Just as we began talking about Rotational Symmetry, this came on the news. What a perfect example of math in art. Students were in awe of this artist’s work, and it went well with the optical illusions we were discussing in our #ocsbMathUp lesson #ocsbMath https://t.co/vP2Oc7hQmv
A Mathsy version of wordle?

So last week I took a photo of some boxes of potato chips and when I was back at the same shop, I took another photo—can you see the difference? And what difference would it make if I buy some now?
Have been noticing lots of #HalloweenMath 🎃
I wonder...how many boxes of potato chips altogether? How could we figure that out? What would be a reasonable estimate for how many little chip bags in each box? In all the boxes altogether? What would it cost to buy all these boxes?
So I just took a photo of a page in a children’s math picture book—the entire book focusses on the ‘differences’ between squares and rectangles...can you see why I wish there was a monkey facepalm emoji? #mathmisconceptions@SACDavidson
