Dora ABCs Vol 1 is a great way to introduce your child to letter sounds. This app uses finger tracing to expose your child to the sounds, formation and names of each letter of the alphabet. The sound each letter makes is reinforced as they are tracing, a really meaningful feature. The game in the app has your child tilt the device to get bouncing acorns into spaces on the screen, not an easy task. Multiple children can log on. Child progress through the three levels (upper case, lower case and both) can be viewed from the player page.
