Math Links for Week Ending Aug. 18th, 2017

This will be an abbreviated math links because I am up north cottaging with very little Internet access (or electricity for that matter) but it seems fitting that since it is close to the beginning of the school year (at least here in Ontario) that @RobertKaplinski has a short post about setting up classroom norms.

Here's a nice little Desmos activity dealing with transformations. Although the notations used doesn't quite match up with Ontario curriculum, it shouldn't be too much of a stretch for our grade 7&8 students. But the concepts of transformations should be easier to deal with with these visual examples.

For a while @Desmos has been teasing us with their geometry app but it wasn't very useful because you couldn't save anything. Well now you can. Just log into your @desmos account and save away. Next step will be to make it available on Teacher.desmos.com.

A few more links left over from last weeks Twitter Math Camp. One of the flex sessions was from @jgough on how she uses sketchnoting. Below is her summary of @Gfletchy's keynote. Check her Twitter feed out for more like this.

In my morning session I was introduced to this nice whiteboard activity from @kellyoshea. The simple premise is that students are given a problem and asked to write a solution that has one intentional mistake on a whiteboard. Everyone else plays the "Mistake Game" to find the mistake. See all the details at the link below. Thanks to @Stoodle @PiSpeak for this one

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.

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.

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.

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.

Math Links for Week Ending July 21st, 2017

I love this series of dynamic sketches on exterior angles from @dynamic_math. It's the visual nature that I like the most and the fact that you really get the idea of the fact that the sum is 360 (regardless of the polygon). I have done something similar here using Geometer's Sketchpad (I should turn it into a websketch) but I think I like the way this works better.

I can't decide whether I like this or not. In some ways it reminds me of the old MathBlaster type games where the math was embedded in a game that already existed but as I played this Tetris game with embedded factoring, I just wanted to play more. Maybe that's because I used to love Tetris. Thanks to @ddmeyer for pointing this one out.

The idea that when you have student centred learning leads to pushback from students is not new. In my opinion a lot of that comes from students who find it easier to just be told what to do. I don't think they are actually learning better in that traditional setting but students like it because it is so passive. When you have student centred learning, they actually have to work. None the less, I like this sketchnote from @Wheeler_Laura on the topic. Follow the link for more details.

I'm a sucker for anything about primes. Here's a new @Numberphile video talking about the distance between large primes. I was particularly interested in the algorithm for showing the distance using factorial notation. But the crazy logarithmic expression in the proof is something that should turn any grade 12 student's head

Math Links for Week Ending July 14th, 2017

I have liked @Desmos' Polygraph from the get go. So it seems odd that it has taken so long for someone to take it offline. In this case it is @Mr_Stadel who has come up with a nice hack to do them online. And all it requires is some plastic sleeves and whiteboard markers. He's done Lines and Parabolas so far. Why not add your own?

More tips from @Mr_Stadel on using Polygraphs in class. This time it's using the idea of a word bank to help students (and a list of "taboo" words that students cannot use). The idea is to help students use more academic language while using Polygraphs.
