Experimenting with Functions: a week of ready-to-teach maths

Five days of lessons for Year 10 Algebra. Print this pack and the week is prepared.

AC9M10A05
experiment with functions and relations using digital tools, making and testing conjectures and generalising emerging patterns

Start here: five minutes to Monday

  1. Skim the week at a glance.
  2. Print the five days (plan + worksheet each).
  3. Cut out the card sheet once.
  4. Open the free interactive unit on your board.
  5. Teach from the plan.
