  1. Team Worker Creative Thinker Effective Participator Independent Enquirer Reflective Learner Self Manager Real life cross/curricular links? Where are we in our journey? Which ones are you using? PLT Skills LESSON OBJECTIVES Always aim high! We are learning to: • Finding connections between different words. (Which PLT skills?) • Accurately calculate the perimeter of a semi-circle. (Grades C) AUTHOR www.mistrymaths.co.uk

  5. Which ones are you using? Team Worker Creative Thinker Effective Participator Independent Enquirer Reflective Learner Self Manager PLT Skills PERIMETER OF SEMI-CIRCLES TASK (GRADE C) EXTENSION (GRADE C) 1) Find the perimeter of the semi-circles: 1) Calculate the perimeter of the quadrant below: (a) (b) (c) 9cm 22cm 4cm 3cm 5cm Find the perimeter of the semi-circles: 2) (a) (b) (c) 3m 8cm 2) 3) A semi-circular protractor has a diameter of 10cm: Which is the correct length for the perimeter of the protractor? Show your working out.

  6. Which ones are you using? Team Worker Creative Thinker Effective Participator Independent Enquirer Reflective Learner Self Manager PLT Skills PERIMETER OF SEMI-CIRCLES MINI-PLENARY A semi-circle has arc length 20cm. Work out it’s diameter. 20cm Arc length of semi-circle= 20cm= 20 x 2= = = = 12.7cm

  7. Which ones are you using? Team Worker Creative Thinker Effective Participator Independent Enquirer Reflective Learner Self Manager • LINK BACK TO OBJECTIVES • Accurately calculate the perimeter of a semi-circle. What grade are we working at? DISCOVERY PLT Skills

  8. PLENARY ACTIVITY EXAM STYLE QUESTION (GRADE C) Calculate the perimeter of the shape below: 12.56cm A Semi-circle of diameter = 4cm Semi-circle of diameter = 4cm 4cm Semi-circle of diameter = 8cm 4cm 4cm B C 6.28cm 6.28cm Arc length of semi-circle A = Arc length of semi-circle B or C = Arc length of semi-circle A = Arc length of semi-circle B or C = 6.28cm 12.56cm Arc length of semi-circle A = Arc length of semi-circle B or C = Perimeter = 12.56cm + 6.28cm + 6.28cm = 25.1cm (1d.p.)

  9. What grade are we working at? Where are we in our journey? What have you learnt? Draw your brain In your brain, write or draw everything you can remember about calculating the perimeter of a semi-circle. It can be a skill or a reflection, or something else that might be prominent in your brain.
