This is a collection of 20 problems that I use as problems of the day. All 20 of these problems review topics that are traditionally taught in the first and second semester of Calculus AB. (Limits, Derivatives, and Applications of Derivatives, Integrals, and Applications of Integrals)
I project these problems at the beginning of class to give the students a quick look at a review problem. It seems to help get their minds on math as soon as they enter the room.
Scan the QR Code on each page to get the answer to that question. Most QR Codes lead to a simple numerical or word answer, but several of them lead to a website that will show the answer in proper mathematical notation.
If you do not wish to use the QR Codes, the answers are included separately.
I have also included a record sheet for the students.
