There are so many interesting relationships between numerical patterns. Look at this neat relationship between the Sierpinski triangle and Pascall's triangle. If you color all the even numbers one coler and all the odd numbers another color you get a Sierpinski triangle. There's also a relationship between Fibonacci numbers and Pascall's triangle. If you add the diagonal numbers in Pascall's triangle you get the Fibonacci sequence.
Wouldn't it be wonderful if young children could learn these magical mathematical relationships in elementary school rather than learning math as a disjointed unrelated group of rules and facts. It would be much easier for them to remember their addition, multiplication and subtraction facts if they saw the relationships between them.
