Since there are four groups of five, two groups of four will be on opposing positions. For example, the groups will be labeled A, B, C, D. A and B will be for and will be debating with C and D by e-mailing each group. Each member of every group will have a responsibility. One will be the recorder, facilitator, typist, moderator, and speaker. The responsibilities will be rotated at every group gathering.
Typist job is to report any new information to the group.
Then the group discusses an appropriate response to the other group. Read all the other groups statements. Discuss with your group ways to help the other groups to improve their statements in grammar, information, or proper vocabulary. Once it has been discussed with the group the typist needs to responds to the other groups. Discuss with the whole class their position.
