Properties of Numbers 

Steinfelds, Leon King High School

Objectives: To contrast the "mean" behavior of 0, 1, 2 and regular numbers. Numbers will be likened to students. Apparatus Needed: Memory chalk board, chalk. Recommended Strategy: Numbers 0, 1 and 2 will be regarded as "dissident" students. 0 will act as "murderer" in multiplication, but will not even touch numbers when addition or subtraction is required. To divide by 0 creates "mission impossible". 1 does not like division and multiplication. It is invisible as a coefficient or exponent (like Dracula). 2 hides only once in radical (square root). Zero is the only lonely number. The others walk in pairs on a number line as twins. Some numbers, like square root of 2, 5, 7..., cannot be written even in one hundred years, but one knows their location on the number line.
