I have been doing some work on MHF4U this week and creating some Desmos Activities. This is the first, it is a card sort that students would do after being introduced to rational functions corresponding to linear and quadratic functions.

I like this activity from @AndrewStadel on angle relationships of transversals and parallel lines. I have one looking at the similar relationships but using a GSP websketch instead.

One more from Desmos. This time from @ddmeyer and the rest of the team showing off some of the features that are only available to them. Those tools that react to what you've done (in the graphs and typing) are slick. This time they are about scale diagrams. So if you are doing anything with ratios then this might be a nice little activity.

I like this new hashtag #SmudgedMath from @pgliljedahl. The idea is that math problems are shown with some things "smudged out" with a question like this one "Can this set of equations have a solution?". Try some on your own or start with some of his.

In the new book "Weapons of Math Destructions" @mathbabedotorg looks at the good and the bad of how algorithms affect our lives (it seems the book is about mostly the bad). Listen to this interview with her where she talks about some of the examples. Listen at the link below.

Oh yeah, I almost forgot. Desmos activities can now have MC questions in them. So there's that

Connections between the geometry of simple shapes and movies. Thanks to @GeometryMatters for this one

I have been playing around a bit with animated gifs. I'm still figuring out how to get the quality better but here is a couple I did this week. One is on rotations of points and the other is on reflections.
