Since I'm mom to a preschooler, I would like to add some preschool resources to this list. There is a website called AtoZTeacherStuff which is loaded with ideas for fun activities for young kids. Another one I like are these preschool games which my son loves playing.. he learns from them without realizing the fact that he's doing so! Then there's another site that goes by the name of First-School which helps me build up and plan my homeschooling lesson plans. Right from colors, shapes and seasons, to arts and crafts as well as other educational stuff, this one is a must-visit website.
