Exponential functions turned out to be my students' favorite functions. I think it was because the pattern was so easy to figure out and it applied to Science (they really liked Science.) They were disappointed when we moved onto linear functions. Go figure!
This first picture is our example of exponential growth - Blooming Bacteria. I drew the graph on the whiteboard so I have another transfer issue :(
This next picture is of exponential decay - Indestructible Isotopes. Again, missing graph since I drew it on the whiteboard.
By this point, the students are beginning to like the four corner foldable but this is also where our units ends. We didn't work on just the one example per function. We actually had other practice problems but did not use the four corner model. I'm thinking this might be a part of my inconsistency. In fact, I know it is. Here I am getting kids used to a way to represent and I only did it once per function instead of having them do it every time. Note to self: if you start it and it works, keep going.
