Finding the volume of a rhombic dodecahedron with our zometool set

Yesterday we did a neat project inspired by a tweet from Alex Kontorovich: Sharing a 3d geometry idea from Alex Kontorovich with kids via zometool At the end of that project a question about finding the volume of a rhombic dodecahedron came up. Since I was going to be out this morning (and my older … Continue reading Finding the volume of a rhombic dodecahedron with our zometool set

Calculating the volume of our rhombic dodecahedron

Yesterday we did a fun project involving a rhombic dodecahedron: A project for kids inspired by Nassim Taleb and Alexander Bogomolny At the end of that project we were looking carefully at how you would find the volume of a rhombic dodecahedron in general. Today I wanted to move from the general case to the … Continue reading Calculating the volume of our rhombic dodecahedron

Revisiting the Rhombic Dodecahedron

Yesterday we looked at the 24-Cell, or “hyper-diamond” inspired by Matt Parker’s latest video: Using Matt Parker’s Platonic Solid video with kids Today I wanted to take a step back and look more carefully at the rhombic dodecahedron. It is a shape we’d studied a few times before: A 3D Geometry proof with few words … Continue reading Revisiting the Rhombic Dodecahedron

Sharing a 3d geometry idea from Alex Kontorovich with kids via Zometool

I saw an interesting tweet from Alex Kontorovich earlier this week: We’ve looked at but the Cuboctahedron and the Rhombic dodecahedron before, but I thought it would be fun to revisit the shapes. I also hoped that we’d be able to recreate the shape in the picture with our Zometool set. So, first we built … Continue reading Sharing a 3d geometry idea from Alex Kontorovich with kids via Zometool

Extending our Alexander Bogomolny / Nassim Taleb project from 3 to 4 dimensions

Last week I saw really neat tweet from Alexander Bogomolny: The discussion about that problem on Twitter led to a really fun project with the boys: A project for kids inspired by Nassim Taleb and Alexander Bogomolny That project reminded the boys about a project we did at the beginning of the summer that was … Continue reading Extending our Alexander Bogomolny / Nassim Taleb project from 3 to 4 dimensions

A project for kids inspired by Nassim Taleb and Alexander Bogomolny

I woke up yesterday morning to see this problem posted on twitter by Alexander Bogomolny: About a two months ago we did a fun project inspired by a different problem Bogomolny posted: Working through an Alexander Bogomolny probability problem with kids It seemed as though this one could be just as fun. I started by … Continue reading A project for kids inspired by Nassim Taleb and Alexander Bogomolny
