This super special alphabet plus+! letters helps littles develop strong letter recognition and early spelling skills. This kit comes with every letter plus the duplicates seen in the top 100 sight words adapted from the Fry and Dolch sight words list (A, D, E, F, G, L, M, O, P, T). "M" is actually not part of that list but what kids do not want to be able to spell "mom" or "dad" when practicing their favorite words?!
