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
I intentionally do not share solutions to the puzzles I feature on my website because I strive to provide learning experiences for my students that are not 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.
