This new activity from @desmos combines some of the best pedagogical and technological features they have. I think most of us can agree that kids love marbleslides. This new activity for linear relations is like marbleslides but instead of collecting stars with the marbles, they are collecting coins. And one of the things that, I think, make it better than marbleslides is that when typing an equation in marbleslides, your equation starts to graph as soon as you type it. So you can see mistakes happening on the fly. This makes it a bit easier to guess without knowing the math. Here you have to type the equation and submit it before you see it and it keeps track of the number of trials you use. Ending the activity off is a Challenge Creator so kids can create their own challenge to share with the rest of the class. Check it out.

I had a friend of mine do a guest post on my Found Data blog. In it @virgonomic takes some data from t-shirt sales and designs from Notre Dame and collects it for analysis. It's definitely a "dirty" set of data but mostly linear and good for doing some interesting interpolating.

I have finally gotten around to creating a Desmos activity using Challenge Creator. in this case it's for students to practice the sine law while also investigating the ambiguous case. Students first investigate and then do the practice.

In this post, @mathletepearce does a good job of taking a task and showing how it could be done to different depths from grade 1 all the way to grade 7. He goes in detail on the proportional reasoning and gives us examples of student work and thinking along the way.

I have mentioned @MonaChalabi before. She is the data scientist at the Guardian and does some interesting visualizations of data. Here's a series on the participation of people of colour in outdoor sports.

My family have always thought sports are pointless and outdoor sports are just plain weird. So these numbers surprised me: on average, people of color are 8% more likely than white people to have participated in outdoor sports in the past year. The data comes from Canada and I showed the breakdown here for cycling, hiking, snowsports and climbing (each one in a different season!).
