Fourth and Fifth Graders Do Math Indoors and Out!

This photograph shows fourth and fifth graders working on the following theoretical problem: Assume that scientists are going to try to count all ~100 billion neurons in the human brain, at a rate of 1 cell per second (it would take longer than a second but let’s just use one second as an estimate). How many cells would they count in an hour, day, week, and year?

In the picture below, you can see students measuring various parts of our play area including tree stump heights, bench lengths, and much more.
