Big Lauri® crepe rubber letters spell lots of learning activities. Each letter comes in a puzzle frame that links only to the succeeding one, making sequences as easy as A-B-C. Or hop, skip, and jump from letter to letter and learn the alphabet frontward and backward. Kids also can lace the letters to help reinforce letter shapes. Each set includes 26 4″ tall letters plus frames. When you combine the uppercase letters with the lowercase letters, kids can match A to a and B to b but not A to b.
