@ddmeyer did a short online session and in it he showed some ways to Desmosify some standard math questions. Check out this slow reveal of the mystery shape. Then you can download the actual activity with all the examples and watch the video of the webinar for the rest of the surprises.

As the we start the new year in Ontario, if you are teaching elementary math, then you know that we have a new curriculum. So it would help if we had help figuring it all out. Some of the webinars offered by the ministry, I've mentioned before and can be found here ontario.educatorwebinars.ca. But there are now other webinars scheduled. These are developed by teachers for teachers in conjunction with the OAME & AFEMO and you can sign up here

You can always count on @MathEqualsLove to share some good stuff. This time she's sharing puzzles and giving some advice on how to deal with them when we are in the era of C19. Some of them require manipulation but others are as simple as manipulating numbers. Check out all the downloads at the link below:

I think that now more than ever we need to try to find ways to shake things up (literally). That is, whether you are teaching fully online or teaching face to face but have to be socially distanced from your students while still being in class, Well, @SaraVDWerf has been doing some work on Instagram to help give you ideas on how to get kids (and you) to move. If you are on Instagram then you should follow her. She has been posting some idea videos on her story and you can see past stories on her page. But if you aren't on Instagram, you can still go to her blog and see her post on movement.

It's interesting but I don't think I have ever really thought about whether I ask students questions that have a morally wrong answer. That is, a question like "did you do your homework?" means the student is "good" if they answer "yes" and "bad" if they answer "no". Read more from @DavidKButlerUoA

In the new Ontario math curriculum, mental math is explicit (which is good) but some people may think that that means kids need to memorize stuff (which is bad). In this video @JamesTanton gives us some ways to make internalizing the multiplication table more than just a memorization exercise.

If you are looking for some help preparing for the new Ontario math curriculum then @GLewisOCT has done some work. In the slideshow, on his site (from a workshop that he did in the summer), there are a lot of resources to help but the stuff I like the most is his comparison of the old curriculum with the new. Check the slideshow out.

Here in Ontario, unless you have been living under a rock, you know that there is a new Gr1-8 math curriculum. And seeing that it is supposed to be implemented this year, there are many who are wondering "how do I do this?". Well the workshops are starting and, depending on when you see this, you may still have time to sign up for the first of many workshops to help get ready.

This week (on Thursday) I am presenting at the ECOO Camp virtual conference. Just a quick tutorial and introduction to using Desmos Activity Builder. But if you are interested, take a look at the other tech based sessions. I am part of the STEM section but there are other sections that are more general uses of tech like Wellness, Equity, Digital Pedagogy and more.

There is a lot of uncertainty about C19 deaths. There are stories of people dying of all manor of illnesses and being counted as a C19 death. Those who are C19 deniers try to use this as evidence that this is all a hoax. But the reality is that counting deaths related to C19 is complex. However, a better way to get a gauge on the number of C19 deaths is to look at the excess deaths. As it turns out, the yearly/monthly death rates in each country are fairly steady. So the excess deaths in any time period can be attributed to some anomaly. In this case it's C19. And in actuality, the thought is that the official C19 death count is probably an undercount. Anyway, here is some data on the excess deaths by race.

Recently Desmos has made it so that you could share teacher dashboards so that if you wanted to team teach an activity, you could do it. Now they have finally set things up so that you can actually collaborate on the actual construction of the activity. Though you can't edit the activity at the same time, you can both be working on it.
