These three sets of self-checking dry erase cards actively involve students in substituting phonemes to make new words. With CVC cards, players change one letter at a time in four steps to turn, for example, pig into dog. The long and short vowel sets with blends and digraphs involve changing one or two letters at a time in five steps. Students record the words on the cards or on the reproducible recording sheets found in the Guide. Use the cards with a projector to engage the whole class. A great daily word work activity!
