###### Circles are EVERYWHERE, and wherever there are circles, there’s PI!

**How can I spend my Math Minutes this week?**

- Explore the wonders of Pi on @Wonderopolis: http://wonderopolis.org/wonder/what-is-pi/ Post something new you learned in the comments below. Make sure when leaving a comment you only put your first name, your grade, and school (i.e. Trevor, 4, Sunset).
- Find circles in your environment and snap some pictures. Make a Pic Collage (or use another app of your choice) and send it to the EY coordinator at your building. Take it a step further and snap the picture with a ruler going though the center (measuring the
of the circle). Calculate the*diameter*of the circle by taking pi times diameter. C = πd**c****ircumference** - See how close you can get to pi by following the steps below:

**Step 1: **Measure the diameter of a circle. I used the top of my QT cup in the picture below. I measured the diameter as 11.5 cm.

**Step 2:** Measure the outside of the circle (circumference) with a string (I used a piece of making tape folded in half because I didn’t have a string handy).

**Step 3:** Measure the string. I measured the circumference of my QT lid as 36.5 cm.

**Step 4: **Divide the circumference by the diameter (36.5 divided by 11.5). I got 3.17391304. Not too bad!

**Send your pi calculations to the EY coordinator at your building.**

My pi day is on the digit 67,195 of pi. My piday is the fourth in my group.

What I learned in Wonderopolis is that 22/7 is the closest simple fraction to pi

I learned on Wonderopolis that pi’s symbol is a Greek letter.

I learned that pi never ends it keeps on going

I learned 72 digits of Pi

My Pi day is 2,805
