My first grader wanted to learn more about money today.  I thought quickly on how to simplify a monetary system gone haywire.

My oldest is in first grade and the youngest is 3.  I'm always looking out for opportunities to teach concepts, content, or skills to my daughters.  While the oldest is in school, my youngest and I go on nature walks.  Sometimes our nature walks acquire a collection of leaves and twigs and dirt that we place under a microscope to make observations.
