(Grades Pre-K & up). Our new magnetic letters and numbers are the best on the market with larger, stronger magnets for a “sure stick.” Letters are shaped accurately with correct proportions, and assortments come with more of the letters you need most (extra vowels a, e, i, o, u, and consonants b, l, m, r, s, and t). Letter sets include punctuation marks, and number sets include math symbols. Jumbo pieces are 21/2" tall for handling ease and tactile feedback for young children learning basic skills (regular pieces are 11/2" tall). Each set comes in a durable, stackable tub with brightly colored plastic lid for convenient self-storage. Multicolored sets come with red, blue, green, yellow, orange and magenta pieces.
