My husband was looking for a lesson idea to use with his geometry students after they finished with their semester tests. I suggested he give them some sort of logic puzzle to work on, and I reminded him that I had blogged about a bunch of them before! After looking through my blog posts, he decided the Zukei puzzle fit exactly what he was looking for! You can read my original post about Zukei puzzles here.
Here are the instructions for the Zukei puzzles on Inaba's website:

The puzzle file from Inaba features 42 puzzles focusing on the following geometric vocabulary words: square, rectangle, isosceles triangle, isosceles right triangle, right triangle, rhombus, trapezoid, and parallelogram. This summer, I used google translate to translate the clues for each of the 42 puzzles. I made this google doc as a key to allow the puzzles to be used in an English speaking classroom.
To make the puzzles easier to use in our classrooms, I used the snipping tool and the google doc to make an English version of the activity. My version ended up being six pages long. Then, I sent the file to my husband. He rearranged the images and labels to compress it into a four page document.
We both ended up using his compressed version with our classes right before Christmas break. My trig students weren't the happiest about having to do work on the LAST day before Christmas break, but they survived. It definitely stretched their brains. For my trig kids, it had been a couple of years since they had been required to think about shapes like parallelograms and rhombuses. So, it was a nice vocab review for them.
I also gave a set of puzzles to one of my 8th graders who is taking Algebra. This student LOVES challenges and puzzles! When he was struggling with the parallelograms, we started talking about how we can take what we had learned about parallel lines having the same slope in Algebra 1 and apply it to these puzzles.
These puzzles are fun. And, they are frustrating! We won't talk about how long I was stuck trying to figure out puzzle number 6! In fact, I only figured it out because a student spoiled it for me!
I feel like I need to remind you once again that I did not create these puzzles. I simply re-formatted them to make them usable in English speaking classrooms. All of the puzzles were created by Naoki Inaba. Here is his full page of math puzzles.
Here is what the four page file of puzzles looks like after being translated by me and arranged by my husband.
The files (both the six page and four page versions) have been uploaded here in PUB and PDF format.
Ever since I used them in class, I've been thinking about how to modify them for use in my Algebra 1 class. I would love to have these puzzles on a coordinate grid. Then, students would have to write the equations of the lines that went through each pair of points to form each shape. Hmm...
