This is an activity or homework assignment that can either be done in groups or as an assignment or kids. It has 4 different runners each having a unique scenario where they are running a race. Students will not only need to graph the runners but also solve for speed, and time to complete in order to see which runner will win the race. I have used it for 9th grade and 8th grade physical science as well as an intro to one dimensional motion in physics as well. Kids can either work individually or as a group, I would limit this to a group of two if I were to do it.
