My son and I watched mathematician Dr. Katie Steckles cut a square with just one cut. This is an idea that dates back to 1721 in Japan: The Fold and Cut Theorem. My son was fascinated by the one cut idea so we decided to try it out ourselves.
We started with the 1 cut square.
Fold paper in half.
Crease the paper you just folded in half.
Fold into a triangle shape.
Cut a straight cut from the corner.
Ta da! One cut square!
After watching her video, we decided to figure out the Betsy Ross star. It took my son three attempts to get it down so here it is in hyperlapse vide0.
I saw this Star Wars cut art on Childhoodist Instagram. My son loved it so this is our final cut paper STEM art project. These Star Wars cut paper snowflake designs are from Anthony Herrera Designs.
They are not so easy to do and require a cutting board and an Xacto knife. He gave up on it saying that it was too hard but it might be fun for someone older.

Wow–that is very cool, Mia! Will have to try it out!
My son likes these kind of STEM puzzles and he really enjoyed it. I can’t believe there is theorum behind it though that makes sense.
Those are some intricate snowflakes. What an art! I used to love making them as a child.
My son gave up on the Star Wars snowflakes. They are pretty hard to cut out even if you use an Xacto knife and cutting pad. They look so amazing though!
What a great STEM activity!
It was really fun to cut the perfect star shape with just one cut!
Great bonding moment with your kids.
Thanks so much Jane! It was a fun project and, more importantly, quick, easy and uses stuff you already have around the house!!! (which is what I need!)
This is amazing! Like magic. And I love, love that all you need is a piece of paper and some scissors.
I like those kind of projects best; I need the stuff required to be lying around the house or it is a determent for me.
Just tried out the origami paper folding star and loved it! Generally we like trying out crafts with simple requirements and get our ideas from Activity Village or Jumpstart Crafts. Through this post, we also found the fold and cut you tube video, which is fantastic!
Thanks for the wonderful posts!
It’s like magic, isn’t it? We were delighted with it as well! My son likes these kind of mathy-art projects.
