Area of Compound Shapes

Students use a tool to 'cut' compound shapes into triangles and rectangles and then select the appropriate formula to calculate the area of each piece and, finally, the area of the total compound shape.

Students are encouraged to be efficient in their 'cutting' so that their compound shape is cut into a small number of pieces. Shapes presented range in size and complexity.

'Compound shapes' is an aggregated learning object combining the three other learning objects in a sequence.
