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

      Thank you so much for sharing for free - this has saved me at least an hour of work on this Sunday afternoon.

    Practice questions, homeworks and assessments

    • 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.

    • 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.

      mattdavey919 years ago5

      Amazing use of higher order thinking skills! Great idea with clumsy Clive too!

    • PPT with answers to RAG worksheet on finding the area of a triangle. Created for a Year 8 group of level 4-5, but can be used with other years. Feedback would be appreciated - now with amended ppt
