Whoa! This "Green Sheet' review process from @SaraVDWerf is pretty awesome. What is a Green Sheet? It's one sheet of paper reviewing mathematical concepts connected to current learning. You might think "right, another review sheet" but, seriously, Sara has done a deep dive into how to use these, create your own, why they are good and even how to use them in the distance learning environment. And she has made a bunch of these and have them ready for you. I also love how she qualifies their ability to help kids also:

"I use green sheets as one of many supports for my students who arrive to the courses I teach not academically ready for the course. I have found that ALL students find green sheets helpful – but only after I have taught them how to use them and also normalized their use in class. But……If you think green sheets will magically make your students who struggle, to not struggle, you would be wrong. Green Sheets alone are not a magic bullet."

I am sure you have probably done the four 4s activity with your kids. And so in this time of distance learning I think I really like this dynamic @Desmos version that allows you to play as a class from @KenClarkson3

I can't imagine a better asynchronous math activity than this.

It's the classic "Four Fours" task, now in @Desmos w/

👉 Student avatars.
👉 Answer recording.
👉 Classroom leaderboard.

Awesome work from @KenClarkson3. #iteachmathhttps://t.co/qkqHEuQlAC pic.twitter.com/OASd33eXU5

After seeing @NatBanting's virtual session on #MenuMath, I put together this one for adding and subtracting fractions. The whole #MenuMath structure is a great way to have kids do basic problems related to various topics. Check them all out at his website http://natbanting.com/menu-math/. But here is a dynamic @Desmos version for distance learning. And thanks to @pascgall, there is also a French version.

And as an added bonus, @pascgall has also translated my Division of Fractions progression to French as well.

Une autre belle activité de traduite en français! Merci au créateur @davidpetro314 But: outiller les élèves à développer une compréhension conceptuelle ainsi qu'un algorithme pour la division de fractions. https://t.co/K130d8tzIv @Desmos pic.twitter.com/qXWBfIa08q

And finally, some great work from @Christophe_Sew in the area of derivatives of functions with negative powers. As the Tweet Says: Infinite examples with the random problem generators for instant practice. But as an added bonus he's made a collection of all of his Calculus activities here

This is quite possibly my favourite infinite fractals. And I love that it was created by @sumdumthum in @Desmos.

Read a mildly interesting paper (https://t.co/PoonBjSjCe) about a large extension of the Sierpinski Triangle.#matharthttps://t.co/PblvsbhAFo pic.twitter.com/vnM8qmaoI7

I'm not even sure what to call this but I was mesmerized.

It's so awesome that this whole animation was done in @Desmos. Perhaps some ideas for analytic geometry in MPM2D.

Viviani's theorem: From any point within an equilateral triangle, the sum of the perpendicular distances to the three sides is equal to the height of the triangle.https://t.co/aM1tkKfuaw pic.twitter.com/rBzLqcpIqc

You may love that they exist or hate that they exist but online apps that solve equations and do algebra exist. You should probably know about them at least so you can adjust your lessons. Here @MrValencia24 gives us the lowdown on two of them.

This series of images is awesome. What a perfect connection to sinusoidal functions. And if you know Ernesto, make sure you give him some props. Make sure you click through the link to see the whole picture.

@jamestanton I went to your “Circleometry” session on Tuesday and smiled when I saw this picture this morning. It goes perfectly with thinking about “where is the sun?”. Thank you for an enjoyable lesson and expanding my thinking! pic.twitter.com/zx37BnI2BV
