              Gradient of Perpendicular Lines

              The start of the lesson is used to recap calculating the equation of straight line graphs.  The development phase teaches students how to calculate the gradient of perpendicular functions.  As learning progress they are challenged to derive the equation of perpendicular graphs.
              Differentiated Learning Objectives
              • All students should be able to calculate the gradient of perpendicular lines.
              • Most students should be able to calculate the equation of a perpendicular line.
              • Some students should be able to calculate the equation of lines in the form ax + by + c = 0.

              Angles in Polygons

              October 16, 2019

              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

              July 6, 2019

              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 […]
