A set of 13 worksheets providing a variety of questions about finding and using prime factors. The questions try to encourage students to understand how prime factors can be used to explore the properties of numbers. Venn diagrams are used to calculate the lowest common multiple and highest common factor and the sheets help students see why the Venn diagram works. They are suitable for revision, reinforcement and extension work on prime factorisation.
There is a lot of emphasis on being able to explain what key maths vocabulary means e.g. words like factor, multiple, prime.
Most of the sheets have spaces for the answers to be written on. There is one sheet which contains similar questions with no working out space. Answers are provided.
