I don't think I've seen this pinned here, but this would be a huge hit! :) Sentence Surgery…laminated unedited sentence strips, bandaid strips for ending punctuation, small round bandages for commas and quotations, tongue depressors to mark capitalization, and ‘Emergency Kit’ paper bags w/ red cross on them (to keep surgery supplies).
It would be so cool to have students keep a journal in which they just jot down ideas as they come at random times during the day. I mean, ideas often come at the most inopportune times, and this way they will be on the lookout for stuff they can write about. Then they can refer to it later when they have writer's block.
