E Brainteaser Puzzle

I recently ran across the E Brainteaser Puzzle. I immediately knew I *had* to create a version of this “E Puzzle” for my classroom. An excerpt of the book Quests and Quandaries: Exploring Intellectual Interests in Depth [link no longer exists] showed up in my google search results. It was through this excerpt that I discovered this delightful brainteaser.

Looking for more alphabet-themed activities and puzzles for your classroom? Here’s a few examples of the other alphabet-related activities I have created.

In the E Brainteaser, students are given paper cut-outs of the letters C, E, and L. They are tasked with using all 3 letters (no overlapping allowed) to create a new letter E.

This can be achieved without flipping any of the pieces over, so this will make a perfect magnetic puzzle to put up on my classroom’s dry erase board.

The author of the book poses this as a way to have students practice the problem-solving strategy of “Change Your Perspective.” Because the book poses the question and immediately shares the solution (I guess it is a teacher’s guide…), I didn’t get a chance to attempt to solve this puzzle on my own.

I did give the puzzle to my husband to tackle to see how he would handle it. He tried many different configurations with little success. I ended up having to give him a hint. Once I did this, he immediately found the answer.

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!

  1. That was fun. I kept thinking, this is impossible, can't be done. Then I read the problem-solving strategy name, and it was easy. Very cool!

    1. I just updated the links to the files for the E Brainteaser Puzzle. So sorry about that! Thanks for letting me know they weren’t working. I really appreciate it!
