I found a great resource to share! ReadWriteThink.org has a great set of student interactives, including graphic organizers such as story maps.
Each map gives prompts to help students be more descriptive, and the maps can be customized to include setting, character, conflict, &/or resolution. That is a great option for differing groupings on the same book.
To explore the interactives on this site go to ReadWriteThink and click on "Classroom Resources" on the tab at the top. There is a lot of great resources there, including this and other "Student Interactives".
If you are already familiar with this site, how do you use it in your classroom? I think I'm in love!
