These are the blocks that light up to teach toddlers about shapes and colors and older kids about reading, writing, and arithmetic. The set consists of a pegboard and three dozen 1" blocks that emit a colorful glow or mesmerizing flash when plugged into the board or another block. One dozen displays shapes, numbers, and basic mathematical signs; another shows the letters of the alphabet; and the final 12 are emblazoned with simple words such as “red”, “dog”, and “big”. Toddlers can stack blocks into towers then graduate to counting and reciting their ABCs, while older children can compose sentences, practice their times tables, or even solve basic equations. The set can also be used to play 39 different games, including tic-tac-toe and checkers. The board doubles as a storage container. Requires three AA batteries. Ages 3 and up. Box: 22" L x 4" W x 15 1/2" D. (5 lbs.)
