I have been sitting on this activity for a while. I actually made it last December but just got around to posting it now. We have started to develop a number of activities using a continuum model for student practice where the practice problems become incrementally more difficult as students progress (at their own pace). In this case we've tackled trig identities. Take a look.

I like card matching activities because they get students to do the math but in a way that is much more palatable for students. In this case @marybourassa (adapted from @pamjwilson) has students match up different representations of linear functions (points, slope, equations, graphs) and students have to match them. We did a similar activity with functions in context here but this one is good for analytic linear functions.

There is no shortage of questions you can ask about the Tim Horton's Roll Up the Rim contest. This time @mathletepearce has turned it into a 3Act Task on Probability.

Some evidence as to why you can't just look at the summary statistics for data sets without looking at the visual representations. In the spirit of the Anscomb's Quartet (my post here), here is a number of data sets that have the same summary but different graphs. Don't miss the Datasaurus too.

This is a fight we have all the time. That is, the notion that students come into your class thinking that they are not a "math person" or the societal idea that it's even OK to claim you are not a math person (yet they would never say "I don't read"). Thanks to @michelecooper for this one.

And along the same lines is this TED talk from @MonaChalabi on Three ways to spot a bad statistic.

Sometimes examples of math are right under our noses. In this case, it's an example of a dilatation that is seen every time the Twitter app opens. Get the video or animated gif at the folder below.

And we might as well start the summer with a math joke about math jokes. Very Meta.
