  2. Hi all  , happy Monday! This is your final 7 weeks of primary school maths! So we will use this time to consolidate and go over things to ensure you are as confident as possible when going into secondary school. This week we will be recapping angles within polygons (shapes)

  5. L.O. To compare the perimeters and areas of different squares and rectangles.

  6. What is the difference between the perimeter and area of a shape?

  7. What is the difference between the perimeter and area of a shape? The perimeter is the total length of the sides (like the fence to a garden). The area is in the INSIDE part (the garden)

  8. How do we work out the perimeter and the area of a rectangle or square?

  9. How do we work out the perimeter and the area of a rectangle or square? To find the perimeter we add up the lengths of all 4 sides. To find the area we multiply the length and width together. The answer is always in ___²

  10. Find the perimeter of these rectangles and squares. 12cm 80cm 6cm 7cm 0.5m 3m

  11. Find the perimeter of these rectangles and squares. 12cm Perimeter= 80cm 6cm 260cm Perimeter= 36cm Or 2.6m 7cm 0.5m 3m Perimeter= 28cm 12cm

  12. Find the area of these rectangles and squares. 12cm 0.25m 7cm 8cm 12cm 4m

  13. Find the area of these rectangles and squares. 12cm Area= Area= 12 x 7 0.25m 7cm 300cm² Area = 84cm² Or 3m² 8cm 12cm 4m Area= 8x8 Area= 64cm² 16m²

  14. A rectangle has an area of 36cm. What could the lengths of its sides be?

  15. Possible answers for the rectangles are: 1 and 36 2 and 18 3 and 12 4 and 9 72 and 0.5 10 and 3.6 We couldn’t have 6 and 6 because that would make a square, and we have been asked for a rectangle

  16. Possible answers for the rectangles are: 1 and 36. Do you think all 2 and 18 these rectangles will have the 3 and 12 same perimeter? 4 and 9 Work them out 72 and 0.5 and see. 10 and 3.6

  17. Possible answers for the rectangles are: 1 and 36 P= 74cm² 2 and 18 P=40cm² What do you 3 and 12 P=30cm² notice? 4 and 9 P= 26cm² 72 and 0.5 P= 145cm² 10 and 3.6 P= 27.2cm²

  18. L.O. To compare the perimeters and areas of different squares and rectangles. Your task today is quite investigative. Go back to the school’s website and download Monday’s work.

  23. L.O. To revise how the find the area and perimeter of parallelograms and triangles.

  24. Recap: how do I find the area and perimeter of a parallelogram and a triangle?

  25. Recap: how do I find the area and perimeter of a parallelogram and a triangle? Perimeter is the same for both- just add up the lengths of the 3 or 4 sides. Area= parallelograms is l x w (like rectangles or squares) triangles is ½ x b x h (because a triangle is HALF the area of a rectangle or square)

  26. Perimeters and areas: Find the perimeters and areas of these parallelograms 11m 8cm 20cm 6m 14cm 0.5m

  27. Perimeters and areas: Find the perimeters and areas of these parallelograms 11m Perimeter= 44cm 8cm Area= 112cm ² 20cm Perimeter= 34m 6m 14cm Area= 66m² Perimeter= 140cm Area= 1,000cm² 0.5m Or 10m²

  28. Perimeters and areas: Have a look at the example below on how to find the perimeter of the triangle- look closely as it requires some different lengths to the height Perimeter= 12cm + 11cm+ 11cm= 34cm Area= ½ x 12 x 7 = ½ x 84 = 42cm² 11cm 7cm 12cm

  29. Perimeters and areas: Find the perimeters and areas of these triangles 6cm 5cm 10cm 9cm 8cm 5m 7m 8cm 3m

  30. Perimeters and areas: Find the perimeters and areas of these triangles 6cm 5cm 10cm P= 20cm 9cm A= 20cm² P= 27cm 8cm A= 5m 7m 36cm² 8cm P= 17m A=7.5m² 3m

  31. L.O. To revise how the find the area and perimeter of parallelograms and triangles. Today we will be investigating and looking at parallelograms and triangles. Please go back to the school’s website and download today’s work.

  41. L.O. To find the total sum of angles in regular polygons Recap: what do we mean by regular polygons?

  42. L.O. To find the total sum of angles in regular polygons Recap: what do we mean by regular polygons? A polygon is a shape that has more than 3 straight sides. Regular means that all sides and angles are equal

  43. Today, we will be working out the interior angles of some polygons. We will NOT need a protractor. We will NOT have any angles given to us. We will simply use what we know about other shapes.

  44. Firstly, lets recap some of our polygons… Heptagon Hexagon Pentagon Octagon

  45. Firstly, lets recap some of our polygons… Heptagon (7) Hexagon (6) Pentagon (5) Octagon (8)

  46. These are regular polygons and these are irregular polygons Irregular pentagon (5) Irregular Octagon (8)
