The children first worked out how much squash and water would be needed to make their drinks in the different ratios, for example to make 200ml of ‘drink’ in the recommended ratio 1:9 they’d need 20 ml of squash and 180 ml of water.
They had great fun making and tasting their drinks and some even pushed themselves to introduce a third ingredient of blackcurrant squash, working out how to share 200ml into 3 parts!
The children were all impressed that this is Maths they do almost every day anyway and have now been challenged to find other ways they use ratio in proportion in every day life…can you think of any ways?
