Not much to report - the class was spent allowing students to work on U2 WS2 which dealt with using rulers and protractors correctly.
I know a million different ways to show/explain this skill, but I have to find a consistent way to ensure that students are internalizing what we're doing. Generally, students think this is so basic that it's a waste of class time, but the truth is always revealed come quiz time. That might be an investigation to itself - how to work with students who consistently think they know material that they very obviously do not?
I was a little optimistic that students seemed to connect our work with "angles as portions of a circle" to why protractors are half circles. A little disheartening to see so many use the ruler part of a protractor to measure an angle though.
