The I Can Do Math series uses food, friends, toys, and crayons to help beginning readers learn basic math skills. Large photos and bright colors make each easy, first-step number problem more interesting, as well as easier to understand. A short math quiz ends each volume to reinforce the skills presented and to provide a quick review. If you had ten sandwiches but ate three, how many friends could you feed at a picnic? Foods and friends illustrate simple subtraction problems that take different numbers away from ten.
