I don't know about your students, but my students LOVE writing on post-its/sticky notes! I created these graphic organizer for use specifically with post-it notes. Student can respond to fiction or non-fiction text by writing on post-it notes and sticking them on one of the following organizers:
The fiction post-it organizer focuses on story elements: characters, setting, problem, and solution.
The non-fiction post-it organizer has sections for important vocabulary, interesting facts, questions, and connections.
