Hi all, I have to plan the above topic to teach Y7 L5-6 for 30 minutes(interview lesson). What's the main points I should be focusing on? I know the three points of descibing any rotation( center of rotation, angle of rotation and direction of rotation). What else I should be taking account of? this is my first time teaching this topic. And is there a good activity i can do for 15 mniutes?
