Presentation Transcript

  1. Area and Perimeter of Composite polygonal shapes http://hench-maths.wikispaces.com

  2. Learning Sequence • Conversion of units • Perimeter of Polygons • Area of Polygons (individual shapes) Parallelograms, Triangles, Trapezium • Perimeter and area of compound shapes with polygons

  3. Preliminary Activities • Digilearn: Area of Compound shapes Basic Complete at least 2 of these shapes • Digilearn: Area of Triangles Complete at least one question at each level • NVLM: Tangrams Do one tangram use hints if needed • Digilearn: Compound shapes advanced Do at least two from the small category

  4. After completing online activities • Review the formulas for Perimeter and Area of polygons on the next slide • View the animated worked example on the following slides • Complete the written assessment task and hand it in for assessment

  5. Formulas for Quadrilaterals

  6. Example 6cm 8cm 8cm 12cm

  7. 6cm 8cm 12cm - 8cm + 4cm 4cm

  8. 12cm 6cm - + 8cm 8cm 4cm 4cm 4cm Total Area = 96+40-8= 128cm2
