I recently created a "store" on teacherspayteachers.com! If you are looking for printable certificates for PE class, please check out my store at http://www.teacherspayteachers.com/Store/Carly3.
I offer a FREE printable certificate for the MILE RUN. It prints four per page. I print them on bright colored paper and the kids love them! I have certificates for fitness testing for each event ($1 each), or the better deal is to buy the "SET" of fitness certificates for $5. I also have SKILLS certificates and GOOD BEHAVIOR certificates. :-)
