This excellent lesson is part of a larger unit: "Topic 2 Graphing 2-variable linear equations." These activities can be done over two - three lesson periods and are intended to help the teacher successfully teach and explain slope. The examples that are given follow a logical order to help students develop a clear understanding of the concept of slope as well as how to apply the equations to slope. There are many suggested activities that then take students to the next level of applying this understanding. Overall, this is a very well-designed lesson. ……………………………………………..………………………….…….…………….………………………………………..
The author warns that this lesson might take more than one day. It seems extremely likely that this is true. The concept of clope is crucial to many areas of mathematics and the author gives this topic its due.
