A great wooden puzzle that includes both the alphabet upper and lower case letters. The pictures under the pieces reinforce the learning of the sounds of the letters. For instance, a butterfly for capital ?B and a bowling ball for lower case b are found under each of those letters. Letters are slightly raised above their opening for easy removal. Builds letter recognition and sounds, strengthens fine motor skills and visual perceptual skills (mental rotation of how the piece fits) while the child is having fun!
