Number bonds, or addition facts are important for young children's mathematical understanding. These are simple sums that we learn to recognise, almost without thinking about it. The same applies to simple subtraction. This book has 140 simple sums, devised to help young children to learn and practise some of the number bonds. Use the number strip at the top of each page to help your child to count forward or backwards. The pages are laminated and can be used over and over again.
