I love freebie newsletters. I'm building archives in my documents folders. Just save the free files in your documents, creating folders for each subject as you go along. Then when you're putting together a unit on the American West, just check and see if you have anything in you Social Studies folder. The free stuff may even inspire a whole new unit idea.
So here are some of my favorites. I've probably shared them before, but I'll put them all here together this time.
Dover Publications - these samples come to your inbox once a week. Fine art coloring pages, clip art, presidential paper dolls, preschool activities, origami - it'll make you jump up and down and clap. :^)
Currclick- note the "free stuff" link on the left side of the front page. You will get a weekly e-mail with a free product download each week. This is a great site for buying lapbooks and copywork files that you can instantly download. I've gotten great sets of illustrated Scripture copywork for $.50 - $1.50 here.
Learning Page - sign up for a free membership that gives you "no strings attached" access to the worksheets. You'll also receive an e-mail to notify you of new sets of worksheets. This used to be once a month, but the site's been undergoing some changes recently. However it remains a treasure trove for the 3rd grade and under set. Mine it!
Time for Kids - this is Time magazine's student publications newsletter. It will link you to the new worksheets for each month. Most can be done without the publication, and they are usually very relevant. Recent newsletters have contained New Year's resolution and Olympic worksheets, for example. There are also lots of archived articles and worksheets. Find the newsletter link at the bottom right corner of the page.
The Homeschool Freebie of the Day - Add this one to your bloglines! Each day you get a new download. Free products offered by other, often independent, publishers. Books that are public domain in pdf format. Radio shows from the 30s-50s on mp3. You're gonna love it! Right now they're downloading The Big Handbook of Nature Study by Anna Botsford Comstock, in several parts. Don't miss out. Add this one to your bloglines, or sign up for their mailing list.
