Here is a website with a compilation of short movie clips on math and physics that you can freely download. http://www.math.harvard.edu/~knill/mathmovies/index.html I use the Shrek clip as the introduction to inverses and contrapositives in Geometry.(This one was also on YouTube.) The PowerPoint I used is in the Box widget.

Drill, drill, drill!

Finished! I have 27 pages of drills on 1) multiplying, 2) number sense-ing (working in groups of 10), and 3) adding/subtracting integers. They have been combined into 2 PDFs in the Box widget, now moved to the left of the page. These drills are to be used for the Timed Folders and all of them [...]

Several years ago at my very first math conference, I accidentally walked in to a session for elementary teachers (before learning that they were categorized by grade levels for you). It was on Singaporean Math, where I finally understood what “number sense” meant. Out of all the epiphanies and eye-openers that I was absolutely amazed [...]
Better than the “Mad Minute” Drills

It doesn’t surprise me at this point, but I have many 9th graders who can’t multiply… by 2, let alone by 8. count 12-2 or 8+2 on their fingers. Hell, I’ve even seen 3+2 need fingers. forget how to do 4-3 when taught the existence of a 3-4. So what do we do as high [...]
As I am catching up on reading Steven Strogatz‘ brilliant articles on math, this one in particular is really making me want to teach elementary school math again! I dream of being Deborah Ball and creating sassy lil kids who debate why odd numbers are odd. I also dream of being Jaime Escalante and randomly [...]
SIX days of 95 minute block periods spent on HOW TO USE A RULER and all but ONE failed the 5 question test. Not only can they not find the fractional part of an inch, they are still reading 3 inches as 4 if I don’t start the ruler from 0!! **help**
Pre-Algebra Confession: While all this debate is brewing about Ikea changing their font, I snuck in and took a stack of their paper rulers. Actually, I was just the driver who kept the engine running while a couple of my kids who graduated last year went in to do the job. =P Hehe. Well, this [...]
