Ratio and proportion is such a hands on topic it deserves more than a lesson on recipes for spag bol and pancakes. So why not try out some cocktails!
This has to be one of my favourite lessons, ideally ran over two sessions. In session one you discuss recipes and strategies for working out different quantities (example of Pomegranate Paradise is below), students then complete the four modelled examples on this sheet. In the next session students use the examples for inspiration and make up their own cocktail, they have to work out the cost of making 100 and the % profit (worksheet here). Then they get to make it and sample their hard work! You will need to borrow some measuring jugs from food tech and make a trip to home-bargains for some cheap ingredients.
My students loved this lesson and even stayed at break to make another one! There really is a lot of Maths involved, they have to work out proportions, convert measures, calculate cost, profit and then interpret scales and they certainly won’t be forgetting it in a hurry!
