The best thing was after the whole thing happened, Brennan had to tell them that they actually needed them to be in their seats to fix it š

Theyāve said theyāre putting it on Dropout for sure! So youāll be able to see how incredible it was :)

So there were technical issues that meant they needed to wait for some lighting changes, and Lou and Murph just decided to fill time by going full WWE.

I actually think after looking at it you're 2/3 to get the valuable goat so you shouldn't switch!

I learned regex in Python and Iām obsessed!

This is the binomial theorem! A really nice starter example for branching into some combinatorics questions (and thinking about why combinations and polynomial expansions are related is a great tool for students to understand both topics on a deeper level.

Canāt highlight enough the āmath that depends on what youāre teaching themā. A deep understanding of āwhyā weāre learning a specific topic, notation, method of visualization/communication, etc can help motivate mastery more than anything else.

Iāve used this as a parents day activity, where the kids do the angle chasing and try to figure out what each of the sides is. Itās been wildly successful, they treat it like a puzzle and if they have strong right triangle trig knowledge theyāre perfectly capable of filling in the diagram.

This perspective helps you thinking about why the probabilities are distributed the way they are.
The other thing to do to try to understand the dynamics is to imagine a world in which you have 10 doors, or 100 doors.

Imagine a world where you are inside one of the doors and a hungry ogre is picking. They pick one of the other doors. Do you want them to switch? You of course do not.
This happens 2/3 of the time.
If they pick your door, you desperately want them to switch.
This happens 1/3 of the time.

I love using the vending machine model! āIf you hit the button for a coke and you could either get a coke or a sprite randomly, would that be a good machine?ā

Thatās definitely where Iām at! Also a lot of planned variation in terms of input variable and composed functions to get students conditioned to understanding how it works.
A lot of āf is a rule that weāve defined and applied to an input āxāā also. I wish I had a magic wand!

I had a student print a cool visualization of how the gradient interacts with tangent planes that I use all of the time. Itās a cylinder that fits into a trapezoidal prism and shows how the partial derivative vectors and the gradient vectors can be visualized. Iāll snap a pic when Iām in my office.

Thereās a couple of classrooms with this going on and it infuriates me. I donāt have a good sense of time, I need the clock to let me know where Iām at!

My teaching partner printed these out and sealed them with a minions yellow sealing wax and the letter G to add to the drama of getting this request. It was a huge hit with students! (Credit to Gavin LaRose for the prompt I adapted.) 2/2

Ooh, thereās some good marketing psychology stuff in that question also. How does presentation of pricing affect consumer choice and such.
