FREE for a limited time – ABC Interactive Flash Cards. Kids are introduced to the upper and lower case letters of the alphabet. The letter and a word starting with that letter are pronounced, for example…. A for apple. There is an animated picture to go with each word. The app also has a chalkboard for kids to practice writing the letters. If you are looking to “mix it up”, here is another alphabet app for toddlers. This one, however, does not have stroke-by-stroke instructions for letter formation.
