Factors and Multiples
Key Stage: 2 ★★

This problem will help children become more familiar with factors and multiples. Moreover, a systematic approach is required in order to find all the lines. It will encourage learners to talk to each other, and it provides a good context in which to discuss different methods of approach. It has lots of scope for being opened out and extended through 'what if ...?' questions.
