Are you looking for a way to keep your small groups accountable for their work and time on task without having to constantly remind them of the requirements?
The Small Group Points Sheet works much like a rubric, allowing the teacher to clearly state expectations ahead of time. It also provides a checklist for the student. It helps the students to stay on task, regardless of if they are in the teacher's group or working in cooperative groups.
You could print one for each student or use it to keep track of an entire group's progress. I print it double-sided and collect points until both sides have been filled. I then tally up the points for each student and calculate their participation grade.
