# Further fun with the Archimedean Solids at the Curious Minds Club (St Thomas of Canterbury Primary School, 13 March 2020)

This week at the Curious Minds Club we continued to build the 13 Archimedean Solids, with Polydron Frameworks and Magformers.

My Y2 girl who got half way through a Truncated Icosahedron two weeks ago (then had to miss last week’s session) was happy to finish it. She then got her first go at Magformers. She made several of the Platonic Solids from looking at a picture of the net, then made a lovely symmetrical pattern on her own initiative.

I asked my two Y1s to build a Truncated Cube in Polydron. Once they had got the alternation correct at the start (put a triangle on one edge of the octagon, miss one edge, add another triangle etc) they were able to bring the whole solid together. They needed a little help snapping it together at the end.

My Y5 boy completed the Icosidodecahedron in Polydon, having made it in Magformers last week. My Y4 girl made the Cuboctahedron in Polydron first, then in Magformers. She built the Rhombicuboctahedron in a Polydron net really quickly, then needed quite a lot of help bringing it together. With a few minutes left at the end I gave her the Tangram puzzle. She solved it in a few minutes with no help. My Y6 girl and Y6 boy attempted the Rhombicuboctahedron in Polydron. It didn’t go quite to plan. Bob was born instead.

Here are the photos:

Y2 girl. Truncated Icosahedron (you may know it as a football); three Platonic Solids (can you name them?)

Y1 girl. Truncated Cube; half an Icosidodecahedron (to be continued).

Y1 boy. Truncated Cube; Truncated Octahedron; a Heart.

Y4 girl. Rhombicuboctahedron; Cuboctahedron; a completed Tangram.

Y5 boy. Icosidodecahedron. Really pleased with the angle I took this at: you can really see the line of reflection symmetry.

Y6 girl.   Meet Bob. Apparently he doesn’t have a best side. He looks good from every side. Hard to disagree.
