              Trial and Improvement

              At the start of the lesson students set up an equation involving the area of rectangle which is solved using a method of trial and improvement.  The development phase goes on to consider quadratic and cubic equations using a table.  The plenary involves modelling the length needed to create a volume from an open box.
              Differentiated Learning Objectives
              • All students should be able to solve a quadratic equation in the form x2+ab=c using trial and improvement.
              • Most students should be able to solve a quadratic and cubic equation using trial and improvement.
              • Some students should be able to solve any none linear equation using trial and improvements as well as derive the equation using known facts.

              Literacy in Mathematics – Creating Problem Solvers

              October 28, 2019

              Last year my school had a OFSTED trial inspection. Whilst the maths team recieved favourable feedback the inspectors noted a need for a focus on whole school literacy. Because of this I was asked to demonstrate how we develop student’s literacy in mathematics. Literacy in Mathematics By developing student’s literacy in mathematics we aim to […]

              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 […]
