              Introducing Angles in a Quadrilateral

              Students are introduced to angles in a quadrilateral by investigating how they are formed from two triangles.  More able students learn how to prove this property using algebra.
              Differentiated Learning Objectives
              • All students should be able to calculate a missing angle in a scalene quadrilateral.
              • Most students should be able to calculate missing angles using the unique properties of each quadrilateral.
              • Some students should be able to prove the sum of the angles in a quadrilateral.

              Literacy in Mathematics – Creating Problem Solvers

              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

              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 […]
