Zero Is the Leaves on the Tree

t’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.
