Cooperative Learning Groups & Responsibilities
Engage/Activate!
Cooperative Learning Groups & Responsibilities
1. Sort the entire collection into three
groups so that no triangle belongs to
two groups.
2. Give a description or name to each of
the groups and record on chart paper.
3. Once you have found one criterion for
