"Building #thinkingclassrooms is a problem to solve, not a formula to master.
The framework gives ideas, not a choreographed dance to follow.
The best tool to solve the problem is recursion - find your efficiency and scale it up."

Had an awesome three days with @pgliljedahl presenting to cross curricular T’s, then to Teacher Coaches and finally to math Teachers.
Lots of new stuff and deeper learning.
4 school boards-around 325 people.

“You actually cared to teach us the theoretical cognition behind the mathematical content, in a way that was accessible to students who weren’t necessarily inclined towards STEM. I really appreciate that.”
Someone cutting onions-must be my old age!

I’ll add to watch. Listen, collaborate, connect, justify, represent, build, engage, observe, question, discuss and challenge-THE MATH.
Thank you @pgliljedahl for all your work in the math world!!!
A Game Changer.

Peter’s model has spread like wildfire-very fortunate to have met him.
And @JudithKeeney you are an inspiration to me as well.
Stay the course my beautiful friend.

You all know what we were up to!

Holistic approach to Calculus this semester-byproduct of the pandemic.
Built these open rectangular boxes by cutting squares out of the corners 1 cm to 13 cm & graphed Volume versus length of the square cut out (x).
What are the dimensions of the square for maximum volume?

With this problem we uncovered limits, derivatives and the connection to first and second differences, optimization and curve sketching.
Here is some student work.

Area = Length * Width
S “oh this makes so much sense!”

Then place equations of area form of quadratic and length/width form of a quadratic into Desmos and see they land on top of each other, then connect area form to y intercept and length/width form to x intercepts, sketch the graph, talk about symmetry , find x&y value of vertex.

All in the name of engagement. S’s are up out of their desks, moving about, writing on whiteboards, building , thinking-exactly what I value in my classroom.
The third day we build quadratics just with tiles and do a full analysis. Can bring in negative signs easily now.
