not covered yet: place value, money and time. A handful of real coins and a clock with hands are the best tools for those.
What parents see
Each stage is five questions, and four right completes it. The progress page shows which stages your child has completed in each world and their recent scores; the parent report for the Moonwell story also separates guided practice from independent answers. Everything stays in this browser, with no child account.

Questions parents ask
How much maths practice does a 7 year old need at home?
Five to ten minutes on most days is plenty. Short and regular beats long and occasional, and talking about maths in everyday life (shopping, cooking, clocks) counts too.
Are there SATs at age 7?
The Key Stage 1 SATs at the end of Year 2 have been optional for schools since 2023/24, so many children no longer sit them. Teachers still assess progress through the year.
My 7 year old finds maths hard. Where should we start?
Start with number bonds to 10 and 20 and counting in 2s, 5s and 10s. Confidence with those makes everything else in Year 2 and Year 3 easier.
Is Clarendium free?
Yes, every game is free to try in the browser now. Memberships are planned but not open; the waitlist asks only for a parent’s email.
