Editor's Notes

  • #1: 23 sq units
  • #2: What according to you is todays learning objectives? How can you describe this shape based on the animation you saw? The shape is made of two rectangles..
  • #5: How will you describe compound shapes?? (meaning - made up or consisting of several parts) Some shapes are made by joining two or more shapes together, These shapes are called compound shapes (composite shapes)
  • #6: How will you describe compound shapes?? (meaning - made up or consisting of several parts) Some shapes are made by joining two or more shapes together, These shapes are called compound shapes (composite shapes)
  • #7: How can you find the area of a compound shape? We can split the compound shape into smaller rectangles Find the area of each rectangle by the formula = l x b Add together the areas of the rectangles.
  • #11: Area A = 10 x 7 = 70 sq cm Area B = 5 x 4 = 20 sq cm Total area = 70 + 20 = 90 sq cm
  • #14: Ans 20 + 4 = 24 sq cm
  • #15: Ans 55 + 32 = 87 sq m
  • #16: Ans 10 + 8 = 18 sq m No. of boxes = 18 歎 6 = 3 boxes of fertilizer.
  • #17: Describe compound shapes. How can you find its area.
  • #18: Where do you see compound shapes in the world? How do you suppose they were designed, and how might the materials for the shape be measured out? Area of the lawn.. Flooring or carpeting for living room/ bedroom , kitchen
  • #19: Atlantis Hotel Many of the buildings in UAE is having compound shapes..
  • #20: National Bank of Abu Dhabi - Many of the buildings in UAE is having compound shapes..
  • #21: Ans 12 sq - 2 sq m = 10 sq m Cost = 10 x 20 = AED 200
  • #24: Peer assessment rubrics in the worksheet Ans = 30 + 20 = 50 sq m
