This is one very terrific program to aid a child to learn Phonics. The child hears the sound as he/she follows with their finger. So that involves 3 of the senses: Seeing the letter, hearing its sound, and following the letter with their finger gets motor skills involved. The more involved, the greater chance the youngster will remember the sound made by the letter. Its a great program for teaching Phonics.
