Ideas for Teachers
Use this activitiy to quickly check that all pupils in the class can work with angles in a quadrilateral, using Show Me boards. Get them to generate their own quadrilaterals in their books, giving three angles, and then check their quadrilaterals using the activity.
An extension task for this activity could be getting the pupils to make different quadrilaterals using the angles. What angles do they need to know to make each quadrilateral? Which quadrilaterals can they make with no information about lengths?
