This morning between classes I outlined a first worksheet for a series of math topics that I want to add to my physics classes before the end of the semester. I think the first one is particularly clever and succint, so I'm publishing it to show it off. It's called Error in Measurement.

UPDATE: after Googling around for a while, I actually found a lot of related material on the web. I'll be expanding this into a week-long lesson at the beginning of next year, I think.
