A book full of entertaining activities and expert math monsters that will help children practice subtraction using the numbers from 0 to 10. The original exercises are inspired by such fun contexts as a fair, a monster banquet or the launch of a rocket. The book's laminated pages and erasable ink pen allow children to erase if they make a mistake, or erase at the end and start over whenever they want.
