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.
