National Curriculum Maths year 6, but also essential for revision in KS3, and great for lower tiers of Foundation GCSE. 'Multiply simple pairs of proper fractions, writing the answer in its simplest form'.
Guidelines say: 'Pupils should use a variety of images to support their understanding of multiplication with fractions. This follows earlier work about fractions as operators (fractions of), as numbers, and as equal parts of objects, for example as parts of a rectangle.'
Clear step-by-step presentation with questions and answers built in for class discussion and question/answer session. Everything for at least one lesson and some consolidation.
