e Day Nonogram Puzzle
Bring some puzzling fun to e Day (February 7th) with this free printable nonogram puzzle.
The mathematical constant e is known as Euler’s Number. Since the decimal approximation of e is 2.71828…, mathematicians celebrate e Day on February 7th.
This mathematical holiday is often only celebrated in upper-level math classes at the high school level since students are usually introduced to the constant e for the first time in Algebra 2 or Precalculus courses.

What are Nonogram Puzzles?
Nonogram puzzles, also known as Picross or Griddlers, are logic-based grid puzzles where players use numeric clues along rows and columns to fill in or leave blank squares, revealing a hidden pixel art image. The numbers indicate consecutive groups of filled squares, separated by at least one blank square.
If you aren’t familiar with the process of solving a nonogram puzzle, this free PDF demo book from Griddlers.net has a great visual of the rules for solving that I often use with students.

Puzzle Solutions
I intentionally do not make answers to the printable puzzles and math activities I share on my blog available online because I strive to provide learning experiences for my students that are non-google-able. I would like other teachers to be able to use these puzzles in their classrooms as well without the solutions being easily found on the Internet.
However, I do recognize that us teachers are busy people and sometimes need to quickly reference an answer key to see if a student has solved a puzzle correctly or to see if they have interpreted the instructions properly.
If you are a teacher who is using these puzzles in your classroom, please send me an email at sarah@mathequalslove.net with information about what you teach and where you teach. I will be happy to forward an answer key to you.
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, as fun activities in their workplace, or as a birthday party escape room.
