11 Prime Days to Celebrate Math Holidays

Math Holidays

If you’re a math teacher, every day is a reason to celebrate math, but did you know that there are also a multitude of “holidays” centered around math? Using a math holiday as an angle to get students excited about math adds up to a whole lot of fun! We hope this list will inspire and energize your math teaching throughout the year.

1. e Day

If you teach any high school students with irrational math fears, then help them transcend their fears on February 7. Euler’s number, e, which is both irrational and transcendental, rounds to 2.7, thus we have e Day on 2/7. Show students the practical use of Euler’s number by introducing them to continuous compounding interest. A little lesson in financial literacy is always valuable!

2. 100th Day of School

The number of creative ways to celebrate this day is certainly not limited to 100! Ask students to bring in containers of 100 small objects and display them around the school. Have students create a list of 100 reasons why they love their school or community. Explore what life was like 100 years ago. Collect 100 food items and donate them to your local food pantry. Visit Help Teaching to use our 100 charts and lessons, as well as all of our number sense worksheets.

3. Pi Day

Pi may be infinite, but Pi Day is not. Celebrate Pi Day on March 14 in recognition of its common abbreviation, 3.14. Plan a party with your students, but wait to sound the party horns until exactly 1:59 in the afternoon (3.14159)! Double the fun and make it a party for Albert Einstein, whose birthday is also on March 14. Be sure to check out Help Teaching’s worksheets featuring the number pi. Pi Day also kicks off World Math Week.

4. Mathematics Awareness Month

Use all 1 + 4 + 9 + 16 days of April to celebrate the beauty and fun of mathematics. Even better, ask your students to create math holidays for any date of the year. For example, April 8, 2016 equals 2^2/2^3/2^4. No matter which date format your country follows, odds are your students can find mathematical significance for any date!

5. Square Root Day

The only thing square about Square Root Day is the date. When the day and the month are both the square root of the last two digits of the year, we have a Square Root Day. April 4, 2016 (4/4/16) is a Square Root Day, but the next one won’t be until May 5, 2025 (5/5/25)! Get radical and make these special days square-themed.

6. Palindrome Days

Palindrome days aren’t just for students named Bob or Hannah. Palindrome days fall on any dates where the numbers of the month, day, and year are the same both forward and backwards. For example, June 10, 2016 is a Palindrome day (6/10/16), but only in countries where dates are written month/day! Challenge your students to formulate lists of future Palindrome dates. Start with five-digit Palindrome dates (M/DD/YY) and work up to eight-digit dates (MM/DD/YYYY).

7. Pythagorean Theorem Day

As proof that the squares don’t have a monopoly on the math holidays, Pythagorean Theorem Day comes around periodically. Also known as Right Triangle Day, recognize Pythagorean Theorem Day whenever the sums of the squares of the month and day equals the square of the last two digits of the year. August 15, 2017 (8/15/17) and December 16, 2020 (12/16/20) are both Pythagorean Theorem Days. Make sure to check out our self-paced lesson on Solving Right Triangles.

8. Math Storytelling Day

No need to divide your instructional time between math and ELA on September 25 (9/25), it’s Math Storytelling Day! Start the day by reading Math Curse, The Grapes of Math, or Sir Cumference or any math story to your students. Try a math story lesson like The General Sherman Tree or Let’s Go to the Zoo. Then, provide a writing prompt and ask students to write and share their own math stories.

9. Powers of Ten Day

Although 10/10/10 has passed, each October 10 can still be used to illustrate the powers of tens. Show your students the power of magnitude by screening the classic film Powers of TenTM. Spend at least one-tenth of your class time this day doing hands-on decimal or base ten exponent activities.

10. Mole Day

No, this day doesn’t pay homage to the subterranean dwellers. Rather, it is a special day for anyone with an interest in math or chemistry. If you remember Avogadro’s number, then you may guess the date of this math day! Mole Day takes place on October 23 each year between 6:02 a.m. and 6:02 p.m. (6.02 x 10^23) during National Chemistry Week. Use Help Teaching’s Chemistry Lessons and this TedEd video to introduce students to mathematical moles.

11. Fibonacci Day

Quick, what number comes next: 0 + 1 + 1 + 2 + 3 + ___? If you said five, then embrace your inner math geek and celebrate Fibonacci Day with your students on November 23 (11/23). Take this day to let your students explore the Fibonacci sequence and the Golden Ratio in nature. Mensa for Kids offers a nice selection of activities perfect for introducing students to the elegance of Fibonacci.
