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.

A couple of nice multiplication puzzles from @JamesTanton, One with multiplying fractions the other with multiplying whole numbers made of ones. Both with surprising results. Have your students try this to get your classes going.

As always @MonaChalabi does a great job of visualizing ideas that revolve around social themes. In this case it's characterizing the demographics of people in NYC. Make sure you swipe get all the images.

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)

I always like @JessicaHagy's graphs to help talk about related variables. In this case, this relates to my fascination with jumping ramps on my bike as a kid
