I like to share things that other people have shared with me that I find interesting, so here are some things that I have picked up online and at a recent homeschool meeting that I attended.
#1 The First Year of Homeschooling Your Child by Linda Dobson ISBN#0-7615-2788-5
This is a great book for anyone that is new to homeschooling or considering homeschooling. I'm just reading a chapter or two a day and really letting it sink in. It's very popular, so there is a good chance your library or used book store has it. If not, try looking on....
#2 PaperbackSwap.com
I have been a member of this site for 5 or 6 years. I will not admit to how many books I have mailed out and received, but if you are a homeschooler or just someone that loves to read, you should check it out. Basically, you list books that you are willing to permanently trade. You pay the media mail shipping when someone requests one of your books, and then you get a credit to order any book from the website. If a book you want is not available, you can put it on your WishList. The site holds your place in line and lets you know when it's your turn.
#3 EdHelper.com
I learned about this at the homeschool meeting. They have all sorts of printables on this site. You can stick to the free stuff, pay $20 a year for the basics, or pay $40 a year for access to all of it. Some parents told me that they don't buy workbooks...they just pay the $40, buy ink, and paper, and use this site.
#4 Pizza Hut's BookIt! Program for Homeschoolers
Thank you, Pizza Hut! Free personal pans for kids who meet their reading goals, and it's easy to sign up too. http://www.bookitprogram.com/enrollment/homeschool.asp
#5 Scholastic Books
If you want to order books through Scholastic, you can register as a teacher of a home school here: http://clubs.scholastic.com/clubs/requestcatalog.shtml. Click on Get Started under New to Clubs. Fill everything out, and you will be told that your school will need to be verified. Within a few business days, you should receive an e-mail requesting more information about your home school. It's a couple of hoops to jump through to get started, but if you like to order books through the school fliers, it's worth it.
