Stage 3 – Year A – Unit 8

This 2-week, Year A unit develops the big idea that visual representations help us understand aspects of our world (chance and position).

Students are provided opportunities to:

  • compare different position systems, including Cartesian coordinates, to define precise points on a coordinate plane
  • understand that probability can be represented numerically between zero to one
  • present probability outcomes and create random generators.
