Pythagoras Proofs
A resource that uses interactive Excel spreadsheets to help pupils investigate a geometrical proof and an algebraic proof of Pythagoras’ theorem. The interactive spreadsheets show the stages in proving Pythagoras’ theorem. Teachers can use these to generate discussion at each step and encourage pupils to construct a proof for themselves.

Year 9 Objectives covered:
  • Investigate Pythagoras' theorem, using a variety of media, through its historical and cultural roots, including 'picture' proofs
Year 10 Objective:
  • Distinguish between practical demonstration and proof in a geometrical context
There are opportunities for:
  • Whole class teaching
  • Paired work
