Patterns in Pascal's triangle (free download)
I have created a two-page worksheet that I'm offering here as a free download: Patterns in Pascal's Triangle . It is intended for about 4th grade level, so it doesn't go through all possible patterns found in Pascal's triangle, but just some simple ones: the sums of the rows, counting numbers in a diagonal, and triangular numbers. And of course the triangle itself! And in this link you can read about MANY more patterns in Pascal's Triangle -- such as magic 11's, square numbers, Fibonacci's sequence, and the "hockey stick pattern." Enjoy!
