I have some advice for all of you teachers and home schoolers out there: Read the Teachers Pay Teachers.com newsletter!!
Many of the products listed on TpT are free. You can see my free items listed in the top left of my blog. The weekly newsletter features 10 free items each week. The products vary by grade level and subject area, but there is probably a free item that is perfect for what you are teaching.
If you like your free download, take a minute to become a follower of that seller. You can click the button "follow me" on the sellers page at TpT. As a follower, you will receive an email notification each time the seller posts a new product. But don't worry, you can turn off the email feature if you like.
