The Alphabet Apple by V-Tech is designed to let preschoolers take a good bite out of learning their letters. Insert two AA batteries (not included) into the sturdy-plastic, portable unit, and youngsters can slide the "worm" in the apple to select one of five settings. The first four settings instruct kids in letter recognition and sounds, complete with letter-finding games using the push buttons. A fifth option offers nine different melodies that play (regrettably, at a nonadjustable volume) at the press of a key. With its colorful, kid-friendly design, the Alphabet Apple provides the seed for a solid core of learning.
