Seven practice worksheets for Year 5 and Year 6 on factors, multiples, primes and square numbers, with a full checker-verified answer key. English only. Factor pairs, complete factor lists, multiples, primes to 100 (and recall of primes to 19), common factors, the first six common multiples, and square numbers. This pack does not use formal HCF/LCM index notation.
Who it is for: Year 5 and Year 6 (ages 9–11). Use a sheet in a short lesson, for revision or as homework. Allow about 10–15 minutes per sheet.

A second, independent checking program rebuilt every factor list, primality test, multiples sequence and square. Print A4 at actual size / 100%.
AI disclosure: parts of the text and layout were prepared with AI assistance. All graphics are original code-drawn shapes; there are no AI images.
