There are support examples which lead students step by step through the idea of how to form the fractions to fill in the tree diagram. There are lots of examples and questions where you can cross out the red/yellow counters to help students understand the idea of without replacement as you progress through the lesson(s).

#### GCSE ratio with extension and answers

This worksheet consists of sharing a quantity into a three part ratio, combinations of ratio, then fractions and percentages with ratio. It ends with three extension questions aimed at grade 7+ students. I used this in an observation lesson where I wanted a set 1/2 class to demonstrate a good knowledge of ratio which they’d been learning, but I wanted a good challenge for the most able students to finish with. This worksheet comes with answers written out in a clear way.

All these questions are spaced out so that this can be printed out and students have room to show their working out.
