I wrote this activity to give my students practice with classifying word problems as either linear, quadratic, or exponential. There are 45 cards to match: 15 story cards, 15 equations, and 15 verbal descriptions (linear, quadratic, exponential or neither). There is no solving to do, but it is tough task none-the-less. I watched my 8th grade algebra students work through this activity and exactly what I wanted to happen transpired, "Wait a minute... all of these have a 225. This is really hard." Yes it is challenging!
I don't think technology is needed, but you can decide that as their teacher. Answer key is included.
