About the The Number Detective (Ages 7-11)
Here are our top reasons to buy The Number Detective (Ages 7-11):
- Number puzzles that build mental arithmetic and problem solving together
- Matched to the National Curriculum for maths in Years 3 to 6, ages 7-11
- Puzzles use real number language: factors, multiples, primes and square numbers
- Detective-style clues where children test ideas and rule numbers out
- A printed puzzle book one child can work through alone
Your child is in Years 3 to 6, and this is maths practice that feels like a puzzle to solve rather than a page of sums.
The clues here cover the number work your child meets in class, from factors and multiples to primes and square numbers. Each puzzle asks them to think, not just calculate. A Year 7 child who never felt sure with number properties can go back over them here without it feeling babyish.
This printed puzzle book gives your child a set of clues and a mystery number to pin down. One page asks them to find a semi-prime, then join points to reveal a shape. Another sends them through a maze along two routes of calculations to find matching numbers at the centre.
Because the puzzles reward patient reasoning, your child slows down and checks. That habit sits behind the problem solving the KS2 SATs ask for, and behind confident mental arithmetic in any primary classroom.
