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!)

I've been teaching 20 years...its been refreshing to read your blog and be inspired by your enthusiasm for teaching. It's obvious you love it and your students. I hate to see you say "you missed the mark." Despite the rhetoric,we are not magicians. We study, prepare, and try to improve. At some point our students must do, at least, some of the same. Take care of your beautiful self. You have a lot to offer.

ReplyDeleteThanks for the encouraging words. I'm feeling pretty bored right now with my teaching but I am definitely not a magician.

DeleteI like this project. Could you have maybe asked the students to "critique" or evaluate the project after it was all done? Maybe by getting their feedback on what they felt was on point or missing, it will help you to improve the project for next time. This can even be an anonymous survey just to get feedback.

ReplyDeleteI usually do that on projects but I forgot about it this time. I have realized that I had the highest amount of students who were willing to make corrections to this project for more points as compared to other tests. And I noticed when we did the Pythagorean Theorem on a bell ringer that I had a ton more participation and accuracy so I guess I did get some good byproducts.
