Print out one (or all) of these "frames" and use them to practice CVC speech words. Simply slide the sheet into a sheet protector and write one sound in each circle using a dry erase marker. After the child says the word, erase one of the sounds and write in another. So if you're working on final /n/, you could do pan, man, can, ran, ban, etc. Then switch your vowel and do pen, ten, men, den, hen, etc. This is a great way to work on speech, phonemic awareness, and early reading skills at the same time.
