We’re soft launching a new set for grownups: just 48 half-equilateral triangles, but many building possibilities. Thoughts? #mathsky

This is an entry for the 3rd day of #mathober2025 (polyhedron) and also the 1st day (link). It is a variation on a rhombicuboctahedron with a projection of the Borromean Rings. #mathober #mathsky

This jumbo size dandelion is called a salsify, to the best of my knowledge. The tiny broom is a single seed. The “heart” has Fibonacci spirals. Could the spherical looking flower be a spherical Fibonacci mapping? Seen in North Rim, Grand Canyon NP. #mathsky #Fibonacci

Celebrating #nationalquiltingmonth with two classic quilting blocks: the Sawtooth Star and Dutchman’s Puzzle. Geometiles allow you to create these patterns quickly so that you can focus on their geometry even if you don’t know how to sew. See Geometiles.com/quilts for examples. #mathsky #edusky

Celebrating this year’s Pi(e) Day with this fluted number! It comes with its own pie stand, made for the occasion. Watch video to see how two flat surfaces come together to make the pie— or should I say PIElyhedron?? Mobies make the thin pedestal of the pie stand possible. #mathsky #piday2025

Wait for it… this 7 yr old is discovering a new way to play with Geometiles. He’s treating the chain of rectangles as a multi-hinge system, and he finds it “satisfying” to experience the system unfold from a triangle to various other shapes under the effect of gravity. #edusky #mathsky #iteachmath

This #BlackHistoryMonth I’ve been looking at the origins of African American crafts. The pattern in the first picture is inspired by Kente cloth. The cube design is based on the zigzag pattern often seen in African art. #mathsky #mathart #mathematicalart
