Math Links for Week Ending July 28th, 2017

I'm currently at Twitter Math Camp 2017 (which goes until Sunday) in Atlanta and so this week (and next) will probably have mostly links links from the stuff I've seen. You can see the program and get to the Wiki by following the link below. And because it's Twitter Math Camp, the Twitter feed for the event can be found by following the hashtag #TMC17

So before TMC17 we had Descon17. That is,  the Desmos PreConference. Here a good chuck of the @Desmos crew were in town to show some of the latest stuff they are working on. I was thrilled to get help fro @Eluberoff on an activity I was having trouble with in the working session. You can get some of the resources from the breakout session at the link below. My favourite was the Beginner/Intermediate/Advanced scavenger hunt. So good to hone your Desmos Calculator skills.

One of the repeating sessions is something called My Favourite. Here people get up and do a "show & tell" of something short that they like. @samjshah had a neat idea of having students ring a bell when they have accomplished something to be proud of. See his slide deck here and read the speaker notes to get the gist.

In @Jstevens009's My Favourite, he reminded us of all the ways that people on the Math Twitter Blogosphere (MTBoS) can share out their stuff.

I went to a neat session from @mathgeek76 on developing calculus topics in early elementary school. The neat connection that algebra was for when we had straight surfaces and calculus was when there were curved surfaces (IE real life) was pretty cool. I got some neat ideas on ways to simplify calculus concepts.

The main session that I did was with @zimmerdiamonds on Podcasts for math. You can get the slide deck here but if you want to have a more comprehensive list of podcast episodes, I have finally compiled them at the tab above. Happy listening

One of the neat features of TMC is that the morning session is a two hour session that continues over three days (so 6 hours total). So you can go deep on one particular topic. The one that I chose was about getting students to talk more (and you talk less)  in class with @stoodle and @PiSpeak. Lot's of prompts to get kids talking like debate protocol and more. Check out all the slides and links below and follow the hashtag #talklessAM for some of the work and discussion that we had.

More stuff on what research tells us is good for math class. Thanks to @MrEsping_math for this one

I thought @gfletchy's Friday keynote was pretty good. You can see it all below

I did a My Favourite too on some of the dynamic web sketches I have been making. They are all in one place and are meant to be little short things your students can do to practice skills.

The My Favourite right after mine was by @JoelBezaire and he mentioned CODAP. This is a free online statistical analysis tool that has connections to Fathom. So for anyone who is missing Fathom (it is basically not being supported anymore), this is the potential replacement. I can't wait to start to try this out and report back on how good it is.

One of my web sketches was for making dynamic Escher Art. Thanks to @trianglemancsd we now know where you can get custom laser cut tessellated things made.

Even though this is a Verizon commercial. The message is still pretty good for math & science students. Thanks to @KMarkPet for this one

In one of the @Desmos sessions, they showed some new features. Hear @jreulbach give's two quick screenshots of them.

And, of course, in the off hours we constructed things like hyperdodecahedrons

Some tips on why it's important to learn math. Thanks to @KMarkPet for pointing this one out.
