What is e Day?

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.

Puzzle Solutions

I intentionally do not make answers to the printable math puzzles 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 with information about what you teach and where you teach. I will be happy to forward an answer key to you.
