Starting April 13, the DonorsChoose community is celebrating STEAM Futures Week! That means each day next week, our partners will double donations to select STEAM requests while funds last.
Get ready to share your STEAM projects!
Happy Pi Day to all, from San Diego!
Roman numerals, geometry, and a big movie studio all figure in this new blog. #mathsky #edusky #NewYear2026
That’s @oliviavidaltv.bsky.social holding a Geometiles dodecahedron as part of a story on @mathhappens.bsky.social ! More on the blog: geometiles.com/geometiles-i...
Teachers: you can get Geometiles funded by DonorsChoose! #edusky
New series focusing on building one shape— or family of shapes— at a time. Inspired by @mathhappens.bsky.social.

We’re soft launching a new set for grownups: just 48 half-equilateral triangles, but many building possibilities. Thoughts? #mathsky
So great!
The Geometiles pumpkin a patch. #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
Day 1: Link Day 2: Deviation Day 3: Polyhedron Day 4: Strongly Day 5: Digraph Sink Day 6: Partial Sum Day 7: Notation Day 8: Octagonal Heptagonal Day 9: Chi Day 10: Stellations Day 11: Orthogonal Polynomial Day 12: Monotonic Day 13: Sporadic Group Day 14: Augmented Matrix Day 15: Chord Day 16: Faithful Day 17: Wheel Day 18: Primitive Day 19: Domain Day 20: Reye Configuration Day 21: Sawtooth Day 22: Odious Day 23: Jacobian Day 24: Number Field Day 25: Wedge Day 26: Amalgamation Day 27: Bidiminished Day 28: Recursion Day 29: Hexyl Day 30: Minor Day 31: Central
Is everyone ready for #mathober? #mathober2025
I am looking forward to everyones takes, art, musing, jokes, etc.
Mathober has no rules - do 1 day or 35-or just follow along.

Beautiful and cozy!
Single seed of saltify.
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
A visit to a Caltech building that merits its own blog: geometiles.com/pi-lights-an... #mathart #mathematicalart #mathsky
Some piñata inspired polyhedra for #CincoDeMayo2025 ! #mathart #mathematicalart #mathsky
Look what the #easteregghunt turned up! #mathsky #edusky #mathart
My most recent homage to #eggs— the bottom is half of an icosidodecahedron, and the top is part of a rhombicosidodecahedron. #mathsky #edusky #mathart
Bon appetit! 🍳

It's #NationalQuiltingMonth ! What better time to incorporate math teaching and quilting.

Day 22 of #mathartmarch inspired me to make this section of a torus with a #hexagon shaped cross section. #mathsky #mathart
Day 17 of #mathartmarch entry: symmetry. This pattern is called “Night Sky” and was designed by Julie Herman of Jaybird Quilts. #mathsky #mathart
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

Kente cloth inspired pattern
African zigzag inspired cube.
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
