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 diameter of the circle). Calculate the circumference of the circle by taking pi times diameter. C = πd
- 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
