              Estimating Solutions by Rounding

              Students learn how to estimate solutions by rounding numbers to a significant figure.  As learning progresses students also consider approximations of square roots and using the order of operations to break calculations down.
              Differentiated Learning Objectives
              • All students should be able to estimate a solution by rounding each number to one significant figure.
              • Most students should be able to estimate a solution by rounding each number to one significant figure and the nearest square number.
              • Some students should be able to estimate solutions using a combination of rounding to the nearest significant figure, square/cube number or square root.

              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 […]
