I use CVC (consonant-vowel-consonant) picture cards all the time in my classroom! These picture cards are a great way to introduce spelling to students. Each picture consists of a 3-letter word (i.e. CAT) so it's easy for students to strecth out and decode the word.
You can use these at a pocket chart center, with magnetic letters, or work with a small Guided Reading group. So many uses for these fun cards!
