I use this in my Algebra 1 class to introduce slope. I start out with a story about my "first skiing experience." I explain how when I was on the ski lift it was fun and I had a "positive experience." Then I was going way too fast down the hill and my feelings were very negative. Then I got to the bottom and I was cruising and I had 0 feelings. Then there was a small cliff at the end that I did not notice and my feelings were undefined as I was falling.
My students absolutely love this story and the drawing that goes with it. Students then get to create their own skiiing experience using the graphs.
There are also some real life application problems included that I like to go over at the end.
This visual helps students remember the different types of slopes. I also refer back to their skiing stories whenever we talk about slope.
This is given as a smart notebook file that I usually print off as 1 page and use it as a hand out. You can also just display it on the smart board and have students draw their own skiing experience in their notebooks.
