Fractions of numbers / ratio and proportion / bar models / reasoning / problem solving

Two pages of bar model puzzles for upper KS2 or KS3. Each puzzle has three parallel bars, of different lengths, divided in different ways. By starting from the one value given, students need to use a range of strategies to find the answers in the other bar models. Steady progression of questions, gradually becoming more difficult. An ideal homework for year 6, more able year 5, or support in year 7-9.
