Mortimer is a busy little teddy bear playing with his toys. And all these toys have letters in the beginning, middle, and end. Learning with Mortimer is fun as kids get to match the right sounds to pictures. What ends with the letter t? Can? Cat? Bed? Mortimer teaches by using items that are familiar to children. Each page is full of bright glossy photos of toys, food, and clothes. The Mortimer books always include a glossary/index and a list of helpful videos.
