In this fun exercise book, your child will quickly learn to calculate with sizes and weights! The exercises follow the school curriculum, so that your child can continue to practice at home what he or she has already learned at school: calculating with the euro, calculating perimeter and surface area, working with length, volume and weight, etc.
The more your child practices, the smoother it will go. As a result, your child will understand the lessons better and will always be one step ahead!
