              Enlarging Shapes to a Scale Factor

              The start of the lesson is used to review similarity within triangles.  The development phase goes onto extend this by introducing enlarging shapes to a scale factor using a positive integer scale factor and using a centre of enlargement.
              Differentiated Learning Objectives
              • All students should be able to enlarge an object to a positive integer scale factor.
              • Most students should be able to enlarge an object to a scale factor and centre.
              • Some students should be able to perform and describe an enlargement using a positive scale factor.

              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 […]
