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.

In just 15 days the total number of #COVID19 cases in Georgia is up 49%, but you wouldn’t know it from looking at the state’s data visualization map of cases. The first map is July 2. The second is today. Do you see a 50% case increase? Can you spot how they’re hiding it? 1/ pic.twitter.com/wAgFRmtrPk

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.

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.
