Found this fabulous idea today. I already use transparencies in our Math U See workbook (the pages aren't removable), but this is a great way to reuse those tear out workbook pages, plus keep it fresh by offering just a few at a time. I already had some of the folders (got them at OfficeMax for 1 cent each a few weeks ago!), so now I have some of these made up for handwriting practice. Whoo hoo!
