I had a fun season recording the @OAMEtalks podcast and in the last few bonus episodes we were talking with some of the featured and keynote speakers from #OAME2021 and I asked each of them what they thought was working well with online learning. This episode is what they all said:

If you use a proxy for a high-emissions grid, though, the picture changes substantially.

Function Carnival lives on! https://t.co/IMs7ghLcRd. Rebuilt in Activity Builder so that it now has all of our new features (snapshots, pacing, anonymize, assign-to-classes, etc). Also means you can now see behind the scenes and copy-and-edit.

I really appreciate the time and care that @standupmaths puts into his videos. It's clear he must have done a lot of takes to get some of these shots and even though this may be a bit long, there is some great stuff here about probability and the binomial theorem plus if you have any kids interested in Minecraft then this might get them geeked.

I have to say that I am thrilled to see @Desmos redo Central Park. This was the activity that sold me on Desmos activities but it was built before Activity Builder was a thing so once AB came to be, Central Park couldn't take advantage of all the features that we now love about doing an activity with Desmos (anonymize, pacing, snapshots etc). So enjoy the new version of Central Park and watch the #DesmosLive to get all the details (including a glimpse of some of the original storyboards)

One of the things that @Desmos has done is try to go beyond math by including things like checkin screens where students can say how they feel. And, of course, that means other people will start to make their own. So I love this checkin screen from @Kristen_Faust where you get to answer "Which Sloth Are You?" Add it to one of your activities today
