Slope of a Line Activity
This in-class activity provides a quick check for the instructor as to a student's understanding of slope.
To begin:
A quick assessment of student understanding can be performed by the instructor walking around the classroom and observing the steepness and directionality of the spaghetti or chenille stem. Alternatively, the instructor may remain at the front of the room and complete a scan of the classroom. The following Slope of A Line Activity Key may be used to assist the instructor with this method, since the instructor perspective will be upside down from the student view.
Extensions of this activity may include a more sophisticated coordinate system where instructors can ask students to graph lines with a specific slope and y-intercept or graph equations that are parallel or perpendicular.
