              Angles in a Quadrilateral

              Students extend their understanding of angles in a triangles to calculate missing angles in a quadrilateral.  As learning progresses they calculate unknown angles using a combination of angle properties, such as, angles about a point, on a line and in triangle.
              Differentiated Learning Objectives
              • All students should understand that a quadrilateral is made up to two triangles and therefore has a sum of 360 degrees.
              • Most students should be able to calculate an unknown angle with a quadrilateral.
              • Some students should be able to prove there are 360° within a quadrilateral by considering external angles

              Angles in Polygons

              There are two key learning points when solving problems with angles in polygons.  The first is to understand why all the exterior angles of a polygon have a sum of 360°.  The second is to understand the interior and exterior angles appear on the same straight line. Students can be told these two facts and […]

              Mathematics OFSTED Inspection – The Deep Dive

              Earlier this week, my school took part in a trial OFSTED inspection as part of getting ready for the new inspection framework in September 2019. This involved three Lead Inspectors visiting our school over the course of two days. The first day involved a ‘deep dive’ by each of the Lead Inspectors into Mathematics, English […]
