If this wasn't already the case when we started the year last year (because of our end of the previous year lockdown), it's probably more the case now. That is, the idea with @DDMeyer's post on advice on how to handle the fact that students may be coming into our classes this year on the deficient side. So I appreciate the analogy to "Previously on..." TV shows.

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.

If you follow Ontario math at all this week then you know that a bomb dropped in the area of equity and culturally responsive curriculum. That is, somehow, some of the language about these things that was in the front matter of the new grade 9 curriculum was quietly stripped out. However, people noticed. You can see exactly what the changes were in this Tweet and the associated comments (some of the comments further down the list as well). And even though this directly affects the current Gr 9 curriculum, this really affects all future curriculums. Let your local MPP know that you are not OK with this.

If you are teaching any math concept, there is better anchoring for students if there is a story associated with it. My guess is that if they hear this baseball related story on a recent episode of @PlanetMoney they will come away with a great anchor about compound interest. It's good for just introducing the topic or more complex calculations involving annuities and pension payouts. Here's the short version: Pro baseball player Bobbly Bonilla gets the last $6 million of his contract bought out in a way that after 10 years, he gets over a $1 million a year for 25 years.
