Each of these books introduces a basic counting concept and follows one method consistently to teach it. Spreads devote three or four sentences to a number. In four of the books, an addition or subtraction equation shows how the result can be achieved, and, in all, a number line along the bottom highlights the relevant digit. Students will love these titles because there are plenty of friendly creatures to count, and the books make it easy to perform the task. Count the Critters is an excellent choice for early elementary classrooms.
