Description

I love math puzzles, and with the help of Ken Irvine of NJ, we came up with the Math Snake idea. The idea is to rotate them until there is a correct equation on all 4 sides of the blocks. The equation is read from left to right, irregardless of operation priority.

There is a 7 block model (here) and also a more difficult 9 block model offered on a different listing. They are high quality all wood construction with deeply burned laser engraved numbers from our shop in Hudson, FL. The blocks stay as a string but will rotate individually. The 7 block model may look easy, but it's not really as there are 1024 possible permutations of the blocks, but only ONE correct solution. (Note on the 9 block version there are 16,384 permutations but only 1 correct solution.)

Ken Irvine wrote the program to develop the math layout on the blocks. As it turns out there are a number of possible ways to burn the numbers on the blocks and still have a unique solution. So there are 20+ different models we can offer on each of the 7 block or 9 block models. If you are a school teacher or puzzle enthusiast who wants more than 1 snake with each one being different I can do that for you! Just let me know how many different ones you want.

Fun! Great gift for kids and adults!

My 9 year old son loves this! He's on the spectrum and doesn't care for a lot of lights and sounds from 'typical' fidgeting toys, he looooves this.

Definitely 100% recommend!

This will be a good practice tool for our second grade grandson who loves math.

Gift to severely handicapped ex math professor. His caretaker helped me choose this,and now I hear he plays with it a lot.

So excited for my math loving son for his stocking! Great quality.

Math Snake 7 Wood Brain Teaser | Math Puzzle for Kids

Very fast shipping & recipient is still working on it! Very happy.

Good quality and great challenge, thanks!

Very well made! I have purchased from this seller multiple times and I’ve never been let down. All of the products are great quality! Thank you!

Good for an adult math lover! He figured it out faster than I thought he would, but not as fast as he thought he would.

The Math Snake is a clever concept for a math manipulative. I bought it for my elementary-aged grandchild. The parents seemed to play with it more! The item came well-packaged and on time.

Bought as a gift to our resident math expert. He loves it!

Shipped quickly and was a great gift!

The 7 block math snake is awesome. Very difficult. Got it for a 7 years old nephew and my brother took it instead!

Fast shipping and well made. Thank you!

great service

My mom teaches math, so I got this for use in her classroom. Her students love it. It's highly durable, so not even a bunch of grasping pre-teens have been able to break it. It came nice and fast, as well, so they could enjoy it before Christmas break. Thanks!

Frequently Asked Questions

What is the Math Snake 7?

It is a wooden math brain teaser built as a string of seven connected blocks. The blocks stay linked but each one spins on the string, and your job is to turn them until all four long sides of the snake read as a correct equation. It was developed in our Hudson, Florida workshop with New Jersey puzzle designer Ken Irvine.

How do you solve it?

Rotate the seven blocks until every one of the four sides forms a valid equation read straight across. The catch that trips people up is that each equation is read left to right exactly as written, ignoring the usual order of operations, so 2 + 3 x 4 is worked in sequence rather than doing the multiplication first. All four sides have to come out right at the same time.

It looks easy. Is it really?

It looks simple but it is not. There are 1,024 different ways the seven blocks can be turned and arranged, and only one of them solves all four sides at once. Ken Irvine wrote the program that worked out the number layout to guarantee that single unique solution.

Who is Ken Irvine, and who created it?

The Math Snake was developed in our Hudson, Florida workshop together with Ken Irvine, a New Jersey puzzle designer who wrote the program that lays out the numbers. Irvine has created more than 50 puzzle designs since his first, "The Nagging Wife," and his puzzle Trifecta won a top-10 award at the 2015 Nob Yoshigahara Puzzle Design Competition.

Is there a harder version?

Yes. We also make a 9-block model, the Math Snake 9, on a separate listing. It has 16,384 possible arrangements with, again, only one correct solution.

Is it good for classrooms, and can I order in bulk?

Yes, this is one of our most popular pieces with teachers, homeschoolers, and math clubs. There are more than 20 different number layouts for the 7-block model, each with its own unique solution, so a whole class can work at once on snakes that look and solve differently, with no two students sharing the same answer. We make every snake to order, so tell us how many different ones you need for your classroom, co-op, or group and we will produce a matching set.

What is it made of, and how is it made?

It is solid wood throughout, with the numbers burned deep into each face by laser engraving so they will not wear off with classroom handling. Each snake is cut, engraved, and finished by hand in our Hudson, Florida workshop.

Who is it for?

It is built for kids, math lovers, homeschoolers, classroom teachers, and Montessori-style learning. The left-to-right equation rule turns order-of-operations practice into a hands-on game, which is why teachers reach for it as a math center activity and a STEM gift.

Can I personalize the Math Snake 7?

Yes. The Math Snake 7 can be personalized with a custom laser engraving. Add a name, date, or short message when you order. See our laser engraving page for details and examples. For a custom logo or artwork, request a quote for custom work.
