I have always been a fan of MC Escher so this dynamic Escheresque tiling by @GHSMaths is super awesome. I have created my own dynamic sketch where you could make your own tessellation here but this is just way more attractive. Make sure you click on the link in the Tweet so you can get the original Desmos sketch.

Here is a nice little dynamic sketch that demonstrates this interesting geometric property. Take a quadrilateral and create similar quadrilaterals on two adjacent sides and keep doing that and, as it turns out, those two lines of quadrilaterals will always spiral towards each other. So @dpscher has made a dynamic sketch to show it works for all quadrilaterals. Check it out at the link below.Curriculum tags: Gr7, Gr8, MPM1D, MFM1P

If you like @SteveWyborney's Splat or Estimation resources then you will like this newly released content for 20 days of Number Sense and Rich Math Talk. In it he has 20 new activities and each could be used in a grade k all the way to grade 12 class (depending on how you use it. It's all new content so there is no need to worry about overlap if you are already using his stuff. And if you are not, you should be.Curriculum Tags: All

It's time for @ViHartViHart's 9th annual Pi Day video and even she (purposely) makes a mistake it's just fun to hear her say "...that words are just sounds made out of our vibrating meat flaps...".
