Hi all, I'm doing a graphing activity for 2nd grade. I want to make collaborative group of 4 or 3 where each student will have a role. Each group will collect data and make a graph. Since it is a collaborative effort, I'm wondering what kinds of roles each student should have. So far I have the Interviewer/Tally Recorder, Presenter. I'm not sure what to name the other two roles. For example the person who will write and color in the graph. Thanks!
