We are continuing to explore the different ways for kids to see math with 3d printing. Henry Segerman’s new book has been an incredible resource for us in this long-term project:

Yesterday I asked the kids to pick more shapes from his book to print. My older son picked “Topology Joke” and my younger son picked a shape that we’d already printed, but unfortunately the prior pick didn’t survive an unexpected encounter with a book ðŸ™‚ Here are the shapes and what the kids see in those shapes.

“Topology Joke”

My favorite quote – “A torus somehow equals a coffee cup”

Here’s my younger son looking at the trefoil knot on a torus. The interesting thing to me about his discussion of the shape is that he thought the torus was just as interesting as the knot:

At this point we have close to 50 3d printing projects for kids on the blog. Henry Segerman’s work and Laura Taalman’s work have been incredible inspirational for me. I can’t wait to explore more with how 3d printing can help kids see math in a way that was far more difficult to see previously.
