"This used to take me 4 minutes. I would write four rules on the board and they would copy them down.Today it took 24. But it was fun. And later I saw somebody end-behavior dancing in the hallway.This approach is better than just telling them, right?"That is, sure it's faster to just tell them, but they likely won't retain the info or enjoy it as much. Get all the cards from these two posts.

Here's a great maximizing volume activity that can be done with grade 9 students for that part of the curriculum. Of course it could be a calculus activity too but the basic principle is "what is the largest open topped box you can make from a standard piece of paper. This is actually an old post from Fawn but was just mentioned by used by Julie at I Teach Math and updated from the original 2013 post with Desmos and Google forms.

Mary at the Making Math Meaningful blog has an activity that reminds me of our own squaring activity for discovering Pythagorean Theorem in grade 8. It's one of the activities she is using to spiral through the curriculum in grade 10 applied. As she did last year, this year she is blogging about each class. If you teach grade 10 applied and are into something a bit more progressive, then check out her blog

I know it's late but the Valentine's Desmos app was a fun way to say you love someone - with math. You can still send them a Math-o-gram
