Practice is the most important way that children develop the skills they need to be successful learners. This wipe-off book allows them to do just that! By completing the book’s colorful exercises, your child will learn to subtract numbers 1 through 10, as well as critical thinking skills and how to follow directions in both English and Spanish. Then he or she can practice over and over again to reinforce subtraction skills. An answer key on the inside back cover allows your child to check his or her work and to recognize and correct mistakes. Use this book at home or on the go to help your child get ahead on the learning curve!
