I use this worksheet with my IB/ Precalculus students to replace a lecture: I'd rather write a worksheet to "hold their hands" through the steps of finding the slope of a secant line, than to do the entire process as a lecture and then find out a day or two later what didn't make sense to my students.
I use this activity within cooperative groups, and I circulate to make sure they are getting the purpose of the questions.
The file includes spiral review problems.
For this worksheet, I expect students to show their work on a separate sheet of paper.
Please download the pdf preview file first, so you can see exactly what's included; the product file is a word document, which you may personalize for your students.
