There are many team activities, and for the CPM Math teachers they are embedded in the daily lessons. Here are 3 of my favorites that can work with any curriculum. All of them tighten up team work, which is one reason they are featured here.
Red Light, Green Light
•The team works together on a problem or set of problems.
•When they finish the problem, then they must Stop.
•The teacher verifies the work/answer with questions.
•The team is then given permission to Go to the next problem or set of problems.
Freyer Model Posters
Freyer modle posters have a specific and easily understood format. I prefer to use them as a summary for a chapter's vocabulary and let them take a whole class period. Eight teams can each take a different term and create a class set of posters to display and teach from in subsequent chapters. A commercial Freyer poster template is available here.
