A million dots on one page 

You can use lots of dots to help grasp large numbers. Here are 10^{3} x 10^{3} = 10^{6} (1,000,000 ; one million) dots.
The dots are dots. The small squares are 10^{1} x 10^{1} = 10^{2} (100) dots. The big squares are 10 x 10 of the small squares, so 10^{4} (10,000) dots. To get a million (10^{6}) we need 10^{2} of the big squares. Depending on how wide your window is, that's 10 x 10, or 5 x 20, or 4 x 25, or 3 x 33 plus 1. As below...
