The deluxe activity cards box measures 6.25" X 8.34" X 1.34", and contains 26 sturdy cards with rounded corners. A blue marker is also included. The cards measure 5" X 8" and are double-sided. Elmo and friends are practicing their ABCs, and your child will learn right along with them by using these deluxe activity cards. Each of the 26 big, sturdy cards deals with one letter of the alphabet. On the front, the letter is learned - both uppercase and lowercase. On the back, words that start with said letter are given. And on each side, bright illustrations of your child's favorite Sesame Street characters bring the lessons to life. With over 40 years of programming and 118 Emmy awards (more than any other television series), Sesame Street - featuring cute and cuddly Elmo - continues to grow and delight with every episode.
