Forest Phonics is a game, where students learn phonemic spelling by assembling together individual letters, or two-letter combinations (blends & digraphs) that build the word. When kids get the answer correct, they get to see a silly animation. This game was developed by James Barrett, who is a teacher. This version is a shorter version of the one that can be purchased from the App Store.
