The
Mathematics Court Case Task
Goal: The goal is to settle a dispute over the relationship between area and perimeter.
Role: You are a geometry expert called to testify in a court case.
Audience: The audience is the judge and jury who are not necessarily mathematically oriented.
Situation: Lou and Sue were recently discussing whose garden had the most area to plant flowers. Lou claimed that rather than compute the area of the gardens, they could simply walk around the two gardens to get the perimeter and the one with the greatest perimeter would have the greatest area. Sue told Lou that he was crazy because greater perimeter does not automatically mean greater area. Lou and Sue broke into a fight and now are in The Mathematics Court trying to determine who is correct.
Product: You are to write the speech that you will deliver on the witness stand that enables the judge and jury to decide whether Lou or Sue is right. In addition to the speech, you will prepare an 11 inch by 14 inch poster that contains examples which support your argument. Within your speech, you should refer to the examples contained on the poster.
Standards: You may assume that both Lou and Sue understand the concepts of area and perimeter and they are not simply getting these terms confused. However, a brief discussion of these terms is appropriate to begin your speech for the sake of the judge and jury. Your task should be typed and should include a copy of the attached rubric.
