For toddlers who are eager to learn, try Old MacDonald, Itsy Bitsy Spider, and Wheels on the Bus. The creative team at Duck Duck Moose has created - and delivered -- exquisite lessons of cause and effect with a charming and whimsical touch.

Poke or slide things on the screen to see what happens. These pitch perfect instructions invite little hands to explore and learn as they see and hear the words of the classic childhood song.

But watch out for the flying paper airplane. And yes, global toddlers can here the song sung in a variety of languages.
