Learning-friendly Old MacDonald
More than 5,000 kid-friendly applications exist for iPhones. Where to start? Claire Green, president of Parents' Choice Foundation, offers her picks. All are available for under $5 — many of them for 99 cents — at Apple's App Store.
Toddlers: Old MacDonald, Itsy Bitsy Spider and Wheels on the Bus, all by Duck Duck Moose, offer colorful, whimsical lessons of cause and effect that just beg fingers to tap on the screen to move the farmer's tractor forward or the spider up and down. Tickle Tap Apps bundles five games in which little hands can tilt the iPhone back and forth to play shape and sound games.
Elementary: Highlights for Children adds digital fun to the magazine's iconic hidden-picture puzzles. Find objects embedded in the black-and-white picture and turn them to color.
Tweens and teens: Take finding skills to the next level with I Spy Spooky Mansion. Wannabe drivers can try the Rush Hour app, based on the beloved board game; maneuver the red car out of a mind-challenging gridlock.
