The Connecticut State Department of Education defines dyslexia as resulting from a significant deficit in phonological processing. Put simply, phonological processing is the ability to recognize and manipulate the sounds that make up our language. That’s why babies start out saying “nana” instead of “banana” as they are developing their phonological awareness (they are also learning how to use their lips, teeth, tongue, etc. to make the precise sounds they want). It’s also why we do lots of clapping games and rhyming songs in preschool.
In an OG lesson, the first step is the drill pack. This is a pack of cards containing all of the sounds the student has previously learned. The instructor shows the student the card and the student names the sound. NOT the letter! We’re teaching the student the correspondence between the letter(s) on the card and the sound(s) they make. For example, if I show a student a card with the letter “c” on it, I want them to tell me the hard sound (candy) and the soft sound (Cindy).
