Product Description
Use circles to find Diameter and Circumference and Solve for C/D
Students draw their own circles, find and measure the diameter and circumference in inches and centimeters, and discover that C/d yields pi!

Great for Pi Day or ANY day when you want your students to understand Pi!

This worksheet also includes Question and Answer QR codes. The question is one posed to NASA's Jet Propulsion Laboratory: How many digits of pi do you use in your equations? The answer is a link to the website containing the answer by one of NASA's engineers. (15 digits after the decimal)

The teacher page also contains historical information regarding pi as well as a link to a pi day poster that poses a question related to pi.

You include a tub of supplies including various sized circles, string, rulers, scissors and colored pencils (for fun). Students get to pick their own 3 circles to draw, measure, and label. Finally they solve for pi. There is no mention of pi or specifically how to measure the circles. There are lots of ways but it's great for students to figure it out for themselves!

What’s included:

- One page Discovery Sheet
- One page Discovery Sheet example answers
- Teacher page that includes materials needed and possible discussion topics.

Students get to move around and learn for themselves!
