Sight-word mastery is a snap—with hands-on boards and letter clips children love to use! Kids just grab a board featuring a preprinted sight-word, then attach the clips below to build the word one letter at a time. And with enough letter clips to build all 25 words in each level at once, the sets are perfect for multiple children to work with at the same time. Set includes all 3 levels shown, each with 25 sight-word boards, 67-93 letter clips and an activity guide; boards measure 1/1/2" x 5 1/2
