              Simplifying Ratios

              The start of the lesson is used to review matching simple proportions with their corresponding diagrams.  The development phase builds on this by introducing ratios using diagrams.  As learning progresses students begin to simplify a ratio by calculating the highest common factor.  The plenary consolidates the learning by matching up equivalent ratios to find the odd one out.
              Differentiated Learning Objectives
              • All students should be able to simplify a ratio using common factors.
              • Most students should be able to fully simplify a ratio using the highest common factor.
              • Some students should be able to calculate equivalent ratios involving multiple different units.

              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 […]
