Math Links for Week Ending Mar. 11th, 2022

A worked example is the bread and butter of a math teacher and it has been for years. Of course, if you are heavy into the  Thinking Classroom then you might not think so anymore but I think that this post about how to make kids think while still showing worked examples starts to create a bridge between a traditional and a thinking classroom.

We all can think of teachers who just talk talk talk talk while boring everyone to bits. That's bad. Meanwhile, research in favor of explicit teaching piles up.

What sort of explicit teaching actually works? Here's an essay where I make sense of this: https://t.co/nWKFooeWBf

As I do every Pi Day (week), I feature my Pinterest page that houses all of my Pi Day resources. Videos, images, activities, etc.  And I always highlight that the Rolling Stones logo has Pi right on the tongue.

I like the idea of visually seeing the effects of the positions of the points on the standard deviation and this interactive from @TimBrzezinski does that trick

Standard Deviation: Quick intuitive intro and exploration. Here, the length of either pink arrow represents the SD of this data set. What do you notice? What do you wonder? https://t.co/FL9AG5DxRT @geogebra #MTBoS #ITeachMath #statistics pic.twitter.com/qvbFUYGrWU

I love this activity that combines some of the mechanics of Pascal's triangle and adding polynomials. I could see it used for other polynomial related operations too.

I was in a Grade 9 class on Friday and gave them this task which gave them lots of opportunities to show their algebraic thinking. More details in this blog post: https://t.co/JGgzMRKXaX pic.twitter.com/QzCGFDckyg

Swapping the position of faces and vertices in a polyhedron creates its “dual.” Here you can see that a dodecahedron and a icosahedron are dual. What is the dual of a cube?

I have seen many versions of this clock but not with 9s yet.

Amazing clock made of all 9s. Source: https://t.co/SYy9RiDSu4 pic.twitter.com/1UwKBZL6N5

This seems to go hand in hand with the above clock of 9s

I *think* I created a new puzzle?

(a) Find expressions that equal 1 through 10 w/out moving anything. Each expression needs at least 2 numbers in it.
(b) Create an expression where you can find expressions equal to 1 through 10 in it. What's the least number of numbers needed? pic.twitter.com/j3mdcs8UFj

Fibonacci and Nachos, of course
