My year 8’s are just finishing a unit on ratio. Their assignment included working out ingredients needed to make a “Harriet Hedgehog” and a “Calculator” cake. You can check out the assignment at hermathness.
I added an extra ingredient (excuse the pun), that if they baked a hedgehog or calculator cake they would be rewarded with 2 extra grades. Three students took up the challenge. Shown below are their cakes which they shared with their class!
