This interactive floor mat is designed to get children thinking on their feet. The giant caterpillar has a different letter of the alphabet printed on each of its body segments in both lower and upper case. The talking mat helps teach the alphabet, letter sounds, vowel recognition and spelling of 3 and 4 letter words. 4 fun activities are identified with two different skill levels and a clever music mode can turn all letters into musical notes for added fun. A "Step along to the ABC" song is also included. The interactive part of the mat requires 3 AAA batteries (not included) and the overall measurement is 153cm x 82cm. For ages from 3 to 7.
