School is almost out, and that means I'm eagerly in search of resources to keep my kids' brains fresh and stimulated.  And also to keep them from destroying my house.

Of course, these days nearly every product marketed for children offers a site full of games.   Some of the especially impressive ones include:

Hot Wheels
Lego
My Little Pony
Playmobil
Thomas the Train
Pepperidge Farm Goldfish
Noggin

With the gracious help of the web-savvy moms at my own blog, I've been compiling a really fun list of kid-friendly sites.  There's something for nearly every age here!  Here they are, in positively no particular order:
