I LOVE Common Sense Media! (No, they are not paying me to say this.) They have fabulous lessons for kids and information for parents regarding anything and everything technology. You can get movie, video game, and TV reviews that let you know what is or isn't appropriate for kids. I use their online safety/digital citizenship curriculum often when I teach classroom lessons to all grades.
They have just launched a free program for families called Wide Open School that will pull the best of the best collection of online learning experiences. Because we are all on resource overload (see my last post) this is a great thing to help pull everything together and to stay organized (and sane).
