Autumn apple cake v2 Functional Maths tasks

Inspired by Judith White’s autumn apple cake resource (ratios, converting measures, formulae, etc.) this series of open ended tasks focuses on the importance of showing working out and explaining/justifying their conclusions. It also helps students get used to the idea that some maths questions do not have just one “correct” answer.

The theme is baking several cakes for a charity event and making a profit.
You will need Judith’s original recipe (see below) to complete some of the tasks. Fully mapped to the Functional Maths criteria.
