Description: 
Pascal's triangle is a triangular arrangement of numbers corresonding to the probabilities involved in flipping coins, or the number of ways to choose n objects from a group of m indistinguishable objects. It is constructed in such a way that every number in the interior of the triangle is the sum of the two numbers directly above it. This virtual manipulative allows you to view a number of patterns as well as create your own.

Comment:  Not bad at all; explains the major patterns in the triangle. Unfortunately these explanations are not on the main page, so it takes some looking.
