Ok, a while ago I made a list of my most used free worksheet links, there are of course many more webpages that I have found important in my HS - from fun interactive sites for the kids, to sites designed for different types of learners (my oldest is a visual). Here is my list of what is in my favorites list.
Interactive Sites -
Miamiopia - the kids LOVE this site and play it while I'm making dinner.
Big IQ - math, spelling & Geography. The kids play about 30 minutes each.
12 Dozen Places to Educate Your Kids
Click n' Kids (Phonics and spelling) -- ok this is not free, it is about $50/mo but it is sooo fun!
Head of the Class - this site is a little disappointing - each lesson starts with a great animation, but many (MANY) of the lessons are actually worksheets. But it is free, and great on a day I'm sick or the kids need a distraction.
Lesson Plans -
more to come!
