5. Lesson Objective Calculate the area of shapes. Lesson Outcomes Correctly multiply decimals to calculate the area of at least 5 rectangles (all). Correctly substitute numbers in a formula to calculate the area of at least 5 circles (most). Correctly combine the areas of 2 shapes to calculate the area of at least 5 compound shapes (some).

6. Area of Rectangles Underpinning skill = multiply pairs of numbers, particularly decimals: a) 75 x 3.4 = b) 2.8 x 46 = c) 115 x 2.7 = d) 3.1 x 4.9 = e) 6.12 x 7.3 = 255 128.8 310.5 15.19 44.676

7. Applying this skill The rectangular banquet hall needs new floor wood panels. It measures 28m long and 9.42m wide. What is it’s area? 263.76m²

8. Developing the skill. St. George wants a flag made so he can wave it after slaying the dragon. He wants it to be 2.3m long and 80cm high. What will its area be? 1.84m² OR 18,400cm²

9. Independent activity Skillswise worksheet 1 Extension St. George wants a rectangular section of ground prepared for swordsmanship training: He wants the area of the space to be 60m². What could the dimensions of the training ground be?

10. Formula The area for a rectangle can be written as a formula: Area of rectangle = LW π = value of 3.14 r = radius ² = squared means the value multiplied by itself The area of a circle is calculated using this formula: Area of circle = π r²

11. Area of circle 78.5cm² What is the area of this cart’s wheel? It has a radius of 5cm.

12. Compound Shapes What is a ‘compound shape’?

13. Area of a compound shape This is the plan view of St. George’s bedroom. What is the area of the room? 72cm² 11 cm 8 cm 6 cm 2 cm

14. Area of Compound Shape This is the draw bridge from the castle. What is its area? 6.2m 4m Area of rectangle 4 x 6.2 = 24.8 Area of circle r² = 2 x 2 = 4 π r² = 3.14 x 4= 12.56 Area of semi-circle 12.56 ÷ 2 = 6.28 24.8 + 6.28 = 31.08m²

15. Independent Activity Computer Activity Bitesize – Area Test Bite quiz. Make a note of your scores on your lesson Area session sheet.

16. Lesson Objective Calculate the area of shapes. Lesson Outcomes Correctly multiply decimals to calculate the area of at least 5 rectangles (all). Correctly substitute numbers in a formula to calculate the area of at least 5 circles (most). Correctly combine the areas of 2 shapes to calculate the area of at least 5 compound shapes (some).
