450+ Color (or black and white) flash cards! Some ideas on how you can use them: Small group, put on a ring for extra couple minutes in class, split them up by vowel or mix together, send home for practice, have students use them if they finish early, post outside your door for a secret daily word, etc.
These do not just include magic E words but all other letter combinations that create long vowel sounds.
