              Substituting Numbers into Expressions

              Students learn about substituting numbers into expressions.  Using the order of operations they are taught how to break down and evaluate an expression.At the start of the lesson students use the correct notation to complete an algebra product grid.  In the main phase they learn how to substitute known values into an expression using BODMAS and evaluate the result. The plenary challenges students to sort a range of expressions through substitution.
              Differentiated Learning Objectives
              • All students should be able to substitute known values into algebraic expressions in the form x ± a.
              • Most students should be able to substitute known values into algebraic expressions using the order of operations.
              • Some students should be able to substitute known values into algebraic expressions involving powers.

              Literacy in Mathematics – Creating Problem Solvers

              October 28, 2019

              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

              October 16, 2019

              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 […]
