Tom,
I use something like the form attached. To keep it simple, I use a 100 point scale, then do a light curve on the totals, to convert the totals to a letter or number grade, which value then plugs into the overall grading scheme.
Each student gets a copy of the form, which includes his/her team members.

Subject: Peer Evaluation Form

I am almost through my first semester with TBL and it has been one hell of a lot of work; I am hoping next semester will be easier now I have things set up. However, I am stuck on the peer evaluation forms. I just don't get it. If I have a seven-member team and the team evaluation score is worth 10% of the overall course grade I would ask them to distribute 60 points across the members. But then what do I do?

In DRAFT1 attached are the names in a seven-member team. I would ask them to distribute 60 points. Okay, they do this as in DRAFT2, but now what do I do. Sally has 90 points - does this mean she only gets 9 out of 10 for the team evaluation component? Does this mean no one can 10 out of 10? Something is wrong here.
