### Did you know various math topics have special days solely dedicated to it? Learn about some of these holidays in this math mini spark.

### Spark your math thinking!

1. Set up your math mini spark recording page: #10: Celebrate Math!

2. What is **Pythagorean Theorem Day**? To qualify as a Pythagorean Theorem Day, the digits that make up the date must qualify as a pythagorean triple. The next pythagorean triple date will be on July 24, 2025 since 7^{2} + 24^{2} = 25^{2}. Do some research and find some other dates that were or will be Pythagorean Theorem Days.

3. **Mole Day** is celebrated on October 23. Read about mole day and take notes about this day on your recording page. Make sure to define a mole in your notes.

4. The Fibonacci sequence begins like this: 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144…. November 23 is celebrated as** Fibonacci Day** because when the date is written in the mm/dd format (11/23), the digits in the date form a Fibonacci sequence: 1,1,2, 3. Watch this video about this special number pattern. Add notes to your recording page.

**5.** **Pi Day** is on March 14. Watch this short video about this day. Add some interesting details from the video to your recording page. Then, go to this site to find out how long until we celebrate pi day again (to the nearest second). Record this on your recording page.

6. Share your math mini spark recording page with your teacher/EY coordinator.

I learned that fibonacci numbers go to the negatives. I didn’t even think about it before!

I learned that in the fibonacci sequence is the series of numbers where a number is the sum of 2 numbers before it. Also I learned that November 23 2058 will be the biggest fibonacci day ever because 2+3 is 5 and 3+5 is 8
