  1. Lesson Plan – Rectangles

  2. Starter Activity Complete the ‘Heard the Word’ table and then fold it in half and glue it into your book.

  3. Today we are learning I am starting the lesson on level _____________________ By the end of this lesson I want to be able to _____________________

  4. On your mini white boards describe what I mean by the perimeter of this rectangle.

  5. On your mini white boards describe what I mean by the area of this rectangle.

  6. How could we calculate the perimeter of the black rectangle?

  7. How could we calculate the area of the black rectangle?

  8. 7 4 Area of a rectangle

  9. How could we calculate the perimeter of this rectangle? 5cm 3cm

  10. How could we calculate the area of this rectangle? 5cm 3cm

  11. How do we calculate the perimeter of any rectangle or square? width length We add two lots of the length and two lots of the width! A = l + l + w + w

  12. How do we calculate the area of any rectangle or square? width length We multiply the length by the width! A = l x w

  13. Find the area of this shape: 2cm 2cm 5cm 5cm

  14. Today’s Task • Match the different shapes to their areas and perimeters. • The groups does not need to match all of the shapes, it is more important that each person works on a shape that challenges them. • If necessary two people could work on the same shape and compare their answers. • For each shape you must show how you worked out the area and the perimeter. • You cannot glue a matching pair onto your A3 paper unless the rest of the group agree with your method. • If you complete both the * shapes (these are the challenge shapes) draw a challenge shape of your own and work out the area and the perimeter.

  15. 2cm 3cm 7cm 2cm 8cm 8cm * 10cm 5cm 10cm 12cm 12cm 7cm This path is 2cm wide all the way around. 3cm 17cm 7cm * 7cm
