I love the idea of students creating their own review activity. In this case, @MathyCathy has created a Desmos template where students each get a slide (chosen at random) to create a problem and then have to present that problem to the rest of the class. You could probably do this with a slideshow but I think it may work better via a Desmos activity. Get all the details of the logistics of doing this in the blog post

This is good both from an informative standpoint and as a great ratio/rate problem source.

Ripe with mathematical possibility!

There’s another chart in the replies that flips the ratio — from streams per dollar to dollars per stream. #mtbos #msmathchat #iteachmath https://t.co/dh2MFCjiiw
