Lessons in this chapter

  1. 1Measuring the BoundaryLearn how to measure the complete boundary of a shape and use it to solve everyday length problems.
  2. 2Perimeter in Paths and Changing ShapesFollow runners around tracks and see how diagonal edges and shared edges affect boundary length.
  3. 3Measuring Area with Square UnitsUse equal squares to measure enclosed regions, derive area formulas and solve covering problems.
  4. 4Same Area, Different PerimeterExplore how rearranging pieces preserves area while changing their outside boundary.
  5. 5Finding Triangle Areas by RearrangingDiscover triangle area by cutting rectangles and use triangles to measure more complicated regions.
  6. 6Area Puzzles and Floor PlansUse shared edges and missing dimensions to solve floor plans, area mazes and practical layout problems.
  7. 7Chapter Summary and PracticeConnect boundary, enclosed space and rearrangement through a complete chapter review and mixed practice.
