I love it for several reasons:
1. It is private- kids can only join when given a unique join code by their teacher.
2. Once the students join, you lock the group and the code is no longer valid.
3. Parents can see their own child's progress by the join code on the side bar of their child' account. Parents can only view their own child's information, grades and messages and assignments you post to their child or directly to the parent.
4. SMALL GROUPS! An excellent way to create differentiated assignments in your classroom.
See my presentation below for general information and samples of small group assignments.
