              Trial and Improvement

              At the start of the lesson students set up an equation involving the area of rectangle which is solved using a method of trial and improvement.  The development phase goes on to consider quadratic and cubic equations using a table.  The plenary involves modelling the length needed to create a volume from an open box.
              Differentiated Learning Objectives
              • All students should be able to solve a quadratic equation in the form x2+ab=c using trial and improvement.
              • Most students should be able to solve a quadratic and cubic equation using trial and improvement.
              • Some students should be able to solve any none linear equation using trial and improvements as well as derive the equation using known facts.
