              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

              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 […]
