A little more than a year ago now, Sarah Carter shared a set of Japanese puzzles called Zukei Puzzles (see her original post here or access her puzzles here). After having students try out the original package of 42 puzzles, and being really engaged in conversations about terms, definitions and properties of each of these shapes, I wanted to try to find more. Having students ask, “what’s a trapezoid again?” (moving beyond the understanding of the traditional red pattern block to a more robust understanding of a trapezoid) or debate about whether a rectangle is a parallelogram and whether a parallelogram is a rectangle is a great way to experience Geometry. However, after an exhaustive search on the internet resulting in no new puzzles, I decided to create my own samples.

Take a look at the following 3 links for your own copies of Zukie puzzles:

**Advanced** Zukei Puzzles #3

I’d be happy to create more of these, but first I’d like to know what definitions might need more exploring with your students. Any ideas would be greatly appreciated!

##### How to complete a Zukei puzzle:

Each puzzle is made up of several dots. Some of these dots will be used as verticies of the shape named above the puzzle. For example, the image below shows a trapezoid made of 4 of the dots. The remaining dots are inconsequential to the puzzle, essentially they are used as distractors.

If you enjoyed these puzzles, I recommend taking a look at Skyscraper puzzles for you to try as well.

Thanks so much for making more of these. Unfortunately I cannot remember the rules of the puzzle. Is it just to make the required shape connecting any of the dots or must there be a certain number of dots inside/outside the puzzle or ??

I’d love even more – will definitely try these with students!

Thanks in advance for letting me know.

I’ll add some rules. Thanks for the feedback.

Did you know there is an app with similar puzzles? It is called “Pythagorea”. I think you’d like it!

Excited to check out that app! Working on a set of puzzles for elementary kids and thinking about making more with some of the more basic shapes.

I gave my third graders just the puzzles that addressed quadrilaterals and it was eye opening as far as them understanding the attributes…

Embarrassed to ask… is there an answer key? I am stumped on the parallelogram puzzle (2nd row on the right) in extension puzzles #2…

I have not made an answer key (on purpose). I’d rather that we have more people continuing to talk about mathematics than just giving out answers. However…. if you are stuck on this one problem…. you might notice 4 dots in the middle of the page, toward the bottom…. where two of the sides are positioned perpendicular to the bottom of the page. There will be 2 unused dots to the left of this shape… 2 unused dots to the right… and 2 unused dots above it.

Hopefully this helps:)

I love these puzzles! Thank you for making some more 🙂

I also LOVE your skyscraper puzzles. I was teaching a 6th grade elective this spring and used them with the class. After reading your post on it in preparation I decided to make a Slides ppt for them. They wanted to know who you were so I added your Twitter pic to the first slide. Here it is if you’d like to use it too! https://docs.google.com/presentation/d/1rNNqEVUlHARcmpMd2sN2KnNxsV4qeevvAxgAEVgrTX8

These are fun, and great! What I’d *really* like to see (no obligation, of course) are puzzles where the puzzler is to find multiple figures on these dots. For example, “Find a square, two rhombuses, and four isosceles triangles”. That would allow for several correct answers per puzzle, and students would then piece together the fact that there would be four isosceles right triangles for each square…

Could I make your extension and advanced puzzles into a Desmos Activity Builder? I made one for Sarah’s puzzles. https://teacher.desmos.com/activitybuilder/custom/585b4540f24bc103154b8f3a

Go for it. I’d love to see the final product.
