Area of Composite Shapes

Students learn how to find the area of composite shapes.  Learning progresses from counting the squares inside the shape to breaking them down into individual rectangles.  More able students are challenged to consider overlapping areas.At the start of the lesson students recap finding the area of rectangles and squares.  In the main part they learn how to find the area of composite shapes by breaking them down into their rectangular components.  In the plenary students are challenged to investigate possible perimeters for a fixed perimeter.
Differentiated Learning Objectives
  • All students should be able to count the squares inside a compound rectilinear shape.
  • Most students should be able to calculate the area of a compound shape.
  • Some students should be able to find the area of a compound shape with algebraic lengths

How to Solve Quadratics by Factorising

The method of how to solve quadratics by factorising is now part of the foundational knowledge students aiming for higher exam grades are expected to have.   Here is an example of such a question. Solve x2 + 7x – 18 = 0 In my experience of teaching and marking exam papers students often struggle with […]
