DBoyz Page Is Just
A Click Away

 Just let me in, NOW.

These two little boys show you an amazing array of math using base ten blocks on the following page. People always ask how to show negative polynomial expressions using the blocks. There's vid of that here. We play with Pascals Triangle, use Legos for teaching fractions, fool with Polar Coordinates and more, price of entry is a password.

The videos are in no particular order but just about all of them are unlisted which means you won't be able to find them anywhere else.

Here is a sneak peak at what you are going to see. <Hit full screen for best results.>
