Some sounds are made by putting two letters together. Mortimer the Teddy Bear plays a flute. He tells us it "begins with the letters fl." Then kids get to guess which object on the next page begins with "fl," too. Fly? Slide? Flower? On every page there are letter combinations and bright glossy photos of matching objects. Mortimer teaches by using items that are familiar to children. There are photos of a train, crown, scarf and more. The Mortimer books always include a glossary/index and a list of helpful videos.
