Safe Wheelchair Ramps (inquiry based learning)

Our inquiry based learning group has now planned a lesson on safe wheelchair ramps and we have observed the lesson in two teacher’s classes.
Here is the lesson: https://docs.google.com/a/ocdsb.ca/document/d/1cmBfTzcf53tUxuxGb-Rbl5HBnSUqw7HIlKhBhObtcfc/edit#

In both classes the level of engagement amongst the students has been significant. Both teachers were quite happy with the engagement.
Lots of questioning and inquiry in both classes with students showing mathematical thinking. Definitely some misconceptions in the classes but....I think the students resolved these.

Debriefing the lesson the second time seemed to have a little more structure to it and seemed to be a little more focused. I think we as a group will get better at this process as the semester moves forward. I am so lucky to be able to work with this group of educators who are focused, committed and taking risks. Kudos to all. Looking forward to hosting the next lesson study in early April.
