Mastering vowel sounds is a snap—with hands-on picture boards and letter clips kids can’t resist! Students just grab a board, then snap the clips right on it to build the word that matches the picture. And with enough letter clips to build all the words at once, the set is perfect for multiple children to use at the same time! You get 20 picture boards, 58 one-letter clips, 10 two-letter clips and a guide. Boards measure 2 1/2" x 4 1/2".
