I have been looking for ideas to do themes with my daughter when we start homeschooling this fall. I went to a local teacher supply/home school store today and found the coolest book put out by 'The Mailbox' company. It has day -by - day plans and over 800 activities. This book will be PERFECT for what we need it for. Here's a link to check it out: http://www.theeducationcenter.com/cgi-bin/tec/productDetail.jsp?OID=536936985 I think I'm going to like this company!
When I taught preschool I used to subscribe to the Mailbox Magazine and loved it. I still have the ones I got back then and have pulled them out occasionally for my kids. I also have a couple books by the company from long ago. They have some fun ideas especially for crafts. Alot of their stuff is geared towards classrooms, but you can adapt alot.
