Use your powers of estimation to figure out the answer! It's simple: start with a small amount and work your way out.

Have you ever tried to estimate the number of jellybeans in a jar? If so, you may have looked at the size of a single jellybean and compared it to the size of the jar. Then, based on size, you may have tried to imagine how many jellybeans could fit in that jar.

Or maybe you’ve tried to estimate how many steps it takes to walk to school. You may not have counted every step. Instead, you may have thought about how many steps it takes you to walk one block; then multiplied that number by the number of blocks you have to walk to get to school.

You get the idea. You can use this same technique to estimate even larger numbers!
