Homeschool Share is a website I use frequently to find unit studies and lapbook resources. The best part is that the resources on their site are FREE! (I love freebies!)
Homeschool Share is having their 2009 Blast. Check out the rules HERE to submit items in categories from Workboxes, to animal studies, lapbooks, all things preschool, the Skeleton Closet, and more! Homeschool Share is a huge site full of free resources and this is one way they add material to their site - by the efforts of creative homeschool moms who share their gifts. Of course there are also prizes as an added incentive!
