Subject: Re: How can I teach equivalent fractions?

I reckon pizzas (pies, cakes or tarts as culturally appropriate) are a great way to teach equivalent fractions. Cut a real or virtual pizza into thirds and one into halves. It's obvious that 1/3 + 1/2 is not 2/5. (you could also cut a third pizza into fifths for comparison if you need). Then, having used all that energy on maths, morning tea is ready! This is also a good way of introducing comparisons of the size of different fractions (would you rather have 3/7 or 2/5 of a pizza?.) It might also be a good idea to check your students really understand what 2/3 or 4/5 is. I've blithely "taught" a few kids lots of equivalent fractions and common denominators only to realise they don't really get the whole fraction thing. Good luck!
