Lattice Multiplication. I had watched it the other day and loved several things about it:
- different colors on a simple black background
- it was only 7 1/2 minutes in length-- perfect!
- Sal Khan is a clear speaker with a laid-back, but engaging, voice
I hooked up my laptop to our projector and had kids in the meeting area with a white board, dry erase markers, and the new erasers I made (um, I cut out small squares of black fleece, but the kids love it and they do the job, so it's perfect!).
We started Lattice Multiplication last week for two days, but only got as far as 3 digit times one digit, so the concept of extra rows was new. I definitely paused a lot as we went through and had the kids copy the problem and how to solve onto their own whiteboards. By the last problem, I had the kids work on it for a minute or two, then compare their work to Khan's.
We also made a prediction about what place value our product would be-- many thought hundred thousands and a few thought millions, so it was exciting for them to see it was such a huge number.

Have fun looking around the website-- there is a whole section on Art History that looks fascinating!
