Just in time for Halloween, @Desmos releases two new activities, one for solving inequalities and the other on plotting points to create an animated pumpkin. They were released at the most recent Desmos Live - see video below

I think any time that you can contextualize math in a way that connects to students then you are probably on the right track. And so if you are working with cylinders, then you might like this task from @MrAspinal connecting cylinders to Super Mario. Have fun

I was reminded of this video this week. It's a great connection between coding and mathematics and with the new Ontario math curriculum's inclusion of coding, it seems like it's a good fit. Though some of the math moves into high school, it could easily be used in elementary to spark interest.

It's Global Math Week. For the last few years, lead by @JamesTanton and @GlobalMathProj, teachers around the world have been on a mission to spread joyous mathematics to their students. This year is no different and starting Oct 10 (10/10) we hope that you will bring the idea of Exploding Dots to your kids. Check out the website for all the activities.

Just a reminder that, maybe, understanding data management is more important than calculus. And although there have been some concerns with the group Levitt got together for this for not having enough actual teachers, I still pretty much agree with the sentiment.

It's now time for me to shamelessly plug the podcast that I do. This is the third year that I have taken speakers from the OAME conference and interviewed them about their sessions and it is still not at all like work. This season we have @PeterTaylor&@Pi_Lab, Ian VanderBurgh, @TaraCFlynn&@ShelleyYearley, @RooSloan and starting off this month we have Ron Lancaster talking about his session "A Shared Problem Solving Activity". On the podcast episode he doesn't divulge the activity he's going to do but did a similar type of activity that has a low floor and high ceiling with a surprising result. You can register for his webinar at our @OAMEtalks website

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.
