About This Lesson
Here is the opening activity I made for opening activity in teacing slope at my Geometry classes. #9, #10 is rivised and edited. Rather than Constant Rate of Change in Algebra class, I use Rise over Run in similar or non-similar trialges to open up sloope topic. This lesson is made with ideas of CCSS 8.EE.6 - There could be same slope in several Similalr Triangles. Students should be familar with the concept of Rise over Run then can be brought to Slope Formula (y2-y1) as Rise and (x2-x1) as Run... Comment and Suggestion is appreciagted
