Copy and paste the quiz below into a Google Doc entitled "QUIZ on Feedback and Diabetes Basics." Highlight all of the text you just pasted in and strip the formatting (teacher will demonstrate this).
Take the following quiz in your selected group. Answer each question individually and then discuss your answer with your group. Do not move on to the next question until you reach a consensus.
To form your final answer in your Google Doc, copy and paste your selected answer option(s) together with a copy of the original question so as to form a complete and true statement. The answer phrase you pasted in should appear in bold and underlined (see example below).
When your team is finished, make sure your team lead shares his/her quiz with me for scoring.
