Trying to study knots with 5 crossings

We’ve been doing a little bit of work with knots lately. Today we were studying the knot with 5 crossings, and it wasn’t so easy. I’d guess ahead of time that 5 crossing would be tricky. There’s a lot to keep track of! Even what seems like a simple task – making a knot with … Continue reading Trying to study knots with 5 crossings

Exploring the knots with 4 and 5 crossings with kids

In our last project we explored the trefoil knot: That project is here: An introductory knot activity for kids Today we moved on to the knots with 4 and 5 crossings. We started off by comparing the trefoil knot with the 4 crossing knot – what is the same? what is different? Also – the … Continue reading Exploring the knots with 4 and 5 crossings with kids

Playing with 3d printed knots from Mathematica

Yesterday I learned that Mathematica has a wide variety of knots that you can 3d print. We’ve done a few knot projects in the past. Here are 3 of them: Playing with some 3d printed knots Dave Richeson’s knotted bubbles project Exploring Colin Adams’s “Why Knot?” I thought that actually being able to hold the … Continue reading Playing with 3d printed knots from Mathematica

Playing with some 3d printed knots

Today we looked at some 3d printed knots designed by Laura Taalman and Henry Segerman. Two are versions of Taalman’s “rocking knot” which we found here: Laura Taalman’s Makerhome blog: Day 110 – the Rocking Knot The second is the Torus knot from Segerman’s new book Visualizing Mathematics with 3D Printing. We started the project … Continue reading Playing with some 3d printed knots

3d printing ideas to explore math with kids

Over the winter break I began to think about collecting some of our 3d printing projects into to one post to highlight various different ways that 3d printing can be used to help kids explore math. The post got a little long, but if you are interesting in thinking about 3d printing and math, hopefully … Continue reading 3d printing ideas to explore math with kids

Sharing Sam Hansen’s “Knotty Helix” podcast with kids

The latest Relatively Prime podcast is fantastic: The short description from the podcast’s website is: “Sure DNA is important, some might even claim it is absolutely integral to life itself, but does it contain any interesting math? Samuel is joined by UC-Davis Professor of Mathematics, Microbiology, and Molecular Genetics Mariel Vazquez for a discussion proves … Continue reading Sharing Sam Hansen’s “Knotty Helix” podcast with kids

*Ten 3D Printing math projects to help students explore math

Yesterday I was able to watch the Global Math Project presentations (well, most of them) via the Facebook Live feed. Hopefully those videos will be preserved here: The Global Math Project’s Facebook page One tank that caught my eye was given by Henry Segerman. I’d guess that his work and Laura Taalman’s work account for … Continue reading *Ten 3D Printing math projects to help students explore math

An intro knot activity for kids

I’ve been doing a lot of thinking and playing with our various 3d printed knots lately. It feels like there are lots of great projects for kids here, but I’m struggling a little to find them. Last night I tried something pretty simple – take several different versions of the trefoil knot and have the … Continue reading An intro knot activity for kids

Dave Richeson’s Knotted bubbles project

Saw this tweet from Dave Richeson last week which basically “had me at hello”: here’s the video in cast the twitter link doesn’t work: We’ve done a few bubble projects in the past, so the boys were already familiar with the basic concept: Zometool and Minimal Surfaces Trying out 4 dimensional bubbles More Zome Bubbles … Continue reading Dave Richeson’s Knotted bubbles project

Exploring Colin Adams’s “Why Knot?”

I bought a copy of “Why Knot?” last spring and we played with it once: Playing with Colin Adams’s “Why Knot” I brought it out again today to explore a bit more about knots with the boys. The goal of the project today wasn’t depth, but rather just exposure to some basic ideas in knot … Continue reading Exploring Colin Adams’s “Why Knot?”
