Designed by parents and teachers, this award-winning kit is based on the learning principle of "sight words" -- the first words that kids should learn to recognize without having to sound them out. The word tiles are larger than those of our other kits, so are easy for young fingers to manipulate. For ages 4 and up. This kit contains over 120 magnetic word tiles. Word tile height is .75". Package size is 4.75w x 6h x 1.25"d. Shipping weight is .75 pounds.
