Domino Effect Puzzle

When I shared a photo of the Domino Effect Puzzle (this week’s magnetic puzzle of the week) on twitter, someone was quick to point out that I need to share the file on my blog.

This week’s puzzle is from Brainteasers: 195 Puzzles to Keep You Sharp!

Students are given 8 dominoes. The goal of the puzzle is to arrange these 8 dominoes to form a 4 x 4 square in which the number of pips in each row and each column is the same.

I put magnets on the back of my dominoes and posted the puzzle on the dry erase board.

But, I also made a tabletop version with smaller dominoes and a template to set them on top of.

I had a handful of students give this puzzle a try this week, but there was much less participation than usual. I’m not sure why…

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.

This one was easy once I did the math equation. Total number of pips, divided by 4 = total pips per line, vertically and horizontally. I even got one diagonal to add up also but not both diagonals.

I love hearing how people approach solving different puzzles!

Can the number of pips in each column be different than the number of pips in each row? Also, do all the dominoes have to be horizontal or can they be both horizontal and vertical? Thanks - as I am trying to work this one out myself before presenting it to my class.

Do you think all your students know that "pips" = "dots"?
