A couple of free things.

One is for people with younger kids just learning to read and is only free until the end of January.  It's the Funnix reading program, which is usually over 200 dollars, free for download for a few more days.  Here's the link. 

Next is always free and is for high schoolers and middle schoolers.  It is the Khan Academy and has all kinds of videos to teach such things as algebraic functions.  I haven't watched any videos because I am home today and therefore have the world's slowest internet service.  Anyway, here it is Khan Academy.

We are going to watch a DVD we got from the library called Doktor Kaboom.  Sounds fun.

**Updated to add, Doktor Kaboom is fun.  We had done a lot of the experiments previously in our homeschool, but had never made an air cannon, so when the DVD was done, we went into the kitchen to make air cannons and blow smoke rings.  It was very cool.
