It's easy to count three of something-- just add them up. But how do you count zero, a number that is best defined by what it's not?
Can you see it?
Can you hear it?
Can you feel it?
This important math concept is beautifully explored in a way that will inspire children to find zero everywhere--from the branches of a tree by day to the vast, starry sky by night.
