Homeschool Pi Day Activities

Yes, you guessed it. I am a math geek! I love math. And any reason to celebrate math is good to me. So this Saturday happens to be 3.14.15 or Pi Day!

Do you remember this from school? Pi is the ratio of the circumference of the circle to the diameter of the circle. And the cool thing is that this ratio  is the same for all circles.

Pi is an irrational number which means it cannot be written as a fraction and that when written as a decimal it will just go on and on and on and on... without repeating. The actual digits are 3.14159265359...

So what can you do to celebrate this beautiful holiday of mathematical deliciousness?

1. You could have your kids find circular objects, measure the circumference and measure the diameter. Then divide. After a few objects they should notice that all of their answers are near 3.14. And you can discuss how human error might get in the way of getting exactly the same answer.

2. Make a Pi chain with colored pieces of construction paper. Assign a color to each digit (i.e. 0 - red, 1 - green, 2 - blue, etc.) Then use the chain to practice memorizing the digits of pi. On Sunday you could have a competition to see who has memorized the most digits.
(You could also do this as a bracelet with pipe cleaners and beads. Math bling!)

3. Like music? There are several pi songs out there. Check out some here, here, here, and here. Or make up your own music!

4. Check out the history of pi or some funky stuff about pi at Joy of Pi.

5. Make a pi day piece of art or t-shirt that shows off what you know.

6. Find out how pi is used in other types of math (calculus, trigonometry, or even other geometry applications.

7. Make a pie or cake  and decorate it with pi info that you learned. Then, of course, eat it!
