COURSE ACTIVITIES/ASSIGNMENTS:

Homework will be assigned most days. Assignments will be collected and returned the next class meeting. Most HW assignments have a Geometer’s Sketchpad component that must be sent to me electronically. All homework handouts and full solutions will be posted on D2L and on my website (math.kennesaw.edu/~ckoppelm).math.kennesaw.edu/~ckoppelm

Members of the group will be randomly selected to demonstrate the group’s solution in an interview with me and to provide an oral proof that the solution is valid (Details will be provided).

Group Problem-Solving Project: Students will use Geometer’s Sketchpad to form conjectures about the answers to various non-standard geometry problems representing the major areas of study in the course. Students will work cooperatively to present written and computer generated solutions verifying their conjectures.

The Burning House Problem A man is walking in an open field some distance from his house. It’s a beautiful day and he is carrying an empty bucket with him to collect berries. Before long, he turns around and, to his horror, sees that his house in on fire. Without wasting a moment, he runs to a nearby river (which runs in a straight line from east to west) to fill the bucket with water so that he can run to his house to throw water on the fire. Naturally, he wants to do this as quickly as possible.

1.Construct a line segment and label its endpoints A and B. 2.Construct a line perpendicular to segment AB at point A. 3.Construct a point somewhere on the line and label it point P. 4.Construct line segment PB. 5.Construct the midpoint of segment PB and label it point M. 6.Construct segment AM. 7.Display the lengths of AM and PB and make a conjecture about how the lengths are related. 8.Move point P along the line. Is your conjecture still valid? Practice with GSP
