Happi Full Throttle
Ages: 3 to 8
What it teaches: Social Studies (People and Places), Health (Movement)
Why I recommend it: What child (or adult) wouldn't get into an app for cruising around the house in a firetruck, flying a helicopter as a police officer, driving a race car or submerged in a submarine. Each windshield gives a clear view through your devices camera while you interact with buttons and tools in each vehicle found on the screen. For such a small cost this app both enhances role play activities and gets kids off the couch while using the iPad.
