This KS3 Number Properties test paper is a complete end-of-topic assessment for Years 7 to 9. 20 questions (40 marks) build gently from easier to harder, finishing with a short stretch section for confident mathematicians.
What's covered
Factors, multiples, prime numbers, square and cube numbers, and powers. Then writing numbers as products of prime factors in index form, and finding the highest common factor (HCF) and lowest common multiple (LCM), including by the prime-factor method. The final questions are worded HCF and LCM problems, such as tiling a room with the largest possible square tiles.
What's included
- A cover page with space for name, class and date
- 20 questions worth 40 marks, graded from easier to harder, finishing with a short stretch section
- Ruled working space under every question, because method marks matter
- A complete mark scheme written in plain English — the working is shown for every multi-step answer, so you can mark with confidence even if maths is a distant memory
The mark scheme starts on its own page, so you can print the test without the answers. One print-ready A4 PDF, 11 pages — it prints cleanly on ordinary A4 at home.
