Used Formative to collect and share student responses in a vareity of ways for our 3 Act Math Play on Slope

Let's take a look at look at the properties of slope and how they relate to our school's wheelchair ramp. To do this we are going to do a Three Act Math Play. In the first act you will need to make a prediction of the slope of the wheelchair ramp on the west side of the school, in the second act you will need to figure out the information you will need to varify your prediction, and in act three will we see how close your precdiction came to what we actually caclulated. For good measure we threw in a bonus act in the end.

To get us in the mood for the play, let's watch this video.

Let's use this GeoGebra app to explore slope and how rise and run affects it.

Ok now your ready to go ... let's do this!

ACT 1 - The Prediction

Share your predictions in a method that you are most comfortable with (audio/show your work/ short answer).

What information do you need in order to solve the problem?

* This information would be added to the formative once the predictions are made. *

After going outside with our measuring tape we found the rise 0.58 m and the run to be 4.92 m.

We would need to use the formula rise over run.

ACT 3 - Conclusion

* This information would be added to the formative once the predictions and information are given. *

Here is the solution to this problem.
