Here is a short activity that I created with Desmos to have students practice with interpolation and extrapolation. It uses some of the new Draw features as well.

There will likely be a host of Olympic related math resources around the Interwebs but I like this if you are looking for an introduction or review of Order of Operations. Here the Romanian soccer team puts math expressions instead of numbers on their jerseys.

And speaking of Order of operations, I really like this Desmos Activity created by @mathycathy that uses order of operations and the Draw feature. The original post was  from @mathequalslove about these Twin Puzzles is here, but the Desmos version is pretty sweet and simple. Also included in the original post is a couple of other types of puzzles. One dealing with area and the other dealing with geometric shapes.

In grade 9 we talk about optimization. As it turns out there are reasons you may not want to optimize when it comes to consumer goods. This might be a nice addition to any lesson this topic. See the link below for some explanation or just watch the video

I love this new (to me) Reddit feed about beautiful data. You can find it on Reddit or on Twitter @DataIsBeautiful.
