This fraction dominoes puzzle asks students to arrange an entire set of dominoes (except for the 0:0 tile) to form six correct addition equations involving fractions. Each domino tile should be considered as a fraction.
This puzzle is the creation of L.P. Mochalov. I originally found the puzzle in Mochalov’s Totally Tough Brainteasers book, but it is also available for free on his website.
This is the second domino puzzle from this puzzle creator that I have typed up to use in my math classroom. Previously, I shared Mochalov’s Domino Pyramid Puzzle which involves perfect squares.
I created a template for this fraction dominoes puzzle that is designed to print on 11 x 17 cardstock. It is perfectly sized to use with the small sets of dominoes available from Dollar Tree for $1.25.
Dollar Tree’s dominoes (shown below on the right) are slightly smaller than a standard-sized domino, but you definitely can’t beat the price!
I wanted to also make a template to use with standard sized dominoes, but I am having trouble figuring out how to make that fit on a standard sized sheet of paper. If anyone has any ideas, I am open to hearing them!
The students must treat each domino as a fraction. For example, I could use the 1:2 tile and the 3:2 tile to make the equation 1/2 + 3/2 = 2.

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!
