Today is all about pi. I've been scurrying around all morning (while doing "hall duty" for the OGT) trying to make sure I'm ready. It didn't help that I was only here half-day yesterday because I had to take my kid to the doctor. (His finger was swollen about twice the normal size and turning green. I thought I should give in.)

The majority of what I'm doing today was

I'm setting up the following stations:

1. Given 7 different size triangles, use yarn to measure their circumference and diameter. Find the ratio. Then average the ratios. How close are you to pi?

2. Look up your birthday in pi.

3. Read an article about Albert Einstein (it's his birthday today!). Then try to draw a perfect circle. I'm providing a half sheet for them to draw on and a circle printed on a piece of laminate for them to check to see how well they did.

4. Complete a word search using phrases dealing with pi.

5. Read an article about using tau instead of pi and then fill out a unit circle with tau values. (I'm only giving this to my precalc kids.)

6. Eat a pi cookie (

**if**you sing a pi song).

Happy pi day to you too! Thanks for celebrating it - even if you are the only one at your school, you are part of a worldwide community of pi enthusiasts!

ReplyDeleteI'm jealous of teachers who get to celebrate Pi day. It's always spring break in our district.

ReplyDeleteIt sounds like you're going to have a blast!

These are some awesome educational activities! :) Would you be willing to share your pi song booklet?

ReplyDeleteThanks, Meredith, but I really can't take credit for anything except the cookies and the tau day stuff. Check out Jessica's blog for all of the documents.
