This worksheet is designed to replace a lecture on the slope formula. While my Geometry students technically should already know this formula from their previous year in an algebra class, very few actually know it or understand it, so I wrote this worksheet to find that happy medium.
I start out class with a 15-minute "mini-lesson," giving my students some basic examples of what today's lesson will be about. Once the mini-lesson is over, I have them get to work within their groups on this worksheet.
The worksheet does include the slope formula after the discovery portion, just to make sure that those who were absent, those who straggle, or those who need confirmation of their work can keep on track, feeling confident as they go.
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.
This worksheet is intended to be written on directly.
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.
