              3D Trigonometry

              To solve problems involving trigonometry in 3D shapes students are taught to identify 2D right-angled triangles and apply the Sine, Cosine and Tangent ratios.  As learning progresses they consider square based pyramids in addition to cubes and cuboids.
              Differentiated Learning Objectives
              • All students should be able to calculate a length in a 3D shape using 2D representations of right angled triangles
              • Most students should be able to calculate an angle in a 3D shape using 2D representations of right angled triangles.
              • Some students should be able to calculate a combination of length and angle in a 3D shape using 2D representations of right angled triangles

              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 […]
