Conversion bingo that encourages children to convert between m, cm and mm. Perfect for LK2 learners in Years 3 and 4 as part of their ‘Length and Perimeter’ maths unit. Great for encouraging quick recall in Years 5 and 6 too; especially for children working at a slightly lower than age related expectations. I have used these with my previous Year 3 classes whilst following White Rose’s Length and Perimeter module - they’ve absolutely loved them and I’m sure your children will be no different! The pack contains four teacher question cards and ten children’s bingo cards. I have always laminated both the children’s bingo and teacher question cards to use with whiteboard pens - they last too and can be used year after year. The pack contains 10 children bingo cards so will need to be tripple printed for a class of 30 children. Whilst this does mean that children will have identical cards at any given moment, I’ve found that this only enhances competition and makes for a very noisy classroom too! For wobbly learners, children have also enjoyed working from one card in pairs also.
