Ted! Lighten up! Just because *you* don't know a connection between the Sierpinski Triangle and Pascal's triangle doesn't mean there isn't one.
Here's a homework problem for you:
Write out a large section of Pascal's triangle. Pick a prime (say, 7). Highlight all the entries of Pascal's triangle that are divisible by 7. Find a pattern. Explain why it happens. What would you get if you used a really big section of P's triangle, say, 100 rows or more? What would happen if you used *all* of Pascal's triangle?
p.s. Pascal's triangle was known to the Chinese many centuries before.
p.p.s. Last spring I was working with a class of 6th graders who had just been studying ancient Greece in literature and social studies and art. I decided to introduce the Pythagorean theorem informally, and I thought they would be intrigued to see Phythagoras' name written in Greek. They pracitcally jumped out of their chairs with excitement: they could read it! So, yes, it does sometimes help to discuss Greek drama.
