              Finding the Highest Common Factor

              Students learn about finding the highest common factor of numbers and terms.  More able student learn how to find the highest common factor of expressions.At the start of the lesson students recap finding factors of numbers and simple terms.  In the main phase they find the factors of numbers and terms to select the highest factor that is common to all values.  At the end of the lesson they are challenged to solve a real life problem by finding the highest common factor of two numbers.
              Differentiated Learning Objectives
              • All students should be able to calculate the highest common factor of two integers when given their factors.
              • Most students should be able to calculate the highest common factor of two or more integers.
              • Some students should be able to calculate the highest common factor of two or more terms.

              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 […]
