Fibonacci Day Activities and Resources
Celebrate Fibonacci Day on November 23rd with these fun activities, puzzles, and resources!
What is Fibonacci Day?
Fibonacci Day is celebrated each year on November 23rd (11/23) because the digits in the date—1, 1, 2, 3—represent the beginning of the famous Fibonacci sequence. In this sequence, each number is the sum of the two numbers before it: 1, 1, 2, 3, 5, 8, 13, and so on.
The Fibonacci sequence appears throughout nature, from the arrangement of petals on flowers to the spirals of pinecones and seashells. Fibonacci Day is the perfect opportunity to explore patterns, sequences, and the surprising connections between math and the natural world.
Celebrating Fibonacci Day can help show students how math can be found everywhere around us!

Donna Lasher shares the idea of a Fibonacci poem, or a “fib poem.” This is a six-line poem in which the syllables in each line of the poem reflect the sequence.
- Line 1: 1 syllable
- Line 2: 1 syllable
- Line 3: 2 syllables
- Line 4: 3 syllables
- Line 5: 5 syllables
- Line 6: 8 syllables
- and so forth…
Puzzle Solutions
Puzzle solutions are available on a password-protected solution page. I do not openly post the puzzle answer keys because one of my goals as a resource creator is to craft learning experiences for students that are non-google-able. I want teachers to be able to use these puzzles in their classrooms without the solutions being found easily on the Internet.
Please email me at sarah@mathequalslove.net for the password to the answer key database featuring all of my printable puzzles and math worksheets. I frequently have students emailing me for the answer key, so please specify in your email what school you teach at and what subjects you teach. If you do not provide these details, I will not be able to send you the password.
Not a teacher? Go ahead and send me an email as well. Just let me know what you are using the puzzles for. I am continually in awe of how many people are using these puzzles with scouting groups, with senior adults battling dementia, or as fun activities in their workplace. Just give me enough details so I know you are not a student looking for answers to the puzzle that was assigned as their homework!
