After the students have learned about the "sh" and "ch" digraphs, I put this in literacy centers for the students to review. The students work on this independently. To set up, the teacher cuts up the labeled images, laminates them for extra reinforcement, and tapes them around the room. The students then get a clipboard and the writing page. They go on a word hunt and sort the words into the correct column based on the digraph in the word.
