This activity has the students use a LearningCheck document to do the entire activity. The students will explore the procedure to finding the area of a shaded region in coordinate geometry via the steps they will take in their LearningCheck file.
Before the Activity
Students find the area of the circle inscribed in the square in the image.
During the Activity
Students are sent the area_of_triangle.edc file and follow the instructions to determine the area of the triangle on the coordinate plane. An organizer has been created for the students to fill in their work as they proceed. (see chirles_area.doc)
After the Activity
Students practice areas in coordinate geometry using the attached file.
