Happy Pi Day!

Thursday, March 14th is Pi Day!   How are you celebrating this fun math concepts with your students?   In our yearly circle around the sun, Pi Day comes but once a year. Pi Day is March 14, or 3.14, to celebrate the first three digits of everyone’s favorite irrational number.

Here are some fun ideas that were shared with me from a friend from the website, "Flocabulary - hip hop in the classroom".

Celebrate Pi Day with these activities:

1. Check out the video below.  One person made a massive domino spiral celebrating pi. Have your students use pi to estimate how many dominos are in the spiral. (10,059, according to the creator - they show the math problem at the end of the video).

2. Bake a pie or pizza pie. Use pi and circle formulas to determine its circumference, area and volume. When you cut it up to serve, determine the area of each slice. Eat and enjoy.

3. Review the long history of the discovery of pi.

4. Use our Writing Academic Rhymes lessons and have your students write a mnemonic rap to memorize at least 20 digits of pi.

5. Log onto Google Maps and have students scour maps of your hometown for circles (tops of water towers, roundabouts, swimming pools). Using the key, have students calculate the circumferences and areas of the circles.

6.  BrainPOP has a great video on Pi.  Complete with activities and a quiz!   Click here for the Pi video!  You may need our log in information.  Click here if you need it!
