Area of Irregular Shapes

Students learn how to find the area of irregular shapes by grouping.  As learning progresses they are challenged to consider the range of accuracy for their solutions and more complex irregular areas.  An accompanying worksheet that matches the interactive whiteboard presentation is included to aid pace.
Differentiated Learning Objectives
  • All students should be able to measure an irregular area involving non rectilinear polygons.
  • Most students should be able to measure an irregular area of shapes with curved edges.
  • Some students should be able to measure a irregular areas of compound shapes.
