  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: • Be reflective learners on previous learning outcomes. (Which PLT skills?) • Accurately calculate the surface area of cuboids. (Grades E-D) AUTHOR www.mistrymaths.co.uk

  2. Which ones are you using? Team Worker Creative Thinker Effective Participator Independent Enquirer Reflective Learner Self Manager STARTER PLT Skills TASK Calculate the volume for each of the following cuboids: (c) (a) (b) V = 6 x 4 x 8 V = 10 x 10 x 4 V = 5 x 10 x 20 EXTENSION (a) (b)

  8. Which ones are you using? Team Worker Creative Thinker Effective Participator Independent Enquirer Reflective Learner Self Manager PLT Skills SURFACE AREA OF CUBOIDS MINI-PLENARY Work out the surface area for the item shown: Surface Area = 2lw + 2hw + 2lh Surface Area = 2 x 20 x 8 + 2 x 30 x 8 2 x 20 x + 30 Surface Area = 480 1200 320 + + Surface Area = h l w

  9. Which ones are you using? Team Worker Creative Thinker Effective Participator Independent Enquirer Reflective Learner Self Manager • LINK BACK TO OBJECTIVES • Accurately calculate the surface area of cuboids. What grade are we working at? DISCOVERY PLT Skills

  10. PLENARY ACTIVITY Not to scale 8 cm 5 cm 8 cm 3 cm 8 cm 12 cm 8 cm Work out the surface area of the compound shape below: 64 cm2 64 cm2 40 cm2 36 cm2 64 cm2 96 cm2 64 cm2 24 cm2 36 cm2 64 cm2 96 cm2 SA = 64 + 64 + 64 + 64 + 64 + 40 + 96 + 96 + 24 + 36 + 36 = 648cm2

  11. 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 surface area of cuboids. It can be a skill or a reflection, or something else that might be prominent in your brain.
