we do have a stack in each of our gymnasiums. after "assigning" one to a student we just keep it on file in the PE office until the next time we need it!
Students only get credit for what they have finished, each time they miss they have an assignment to finish. If they get it done they get credit for completing whatever they finished.
Although we require all students to change for physical education, unfortunately that it not always the case. If and when a student does not change, they are required to fill out a non-participation form for that day. This form has 10 questions for students to answer while observing his/her physical education class. Students are also required to bring this completed form home for a parent/guardian to sign and return to class the following day. We ask students to have a parent/guardian sign it so they are aware that their child did not participate in class that day.
