This is a set of 30 task cards which give students practice with words that contain the silent letters gn, kn, and wr. Each card has a picture of word that contains the /n/ or /r/ sound. Students have to identify the correct spelling of the word - some words have the silent letters and some do not. An answer key is given, so these task cards can be self-checking. Task cards are a great resource for learning centers, literacy stations, independent practice, and game cards. They can also be projected on a screen to use as a whole class activity.
