I explained to them that they will work in groups by tables and had to decide who is going to have what role. I also talked about each role's responsibilities. The writer (writes down all of the information), the leader (keeps everyone on task), the reader (reads the information), and the reporter (talks to the rest of the class about what they learned).
They had a great time with this, I really think they enjoyed working together and still have their own special responsibility.
You can see in the picture, that the students still had out their bookmarks. Some groups were so excited to use them that they put the bookmarks on the corners of their worksheets or the large picture of the artwork. :)
