Lego Engineering

This site has lesson plans and curriculum materials to use with the Lego Robotics systems.  These are expensive kits, but are great for hands on learning.  (You might consider them as a Christmas or birthday gift if you can manage the cost.  Or get together a co-op and split the cost among a few families.)  The materials on the website are free.
