              Using Parabolas to Solve Quadratic Equations

              Students learn how to find the solutions to a quadratic equation using graphs.  Learning progresses from solving a quadratic when the parabola is drawn to plotting their own graph and identifying the number of solutions the equation has.
              Differentiated Learning Objectives
              • All students should be able to plot solve a quadratic equation in the form y = x2 + a graphically.
              • Most students should be able to solve a quadratic equation graphical method.
              • Some students should be able to use graphical methods to explain why some quadratics cannot be solved.

              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 […]

              Getting Ready for a New School Year

              When getting ready for a new school year I have a list of priorities to work through. Knowing my team have all the information and resources they need to teach their students gives me confidence we will start the term in the best possible way.  Mathematics Teaching and Learning Folder All teachers receive a folder […]

              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 […]
