A very versatile product which can be used for anything from simple addition of single digits up to subtraction, multiplication and division of 3 digit numbers. I have personally used this product with children aged between 5 and 9 years of age. I print and laminate these and use with dry wipe markers. Write any number in the centre square and the children have to come up with various calculations which would equal that answer. Excellent for providing challenge for more able pupils. Can be used as a fast finishers activity. Download once and use for years to come.
