Each worksheet will have 10 questions (each worth 1 point). The worksheets are designed to help you understand material. The worksheets are downloadable from the Assignment tool within Sakai as a Microsoft Word (or OpenOffice) and also as a pdf file. You can write on the worksheets and upload your answers or (similar to homework submissions) take a digital picture of your handwritten assignment with a camera or smart phone. All worksheet answers must be submitted within Sakai. Worksheets with answers only will be given a zero. You must show the work for credit. The due dates for the worksheets are one week before the due date for homework assignments, so that you can get feedback on problems before submitting your homework and doing your quizzes. DO NOT SUBMIT ASSIGNMENTS VIA EMAILS OR FAXES! I will not accept them! Do not ask to submit late worksheets.

- After reading the chapter on identification numbers, do you see any application in the health care system? Should health care make greater use of check digits? Use the facts in the book about check digits. Should we have a Universal Health Identification Number (UHID) for each person? Congress seemed to think so. That requirement was part of the Health Insurance Portability and Accountability Act of 1996 (HIPAA). The concept is quite controversial. What do you think?
