Just tried @nhighstein's Desmos activities on Voronoi Diagrams! Wow. https://t.co/wU1ybB4X08

I've been having fun writing fairly compact code for VDs.

@pwharris Enjoyed the over podcasts. HS teachers may think it's too arithmetic? Couldn't completing the square be understood as an over strategy? #mtbos

[Steve Heller @SteveRides]

I've been having fun proving and creating trig identities like this one: tan x + sec x = tan(x/2 + pi/4) #MTBoS #iteachmath

[Steve Heller @SteveRides]

@pwharris Just listened to the podcast on addition using factoring. EVERYONE DOES IT! How many ways do you think of 700-300? Most people, I suspect, will respond effectively with (7-3)*100. Factoring to add, no?

@abeliangrape_ Yikes! I hope this week is better!!

@mathigon just brought text URLs to life! #MTBoS

[Steve Heller @SteveRides]

@Mathigon Is there a reason groups cannot be flipped? 3-click workaround (& proof of concept): ungroup-flip-regroup. I just ran into this again encoding one of Lee Sallows' amazing Geomagic Squares. Or allow disjoint merge (harder) https://t.co/v5BpUFOfIJ https://t.co/Qdx1ifT7jQ

@davidporas @MathigonOrg @desmosclassroom @Amplify While much improved, it is still buggy. When I try to edit the bottom text on this fixed-size canvas, the toolbar gets in the way, pinned or not. https://t.co/B34LLid5J9

[Steve Heller @SteveRides]

I started to recreate the page, and it got wedged similarly. Perhaps something I'm doing is tickling a rare code path???https://t.co/B2riwflAuy

[Steve Heller @SteveRides]

@MathigonOrg This utility (very important) page is in a bad state, so I can't interact with it; I can't see it all to recreate it easily (actually a lot of work), and I can't copy the contents. https://t.co/hNY7JyMxfg

[Steve Heller @SteveRides]

@MathigonOrg I tried the logic section. Sometimes after a save and then a restore, "wires" vanish. Here's an example canvas and a before and after restore pics. https://t.co/9oCPETqqmM

[Steve Heller @SteveRides]

@mathigon Students love changing colors, for (map) coloring of tilings, nets to be folded, or just objects. It currently takes lots of clicks & mouse motion. How about adding the ability to keep the color palate open, & maybe even pin it to the selected object like the toolbar?

[Steve Heller @SteveRides]

@davidporas @MathiGon Sorry if this is a retweet ... How about a colorblind-friendly palate?

[Steve Heller @SteveRides]

@mathigon: I really like grouping! I used it here to decorate colored shapes to provide "texture" to help colorblind people distinguish colors. I wonder if having built-in textures would assist the colorblind. #iteachmath #MTBoS https://t.co/XYaNJ8nqCJ

[Steve Heller @SteveRides]

@davidporas @MathiGon Thanks, David! A more straightforward enhancement might be to have colorblind-friendly palates as options.

[Steve Heller @SteveRides]

@KiranABacche @jamestanton @GlobalMathProj @dhimath_india Nice! I know these as staircases: https://t.co/szoUEvF6Nz

[Steve Heller @SteveRides]

@MathigonOrg I'm experimenting with decorating colored arrows with shapes to make them more colorblind-friendly, and the page was suddenly wedged. System being updated (maybe temporarily)? @davidporas https://t.co/BKq2UcTLHb --- the Twitter image is the one I expect

[Steve Heller @SteveRides]

@davidporas @MathigonOrg Thanks, Dave. It will be a very cool and hopefully effective part of "discovering" Pick's Theorem.

[Steve Heller @SteveRides]

@MathigonOrg Does Polypad have a way to communicate the area of a custom polygon? @davidporas #iteachmath #mtbos Thanks!
