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!
