Elmo and his Sesame Street friends invite girls and boys ages 1 to 3 to learn about numbers, shapes, the alphabet, opposites, and more. Full-color illustrations filled with charming details turn playtime into learning time in colorful scenes of lovable characters in the biggest flap book ever! Toddlers can lift alphabet blocks to find a word beginning with each letter, open doors and windows on Sesame Street to count objects from one to ten, lift flaps that reveal opposites, and help Elmo find his teddy! The sturdy flaps—10 to 26 per double-page spread—are made to stand up to the repeated wear and tear little ones are sure to inflict with lots of lifting, looking, seeking, and finding!
