A nice pentagon problem for kids learning geometry

Fun morning with my older son today as we slowly work our way through the section in our book about polygons. We stumbled on a neat problem about pentagons. It turned out to be a great problem for the white board and also a nice problem to look at with our Zometool set.

First on the white board:

 

Next with our Zometool set:

 

I was happy to run across a problem that we could approach two seemingly different ways. Happy also to see the Zometool set used not just for special project, but also for more day to day work in learning geometry.
