Math Links for Week Ending Aug. 7th, 2020

Featured Links

A new resource (to me) is the website #SlowRevealGraphs. In each case, a graph is given but not all at once. The details are released a bit at a time to elicit discussion with your students. And I think anything that helps students talk about math is a good thing. You can read about how to use them here (and see all the different contributors). Consider creating your own contribution as well if you have a good graph in mind.

I like this resource about the math involved in card shuffling. And though some of the math may be a bit advanced, the general idea may be good for discussion when talking about randomness. Includes a nice interactive as well.

Suppose you shuffle a deck of cards in this silly way: place the current top card somewhere in the deck at random. How many of these “single card riffle” shuffles does it take to make the deck completely random? Clear explanation & simulations here: https://t.co/S2lQu6HNvS

Thanks to @MathTechCoach, here is a quick tutorial on using @Geogebra to create an interactive whiteboard. Perhaps something to keep in mind given all the remote learning we will likely be doing.

Thanks to @MarkChubb3, I was reminded of this quick fraction tips video from @DrCathyBruce and @ShelleyYearley. Pay close attention to the counting for correct conceptual understanding but more than that in this quick video.

Some social justice data here for your data management class dealing with Covid19 disproportionally affecting the richest/whitest vs the poorest/most radicalized.

This #covid19 graphic is gutting

Lockdown *instantly* flattened the curve for #Toronto's richest/whitest areas. For poorest/most racialized (top 2 lines), it kept rising

Today in @torontostar, we dug into @TOPublicHealth data to unearth this & more 1/3https://t.co/Gek0LckgOi pic.twitter.com/s8QppIwNvI
