Can be used at any point during a lesson to check for understanding. File is a PDF, created as a Publisher Document. If you are unable to edit PDFs, convert it to a word .doc and you should have no problems. If you would like it customized in some way, please let me know and I'll make changes for you (reasonable ones of course :)).
Also, I'm offering this for free, but I'd like to hear how you use it or if you have success with it or suggestions for revisions!
