This is a nice idea for a starter on working out percentages of amounts. Students have to calculate a percentage given the number of squares of chocolate. All the percentages are fairly straight forward and would not need a calculator. They then get to eat this piece if they are right. Some students might cotton on that the number of squares in the next question gives them the answer to the current question so it would be worthwhile adding an animation to cover the next questions up! Thank you for sharing, I will certainly try this.
