With the PBS Kids Video iPad app, toddlers can watch their favorite PBS television shows with the tap of a screen. Through this free app, PBS posts more than 1,000 television shows and cartoons. Toddlers can browse through programs such as "The Cat in the Hat," "Curious George," "Elmo" and "Arthur" anywhere where they have a strong WiFi or 3G signal. Each week, a "Weekly Pick" is introduced that is designed to teach children reading, math and science. Resources for parents give more information about the shows' intended age group and learning goals, and allow them to add videos to their child's list of favorites.
