              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.
