Primary Power

One of my favorite parts of teaching a class is asking the question.."How many colors are there in the whole world?"  I wait while students make their guesses.  Sometimes they research first by checking out their crayon box for a number.  Even when they hear the answer, some will say, "Oh, you mean the primary colors.", never realizing that the primary colors ARE all the colors in the whole world.  It astounds me how many adults do not know the answer to this question, and even doubt the answer as well.  This piece is an exercise is playing with "all the colors in the whole world", the primary colors.
