A quick document to use as a JIGSAW activity for a small or large group of students. You can edit this document to fit your needs!
I use this with my APUSH students to help them gather large amounts of information in a short period of time, which helps with the reading load.
Each student is responsible for doing their own research the night before (What are three major events that caused the Civil War?). The next class period I "share" the document via Google Docs (you can probably do this in other ways too) and they all contribute the information they compiled so that it creates one document for all to use.
These kind of worksheets process information quickly and then we can discuss their findings together as a class, adding notes from the discussion if necessary.
