This is a collection of 20 problems that I use as problems of the day. These problems review topics that are traditionally taught in Precalculus. (solving equations, writing equations of lines, evaluating logarithmic expressions, factoring, solving trig equations etc.) At the end of the set, there are 2 limit problems.
You or the students can 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.
I have also included an answer key and a record sheet for the students.
If you like this set of problems, be on the look out for further collections to help students continue their review for the AP Exam.
