Subject: Re: Decorating my classroom

I used to hang mobiles from the lights and from the ceiling.  Each mobile
had a math theme:  quadrilaterals, real number system, chapter summaries.
Sometimes they were assignments.  Sometimes they were extra credit projects.

      Real Numbers              be a lesson in balancing.  (How far from the
           |                    fulcrum should "irrational numbers" be placed
           |                    so that the mobile is balanced?)

Warning:  If your classroom has a burglar alarm that is set off by a motion
sensor, ... well, I think you can figure out why I don't do this any more.

Cheers!
