It's not too late to apply to the AFEMO/OAME Elementary Curriculum Project. We are looking for writers and other positions for curriculum resources and webinars for the new curriculum for grades 1-8. The deadline for applications is August 4th. So don't delay.

There is a wealth of C19 data on the Interwebs. But finding one that houses all kinds of interactives, reports, articles and downloadable data sets for most counties is particularly useful. That's what you get with Our World in Data.  And of course, there is all kinds of data on other subjects too.

Because my wife and daughters are avid fans of @RuPaulsDragRace,and so by default, so do I (don't get me started on who should have won on the last season). And so my daughter pointed out this analysis of the lip sync battles from @GaytaScience today and I was pleasantly surprised that there is a whole host of other posts about using data science techniques to gain insight about LGBTQ+ experiences. So be sure to check those out.

A couple of interactives from @DPScher made with WebSketchpad. One on adding fractions on a number line, then another on adding and subtracting fractions on a number line. Both include a video tutorial on how to use them.

I feel like in this forum, I am preaching to the converted. But just in case some of you still aren't making Twitter a part of your math repertoire, I would like to point out that there are pedagogical discussions that start with a simple prompt. Here are a couple. Make sure you look at the comments for the discussion.

I like these "If the _____ was 100 people....." data representations. And this can be used for more than just data. I think it could be used for proportional reasoning and percents as well.  This one is a few years old but it's the first time I've seen it so, here you go.

I like this "test" video on the force produced by different sized screws (he says power but he really means force). It's more of a physics video but I think you can do some math stuff with rates and slope too. And it could also be used in a STEM setting. Plus the fact that this guy has some serious manufacturing skills.

There are so many instances of bad data online about C-19 but to have an example right out of "How to Lie with Statistics" pushed out from an official state office, that's worth a conversation.

There is a lot of stuff out there about the efficacy of masks. Since there wasn't a lot of research about cloth masks for the general public before the pandemic, some are using that to attach their importance. But that is starting to change. Here @monachalabi has three (make sure you see them all) summaries of some recent research about masks (including cloth masks).

Last week the Ontario Ministry of Education finally released the new grade 1-8 math curriculum. This week they've started to release some of the supporting resources. There three short overview videos on the curriculum, learning areas and support materials but the thing I like the most is the PDF document on High Impact Instructional Practices. I am sure there will be more to come but this is what we have right now.

I feel like this post from @JStevens009 is super timely. Given that most of use were teaching online for the first time at the end of last year (and may be doing the same was the new year starts). John takes us through the mistakes that he made and whether you made these same mistakes or not, it's worth a read to get set up for the new year.

Woah, I am behind. Have you taken part in #MathPhoto20? Organized by @TheErickLee and @CarlOliwitter, this is a weekly math photo challenge. They started a few weeks ago and have a different theme each week. Check out the first few prompts and join the fun. Be sure to include the hashtag #MathPhoto20 and check out all the submissions on their website. This week's challenge is a mashup with @Anniek_p's #MathArtChallenge

I really like this post from @ChrisHunter36 on the mixed use of imperial and metric units here in Canada. I know that our official switch to metric happened in the 70s, so I was a kid at the time. I started learning Imperial then moved to metric. I also live next to Detroit so I have watched a lot of US TV. All that being said, I am pretty fluent in both measurement systems. But it seems that who ever made these adds must expect everyone to bet that way. Read on.

Well it's out. The new Ontario elementary math curriculum, that is. It has been promised for years (the last change made was 15 years ago) and although the timing may not be ideal (in the middle of a pandemic) here it is and it is to be implemented in the fall. They also have a new digital platform for distribution which I am sure will be loaded up with other stuff in due time.

We are all in a crazy state of things right now and the last quarter of the school year was not idea. But we will all be going back in the fall (in some form or another) and one thing is for sure. Students won't be prepared. So in this post, @MarkChubb3 has some tips (with the help of @TracyZager) of things to do and not to do when starting up in the September.

In this post @MathHombre lets one of his preservice teachers Maggie Eisenga using playing cards to help students practice basic math skills. It's a simple game and I think that is important. Making it too complex will be a turn off for kids. Having games like this in you "back pocket" to help students become fluent in math operations is a great alternative to worksheets.

To understand racial inequality in this city, I spent months (and months!) drawing these 100 characters for a piece in @nytopinion today. When you think about who is most affected by Covid-19, you need to consider inequalities in housing, in access to healthcare, in wealth. And so much of that ends up consistently affecting people of color. You could think of it as overlapping circles in a Venn diagram. Or, you could look at these 100 people. I'm selling prints of these on my site monachalabi.com and donating all of the profits to Covid-19 rent relief for families (a fund organised by @theconsciouskid) Huge thank you to my brilliant former coworker @aflowers85 for checking my calculations, and Jessia Ma for animating all of this with precision and creativity. Source for designing these 100 characters: US Census Bureau (American Community Survey, 2017, 5 year estimates for race age sex and disability for New York Metropolitan Statistical Area)
