Construction angles and perpendicular bisectors lesson observation

Here is a constructive lesson on constructing angles (60 degrees, 45 degrees, 30 degrees, 15 degrees) and perpendicular bisectors (of a line, at a point on a line, from a point to a line).

For the second part of the lesson, I created videos for the students to watch which demonstrates the constructions (It can be a lot to listen too and this works well).

I have taught this several times and once during an observation and it was a good solid lesson. Here you have to chance to assess learning outcomes with an assessment sheet and its fully differentiated. The worksheet is structured with steps and gives students questions to attempt.
