Math Links for Week Ending Jul. 23rd, 2021

Featured Links

Last week we found out that there was some language removed from the new Grade 9 Ontario Math curriculum about being culturally responsive and dealing with equity. Check out last week's post for more. This week, here are the responses from the OAME and the OMCA. And again, if you are not OK with this, contact your local MPP.

I have said it many times that I am a fan of matching activities. This one comes from @MathEqualsLove, someone who is no stranger to matching activities. In this case it's a twist on a worksheet with complex exponent simplification questions. Here students have 20 expressions to simplify to match up with one of 4 simplified expressions. Read on for more info and the downloads.

Speaking of equity, the folks at Desmos are very committed to their equity principals. And if you have ever use their activities in Anonymize mode, you know that students' then get renamed as a current or historical mathematician. Well they have just updated their list to be more inclusive than it already was and you can read about their thought process (and see the entire list) here.

You can count on @JamesTanton to give us examples of beautiful math. In this video from 5 years ago, he shows us how making things visual can make things more visual with this problem that starts with an array of dots.

With new "y" algebra tiles on Polypad at @MathigonOrg, Ts can easily create systems of equations for Ss to explore. Here's one approach to a solution. The Polypad is at this link: https://t.co/lR5tX0Gzym. See the next Tweet for how to create a system like this. #iteachmath #mtbos pic.twitter.com/oPnrIpQaNT
