Double Letters Puzzle – EILQRSU

Taking inspiration from Lisa Richardson, I decided to magnetize the puzzle pieces and place them on my dry erase board instead of laying them on a puzzle table like I have done in the past. Check out previous blog posts here and here.

I’m super excited with the results of magnetizing these puzzles with disc magnets. I’ve had WAY more students attempt them than I ever had last year with the puzzles laying horizontally on the puzzle table. I will definitely be keeping these puzzles vertical going forward!

The goal of each puzzle is to place the double letter cards in a line in an overlapping manner so that a real word is formed. No card may be fully covered, rotated, or flipped.

These puzzles were created by Serhiy Grabarchuk. I found out while doing some googling as I wrote this post that these puzzles are actually known as “DoubLetters” puzzles. Serhiy published another one of his DoubLetters puzzles on in February of 2012. You can download a PDF of that puzzle here.

This double letters puzzle is from Puzzle Box, Volume 2.

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.
