A Math Problem
One of my mentors, Michael Kaechele, asked me if I could come up with some sort of problem for his math class. His math class is currently taking a unit on perimeter, area, and volume. I wanted to do something a bit more than just a little word problem . I decided to use a video and create a real-life problem, similar to what Dan Meyer does (although nowhere near as good).
I used the University of Regina’s Academic Green as my example and asked how far of a walk it would be to walk around the perimeter of it (assuming it is a perfect circle). I measured in steps, mostly because I didn’t have anything capable of measuring a large distance and partly because I felt it brings a real life aspect to the problem. I then took it further to incorporate an area problem and asked how big of an ice rink could I fit into the green if I wanted to do so. To close off the video, I ask what is wrong with how I measured for problem, hoping to spark some thoughts that maybe steps isn’t the best or most consistent way to measure. I also hope they discuss the fact that the green isn’t a perfect circle, and how that could change the problems.
Anyways, this is my final product:
Let me know what you think and if you have any suggestions for any future videos!
