One of my other bargain finds shopping with mom are school books. One of my favorite thrift stores had several Abeka books and McGraw Hill's Complete Book workbooks.
I found a few of the Abeka readers and while we are not using Abeka, they are great phonics readers and work with our system well enough. I also found a few non curriculum easy to read books that I can use as readers. These were sold for .25! Another .25 buy was an elementary level health worktext from Abeka. I don't have any materials on health for my youngest so this should help add content when we have a unit on that.
I bought the Complete Book of Time and Money for $1 with only a few marked on pages. I use various workbooks as worksheets and activities to support what I am teaching our youngest. I flip through our collection to determine which will be used each day. I have found this to be a frugal alternative to using texts and I can follow my own list of topics.
Have you found any good deals lately?
