There are 9 individual student Alphabet Sound charts in this product. (They correlate with the Alphabet Sound Wall Chart in my store.) Each chart has is different each month. There are a total 234 picture sound cards for the Alphabet. I practice the Alphabet Sound chart each day and have noticed a big difference with my kiddos by doing this each day in letter knowledge and sound association. I have listed a variety of ways to practice the letters and sound cards. There is key for all the picture card names.
