The document provides ideas for celebrating Pi Day on March 14th. Suggested activities include measuring circles to calculate Pi, building a Pi caterpillar, plotting circumferences and diameters to calculate slope, doing Pi trivia, memorizing digits of Pi, assigning musical notes to digits of Pi, and exploring the history and properties of Pi. The goal is to engage students in fun math activities centered around the number Pi.
Bulletin pi day 2021
- 1. Math Bulletin March 2021 March 14 3.14 Dang, it lands on a weekend this year…but you know what it is…Pi Day!! This is the play date where math nerds of the world unite! So this Friday or Monday, why not release your inner math nerd to have some fun with your students, on the third month, 14th day? Here are some ideas: What is Pi?? Even though most students by grade 8 have applied the constant, oddly not many students know what it actually is. Have your kids measure a variety of circles at home or in school—DVD’s, garbage cans, water bottles, clocks, plates, etc. Measure the circumference, then the diameter. (Hint: Sewing tape measures work best for measuring circumference. If those are not available, you can use string, then lay it against a metre stick.) Divide. Take an average of the results. Younger students may be surprised that no matter how big or small the circle, C/D turns out the same…a value just over 3. How close can your class come to the actual value for Pi? Younger students can build a Pi Caterpillar! It can go all around your room or down the hallway. Grade 9 and 10 students: Are you investigating slope? Have your students measure a variety of circumferences (like in #1 above)…and corresponding diameters. Plot the diameters lowest to highest as x value and the corresponding circumferences as y values. Assign a line of best fit, and calculate slope. Voila! Pi! Colorful bar graphs are fun too! It’s also Albert Einstein’s Birthday!
- 2. . How about some Pi trivia? Where did the symbol come from? (Greek letter). Formerly known as..? (The Ludolphian number, after Dutch mathematician Ludoph van Cuelen, who had Pi worked out to 32 decimal places) . First know mention of Pi? (Some sources say Book of Kings in the Bible, approximating pi to 3, others cite ancient Babylonia). First computer to calculate Pi? ENIAC. Here is some fun Pi Day trivia https://www.funtrivia.com/playquiz/quiz602296e7d60.html https://www.braingle.com/trivia/32340/fun-pi-facts.html . Freaky sequences that converge to values with pi Like these: Wait, what??? . Where am I in Pi??? Since Pi is irrational, infinite, transcendental and normal, every conceivable string of numbers is in there somewhere. This site calculates how many digits in to Pi your birthday occurs. I use this for part of a Pi Day contest…people with birthdays showing up earliest in Pi get the points! https://www.facade.com/legacy/amiinpi/ For High School Students: e and Pi go on a blind date https://youtu.be/nKq6_vjrxMo Pi Mnemonics: Here are the first two verses of Mike Kieth’s poem “Near a Raven”. The length of the words corresponds to the first 740 digits of pi! Can your students compose a pi mnemonic? http://www.fun-with- words.com/mnem_numbers.html ENIAC, the first computer to calculate Pi For elementary students—maybe your library has this fun mathy book series?
- 3. The Music of Pi https://youtu.be/OMq9he-5HUU Several groups have done this…assigned a musical note or tone to each digit of pi, and then play it. Well, it’s completely random, and the song goes on….and on… https://youtu.be/HV1-AjwDJwM Pi and Probability (High school—Fnd 30, Precalc 30, Calculus) Explore Buffon’s Needles! https://youtu.be/6jkXBqBOR6o https://youtu.be/szUH1rzwbAw (Gr 7-9) Watch a video from Wolfram math…calculating Pi with inscribed Polygons (Archimedes’ method) https://youtu.be/6- y3Amz9-pE Students can do this! https://nrich.maths.org/841/solution Most fun of all: Who can memorize the most digits of Pi? You’ll be amazed at what your students can do. For a prize, how about a pie?? Or a nice protractor? Here’s the first million digits for your students to get started on! https://www.piday.org/million/ Send your friend a fun nerdy Pi Day card.
