Instructions for Solving Zukei Puzzles
The instructions for the puzzles on Inaba’s website are probably crystal clear if you can read Japanese. Inaba’s original file features 42 puzzles. I used google translate to translate the clues for each puzzle. I made this google doc as a key to allow the puzzles to be used in an English speaking classroom.
Each zukei puzzle provides you with a grid featuring several dots and the name of a shape. The task is to connect some of the provided dots to form the specified shape. The dots must lie on the shape’s vertices.
This puzzle is perfect for practicing geometric vocabulary. These puzzles focus on 8 different shapes:
- Isosceles Triangle
- Isosceles Right Triangle
- Right Triangle
I have used these puzzles with high school students. They are generally familiar with all of these shapes, but they often need a reminder of the meaning of the word isosceles. They also tend to confuse trapezoids and parallelograms.
If you want to use these puzzles with younger grades, it would be easy to use the snipping tool to only select the puzzles that match with the vocabulary you are wanting to practice or your students are familiar with.
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.
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 firstname.lastname@example.org with information about what you teach and where you teach. I will be happy to forward an answer key to you.
