Detailed Description Each set of Smart Talk Cards contains 150 crisp, photographic 5"x 5" laminated cards. On the front is a full-color photo with a non-distracting background, while the back contains target vocabulary words for reading along. You can use each card with the Smart Talk Unit to hear the words spoken aloud and use the Learn and Quiz features; or you can use them alone for basic labeling and vocabulary acquisition. Includes classroom objects, colors and shapes, alphabet and numbers, community workers, vehicles and musical instruments.
