| Part 5: Checking More Homework and Introducing a New Formula [Begin: 32:40]
|
After the students finish the worksheet, the teacher asks them to get out "The worksheet we did on Friday after the quiz." This worksheet has two problems. The first contains a map of two streets intersecting in a 45 degree angle with a triangular shaped piece of land between the streets. A boundary line divides the piece into two parking lots. The task includes finding the measure of the angle formed by the property line and First Street, and suggesting a more equal way to divide the lots. The teacher elicits the answers to these questions from the students, helping out when the students are stuck. The second problem involves finding the sum of the interior angles for a six-sided figure. The teacher asks students for the answers they found using their protractors. The teacher then presents a formula and asks students to try it out. | ||
