For the last few years I’ve been going in once a week to help out at my children’s school. Each week I watch the poor teacher struggle to teach concepts to children that don’t really care. Because their audience is generally not the slightest bit interested in what they are teaching, it turns out that elementary teachers are amazing at teaching! I really do enjoy listening to them teach things like math principles that will finally become relevant when they are in calculus, or geometry. So for about 15 or 20 minutes each week, before I get my turn to help out, I sit back and relearn things from the perspective of a fourth grader, but with the knowledge of an adult. And I’ll tell you, I think of the craziest things!

This week, I came up with new ways to look at fractions and folding paper. Folding in half is easy, and so is fourths, eighths, sixteenths, etc. But what happens when your teacher asks you to fold in fifths? Watch the video to see what I came up with in my weekly fourth grade adventure.
