I just finished putting two new student screencast playlists online from my BC & Multivariable Calculus class. Enjoy!
13.3 – The Dot Product
13.4 – The Cross Product
Here’s a particularly strong student video from 13.3:

Over the past week my BC & Multivariable Calculus class has begun their journey working through the wonderful land of three dimensional space. In order to get my students to think more deeply about the dimensions they are now operating within, I have been working Origami into my lessons. I started with hyperbolic paraboloids and now have just taught them the first few skills they will need to create their own 60-piece stars.
They now know how to make the pieces and over the next few days I will be helping them figure out how to fit them together into a closed, 60-piece star! Here’s what the whole process looks like:
One of my favorite surfaces is the hyperbolic paraboloid. So, of course, all of my students need to know how to fold one from a square sheet of paper. Last night my BC & Multi students practiced their folding skills and today in class their quiz was to fold one on their own without the instructions. They certainly impressed me with their folding skills!
Here are the instruction (PDF). Try folding one!
