  Good resource, but right-angles are not indicated, so in theory the solutions are assumed.

  Area of triangles (with answers)

  free

  4.7

  Differentiated questions: Developing, secured and mastered question sets (can be changed to RAG)
  Developing takes students through the derivation of the formula
  Secured gives lots of practice on picking the correct values to substitute into the formula
  Mastered has problems on compound shapes and multiple step area questions to really test students' knowledge of area of triangles.
  Answers on the back as always!

  Great sheet.

  Great sheet! I added some right angles to the secure section to be on the safe side (with an old fashioned pen before I photocopied it) but I highly doubt that the kids would have worried too much about them not being explicitly stated. We had a quick "why do you think I drew the right angles on" discussion, and got on with the questions. Some people are seriously over-reacting!

  Clumsy Clive On Perimeter, Area and Volume

  free

  5

  Clive has three homework tasks on perimeter, area and volume, each getting increasingly difficult. As usual his answers are riddled with mistakes and it’s down to you to correct them, explaining where he’s gone wrong. These are intended to encourage discussion between students.

  I have corrected the error on sheet 2 mentioned in the comments - thank you!

  Brilliant resource to encourage discussion amongst students. Sheet 2, question 2, I believe Clive was actually correct. I didn't notice it before I gave the work, but it created deeper discussions between the students. Just be aware if projecting the answers.

  Last of the series ... maybe Clumsy Clive, but it is certainly AMAZING ALUTWYCHE. Thank you so much for all your amazing efforts in sharing.
