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.
