This is a presentation using the angle family; Mr Obtuse, Mrs. Right, Baby Acute and Reflex Rex! It is a fun way to help students remember the different types of angles. The last slide contains a quick review of what they learned. The worksheet contains 6 different angles. The children must first name the angles. Then, estimate their size and finally measure them using a protractor. I would recommend using these resources with Year 4 or Year 5.
