Missing angles 3 lessons

These are three lessons that I did with my year 6 class.
Lesson 1: looks at finding the missing angle on a straight line and around a whole turn. On the PowerPoint, there is a printable worksheet which is differentiated for LA, MA and HA mathematicians. The answers are on the next slide. You could use these to get the class to self-mark and save your valuable teacher time!

Lesson 2: revises learning from day before then moves onto finding the missing angles in triangles. My class had a basic knowledge of the features of an equilateral and isosceles prior to this but the lesson offers a brief opportunity to revise the features. On the PowerPoint, there is a printable worksheet which is differentiated for LA, MA and HA mathematicians. The answers are on the next slide.

Lesson 3: this is a reasoning lesson during which I sent out my LAs to work with my TA on MA work from day before. The lesson looks at opposite angles and finding missing angles in diagrams that contain triangles. There is a Word document worksheet for MAs and HAs.
