@anniek_p @Desmos Sorry all, I tried out the referral link, but maybe it's a one time use thing! Thanks @MrCorleyMath !

@anniek_p @Desmos Annie, I learned a ton on the forum, https://t.co/851sN1dDcp

My work this year has pulled me away from doing CL level stuff, but the people on the forum are super helpful!

[Zach Armstrong @aethirv]

I've been REALLY digging into @Desmos CL with help from the wonderful forum here: https://t.co/oa7SUBai1W

They are working on a structured workshop to help learn!

Write a linear equation in function notation from a table. Auto-generated practice problems, 3 scaffolded levels. https://t.co/qJgnH7qxLJ

I've been loving digging into the @Desmos computation layer!

Update: I figured it out! That activity can now generate endless practice problems.

Slope-intercept equation from a graph. Auto-generate with integer y-intercept and rational slope. Students led through writing an equation. Any variation on slope-intercept. Anyone know how to reset all components of a slide for endless practice? https://t.co/aHUr94SGGp

Directions on a graph. Students can choose the "addresses" of two buildings, figure out directions between them, then connect that with slope. I'd like to add on to scaffold toward "graph a line with this slope and this point". https://t.co/kROTUFDmMI

It's much easier when they just openly wear swastikas. Stay safe all and focus on the good work.

Hello everyone - after a long time, I found what I was thinking about. It's still in alpha, but it seems like there's so much potential here during this time, especially: https://t.co/sZgryrtxzR

I saw a "new" platform for students to work in groups on Desmos (and other platforms) at MCTM2019, but I can't find it in my notes or in a web search. Anyone have a clue? Thanks! #MTBoS #MCTM #MCTM2019 #NCTM #iteachmath @orcutt_ariel
