Alphabet Zoo is a simple and awesome application which teaches kids to recognize the letters and the sounds of the alphabet. It works with iphone and ipad and it is free. It's ideal for kindergarden kids and young leaners.
Alphabet Zoo is designed and reviewed by educators to teach children letter - sound association, an essential skill for learning to read. More importantly, kids have fun with the animals and the creative sounds without they are even realizing they're learning.
