NEW VIDEO: The Progression of a Number Line in Grades K-2. https://t.co/wBupS5q6TU #iteachmath

[Graham Fletcher @gfletchy]

It was a labor of love, but I finally finished creating eight new progression videos. Once they're out, I'll get them uploaded to my site. Thanks for the nudge to get these done. https://t.co/NAoUN3Q5hX

Are you a K-12 teacher interested in learning about Desmos tools? Then you don't want to miss the session on "Desmos Playground" presented by @MsBeckerMaths @SimonSaysMath #miniconference #treatyourself

[Tyler Vigen @TylerVigen]

It's new, it's improved, it's got AI-generated explanations for why everything correlates. Today I'm launching the new Spurious Correlations: https://t.co/GQ234iJyBR

When using custom colors in @Desmos, RGB felt straight-forward enough, but I didn't have a clear grasp on what each component of HSV did. Turns out that it's much easier to visualize in 3D.
