This article shares an idea that I used on Fridays when I was teaching high school mathematics at an all-girls Catholic high school. I liked to give some form of assessment on Fridays because the students were always very “antsy” and talkative, and assessment was a good way to wrap up the work of the week. However, the lesson did not always lend itself to a written assessment on that day. For Fridays when I was not giving a written assessment, I devised my oral quiz. I usually used this activity once or twice during each marking period. I also plan to use this idea in the college-level developmental mathematics classes that I currently teach.
