In Word World, set in a lush landscape filled with funny barnyard animals, the messages are clearer: because each animal is graphically spelled out, kids can watch as the letters C-A-T form that carnivorous mammal creature. Even the scenery gets in on the act- a barn, a tree, a splash in the lake. When animals take time to build a word (always a moment of great expectation and jubilation), you can actually witness the little wheels working in the viewers' heads. After just one viewing, a 4-year-old who's always struggled with her letters volunteered to spell a new word: B-O-X.
