Lot's of talk about Ontario's new destreamed Gr9 Math Curriculum. So I thought I would share this summary from @MakeMathMoments which includes this really informative video from @Jason_To on the history of streaming in Ontario. Even if you are not interested in the upcoming Gr9 destreaming, the video is pretty interesting. You should also check out the panel discussion from OAME that Kyle and John hosted with @Jason_To, @Pi_lab, @HKhodai and @MarkChubb3

I wasn't sure that I was interested in Taxicab problems but when I saw slide 9, I changed my mind. This really could be suitable for all grades.

I created a @Desmos activity to introduce students to taxicab geometry. A fun little activity that shows students an example of an easy to visualize non-Euclidean geometry. #improvemyAB #iteachmath #geomchat https://t.co/7IIADQRJdB pic.twitter.com/nUIckOa5Yd

This is part of a five video series from @YRDSB but (of course) I like this one the most. 5 Barriers in Math We Need to Disrupt and Dismantle. Be sure to click the link in the description to see the other videos. Thanks to @RoyanLee for pointing this one out.

I am not a fan of math "tricks" and I suspect neither is @Howie_Hua but that doesn't stop him from posting these TikTok videos of why math tricks work. That's where the important stuff is, not the trick itself but why it works. So watch his videos and then recreate them in your classeswatch the ✨ series premiere ✨ of Queens of Cosplay, starring the illustrious @onlinekyne 👇 pic.twitter.com/brzojzjGNu

I really think you can use this sort of thing as a math starter in class, in just about any grade where they know what a prime number is. It really is a beautiful result.
