I would recommend you have a glue gun available for each team, as that is what they all seem to want to use - I use the low temp mini glue guns. I guess you could limit the ones available and force them to go in other directions... I would also recommend having an abundance of Popsicle sticks on hand as that seems to be a favored building material.
We also discuss a few other fees and fines..
The teacher's role in this process is to act as a consultant. If you have a question that the group cannot answer, you may pay the consultant $200 for each question. Be sure to phrase the question carefully so that the response is not too simple (yes or no).
Any item purchased must be incorporated in the model. There is a penalty fee of $500 for each missing item.
Any group that does not clean up before class is over will be penalized $1000 for each safety violation.
Armed with all this information as well as a team folder (containing plain white paper, graph paper, accounting ledgers, "checks" and shopping sheets) I send the teams off to begin planning.
The following day students can begin construction. Since I taught a few grade levels, I had a cart loaded with all of the supplies available for purchase that I would roll out for the appropriate class periods.
Next Tuesday we'll talk about testing the buildings, a group write-up/paper and tie up any other loose ends. I will also try to make my documents available for you to download.
