### Math Links for Week Ending Apr. 27th, 2018

Some major releases for @desmos today (well, really, last night at the Desmos Happy Hour). If you have ever wanted to edit a Desmos made activity or use some of the Desmos "magic sauce" in your own activities then this is your day. Everyone now has access to what is called Computation Layer. This is the extra bit of coding that is used to make some of those awesome activities and now you can play with that stuff. Warning, it does require a bit of programming knowledge but it allows some great things. But they have your back with new documentation.  But wait, that is still not all! You also get an updated geometry calculator. Now with polygons, transformations, measurement. So ramp up your geometry and have fun. So get Desmosing, what are you waiting for?

I'm at the NCTM annual conference this week so all of this week's links are coming from things I've seen. As I write this it is only Friday but if you are interested here are my Tweets. There is no way to show everything else I saw but here's a sampling

I saw @RobertKaplinsky's session on the morning of the first day and it was great to see and hear techniques on using Openmiddle.com right from the source. The main focus was on Depth of Knowledge (DOK) problems and one of my big takeaways was the idea of assigning point values to the various problems and having students pick and choose the problems they do. Check out all the resources and don't forget to look at his matrices for elementary and secondary to see progressions of DOK 1-3 for individual concepts.

There were a lot of sessions (like, a lot) so it was impossible to see them all. So I missed @mathletepearce and @ScottBaldridge's session on "Digging Deeper Into Ratios and Proportional Relationships" but when I saw @RobertKaplinsky's Tweet (from earlier in the week at NCSM), I saw that it was a mistake. None the less we can get the slide deck and info at the link below:

I got to see how @MrHonner uses Skratch to investigate probability with his students. We walked through several coin flipping, die rolling and other simulations. It was pretty simple to do and the bonus (for kids) is that they will be learning coding skills along the way. Don't be fooled by the fact that this is Skratch (which looks juvenile), you can do some powerful stuff. He hasn't posted his slide deck yet but he has some resources on his site already that goes through some of it. Eventually it will be at this link http://mrhonner.com/NCTM2018.

It' was like a freight train, seeing @saravdwerf present. By that I mean there was so much good information she was giving and it was going so fast you left feeling like you had been hit by a train. So good. The whole session circled around this slide here and ways that you could do it. The link below gets you to her blog post which (at the time I am typing this) is incomplete but she will have it all up soon. And while you are there, check out all of the other great resources on her site.

I'm not a Microsoft guy (anymore) but after going to @sig225's session on Three Technologies that will Change Math, I might start moving back. Among other things, he showed us how he uses Digital Ink with his students as a way for them to keep notes where he can monitor them remotely. Some cool tools here (especially when using touch screen tech). Check out his notes at the link below and the live doc he used here https://tinyurl.com/nctm18onenote

I saw @MFAnnie's talk on Sense Making with students. I have seen some of this before but I don't think I can get enough. I am constantly blown away on how easy it is to tweak what you are already doing in class so that it allows students to think and make sense more. Below is a partial video of some of the ideas in another talk (to give you a sense) and the link below will get you to the entire slide deck of the talk I saw.

I tweeted a lot and had lot's of images of slides, you can see them here but below are just a few of them.

When @MJFenton called an audible and changed the focus of his session away from the topic of The Five Practices, I was disappointed. However, he still scored a touchdown with his deep dive into visual patterns. My favourite take away was the technique he used of only showing one term at a time and continually asking "draw the next term in the pattern" rather than show all three terms immediately. There is so much more space for students to dive in this way. Try it out.
