This is a 7-question quiz that can be used as a warm up or as revision. It encourages pairs to work together to find the answer within a given time. Questions cover fractions (quarters and halves), converting grams and kilograms, shapes and multiplication. This was used for a Year 5 class, but could also be suitable for Years 4 and 6. The slides can also be edited if you would like to change the time, names etc to make it more specific to your class.
