Using the three versions

  • Start everyone with the same short explanation, then hand out Support, Core or Challenge.
  • Question numbers line up across the versions, so you can go through the answers with the whole class.
  • The PDF has a cover page and each version on its own pages; the answer keys PDF has all three keys.
