Since the principal special requested math-art to decorate the 9th floor hallway I finally get to do a project with my students. Unfortunately, I’m pressed for time and I have to do a one day in-class project with posters up by Friday. But fear not students, I think I have an idea.
I found this online and it’s pretty much what my co-op described he wanted to do. In 48 minutes I think we can move this 2 day 7th grade lesson to an 11th grade discovery activity. Furthermore I know these students do not know what pi really means – hell it took me a whole week to teach that it was irrational (but they ALL got that one right on the previous quiz, yay!).
The one thing I preferred about the original activity was that students measured 6 different objects on their own. My students really struggle with measurement in general (i.e. they don’t quite know 12 inches in a foot etc.) so I don’t want to take away from the purpose of the project by creating too many obstacles but I also don’t want to lose the fun in it.
The students will measure 2 pre-cut different sized circles and fill out the worksheet accordingly. I was thinking to put a big grid on the board where all the students would record their final column. Once we discover that “Hey – that’s pi!” – we’ll see which student measured closest to pi which can lead us to discuss measurement error and so forth.
Thoughts? Revision suggestions? This is not happening until Wednesday so I look forward to your comments.
