"Rumors" Teacher Support

_____________________________________________

Rumors Archived PoW || Student Version

Rumors is no longer the current ESCOT Problem of the Week. The student version allows teachers to use the problem with their students without giving the students access to the archived answers. Teachers can use the link to the archived problem to get ideas of student thinking.

Rumors asks students to compare the difference in rates of growth of rumors in a population between a controlled situation and a real-life situation. Given the controlled situation graph, the students are asked to predict how the real-life situation will look in a graph.

This ESCOT PoW could be used to introduce and/or reinforce concepts of linear, step, and exponential functions. Often students don't understand the importance that the constant of time plays in a linear function. This exercise could also be used to compare controlled results vs. real-life results.

If you have something to share with us as you use any of the links or suggestions on this page (something you tried and changed or a new idea), we would love to hear from you. Please email us.
