Heads up, parents. Everybody's favorite bald-headed boy is now on Android. Caillou's World (for those of you without kids, Caillou is a popular kids show on PBS) is intended for children ages 2-5 and helps with reading, spelling and phonics. The child spots a highlighted item in a picture and taps it, and then has to choose which letter the item starts with, all while associating the picture with the sound of the word, and the spelling.
The app works well enough on a large smartphone, but it's even better on a tablet, with more screen real estate. Caillou's World is $2.99 in the Android Market. We've got download links after the break.
