I've been sitting on this post for a while. In my quest to find all kinds of data sets that students can use for analysis, it's always fun to find one that is interesting in some way. This one isn't a particularly interesting data set (its a very linear set of data) but it's origins are fairly interesting. I got it from a 3Act Task that @Gfletchy did. I probably would do the 3Act Task first then have kids analyze the data. I think the best questions you could ask is to check whether she keeps the same skipping rate throughout the whole 30s of skipping. Check out all the data and the original video at the link below

I'm a big fan of cardsorts for kids to practice skills. In this one @TypeAMathLand has created a Difference of Squares, Perfect Square Trinomial, or Neither Sort. Clearly this is a labour intensive creation to come up with the equations but she has done all the work fo you so just print it out, cut it up and you're ready. Thanks to @mathequalslove for pointing this out.

This is such a nice visualization from @anniek_p on the connection between the unit circle and the sine curve.

Here is a great 5 minute Ignite talk from @MathMinds where she talks about the importance of thinking of our lessons more like a mathematical story. Thanks to @MFAnnie for pointing this one out.

Some conservation of momentum calculations from @standupmaths in doing this classic physics problem. Perfect for any solving simple equations curriculum.

Thanks to @Gelada I now know that sometimes you can't tile the plane with some shapes but you can partially tile the plane and that can be described by a Heesch number. And as an added bonus I would check out his geometry based colouring books (with @alexbelos)

And as another added bonus from @Gelada, check out the cool way these shapes unpack.

I see parabolas and circles, what other math do you see? Check out the thread to get the actual Geogebra sketch.

Here's a great way to visualize those 3D trig problems. Thanks to @mathequalslove for pointing this out.

I particularly like the little touch of the "frowney" Amazon boxes in this @MonaChalabi infographic
