Patterns in the binomial expansion, Pascal

Realizing that (X+Y)n can be expanded with the help of Pascal's Triangle offers some pretty and interesting math play.  We love to bring a little fun and beauty into our math classes and the end results are neat!  Here is the first of 3 activities using Pascal's coloring. 

This Binomial expansion activity could be used alone or coupled with our introductory Pascal activity (see activities)

If you wish to focus only on the coloring and Pascal's Triangle, you might use this Hexagonal grid paper.
