Ok, ok, I'm making a pitcher of margaritas, come on over . . . 

Around here "Free" is always good!! Why is it that the powers that be think that having smart kids = having lots of money?
  Quite a few of our museums offer free (or super cheap) "homeschool kits" that you can check-out for a period of time.  They typically include a specific curriculum, manipulatives or equipment necessary to conduct a project or experiment and supporting books/information.  Some are better than others but for the price they are worth checking out.  I do believe you have to be a museum member though so there is an underlying cost.
