Explore the effect of other assumptions and parameters. Ask the students to summarize their major learnings, and to think of similar situations where their learnings apply. The intergroup goal is for triads to check each other's work and provide any suggestions and assistance other triads need to obtain a better answer. Partners check each other's work. Another triad checks each triad's work.
Teacher randomly selects individual members of the groups to present.
Each member of group can explain answer and method. Whenever it is helpful, check procedures, answers, and strategies with other groups. Monitor to catch misunderstanding in the early stages and to help establish the rules. Remind groups that all are expected to participate, and understand and be able to explain their formulation and solution. Ask groups to discuss effectiveness by individually listing two things that went well and one thing the group needs to work on.
