Made 4 Math: Distance Formula Project
Earlier in the year I talked about teaching slope with the method somebody later tagged "stack and subtract". This worked so well for me that I decided to use the method in my geometry class for the distance formula. We did a lot of practice and I decided I wanted to a do a little project instead of a standard test to assess this concept.
We did a mock version of finding the perimeter of a figure on a coordinate plane by using a simple version of @pamjwilson's idea mentioned on her blog here.
I even created an Excel file to check their work- just plug in the ordered pairs and it will calculate the distance of each segment and the perimeter of the polygon. (To know what I'm talking about you really should go read Pam's post!)
