Pattern block play! #21CenturyPB #iTeachMath
The main image in the top left shows a radial design created with 21st Century Pattern Blocks. It was built by arranging six regular hexagons around a central hexagon. All seven hexagons share the same composition and have 4” sides. The first image along the bottom shows a scaled-up equilateral triangle which is used to create the regular hexagon (with 4” sides) shown in the second image. The triangle is made of 1 yellow hexagon, 1 purple hexagon, 2 green triangles, and 2 pink triangles. The three images on the right show the progression of the design.

My 6yo asked me this morning:

"If 0 + 0 = 1, would 8 times 0 be 4?"

I wrote a blog post about it.

I love working with figurate numbers (see my Square Numbers handout mathinst.com/squareNumbers) esp. Triangle Numbers w/my students but never thought of @mathforlove.bsky.social's 'Step Numbers' (mathforlove.com/wp-content/u...) which now seems obvious to consider! #mathisfun #mtbos #iteachmath

Just in case any of you think my manic enthusiasm for the artistry that is Outer Worlds 2 is exaggerated...

This is ONE of 20+ fully original songs I have heard so far on the 3 in-game radio stations you can tune into as you play.

Did you know completing the square literally means to complete the square? I didn't when I was in high school and that would've made it so much easier.

Just arrived in Atlanta with these new shoes that I designed using Tile Farm studio. The tessellation on them is related to the truncated squares Archimedean tiling. If you come by the Tile Farm booth at @nctm.org this week I’ll show you how I made them!

From #RaceToNowhere to #CountedOutDoc, one thread connects them all: how belonging and self-belief shape mental health.

On #WorldMentalHealthDay, let’s design systems that nurture confidence, curiosity, and connection so no one feels “counted out.” 💚
