In this unit – 'Collections of objects can be changed by adding more (combining) or taking some away (separating)', students are provided with opportunities to:

  • separate and take away part of a group to determine how many
  • compare 2 or more groups to determine equality or how many more
  • combine 2 or more groups to identify the relationship between the parts and the whole.

Representing whole number – MAO-WM-01, MAE-RWN-01, MAE-RWN-02

  • Instantly name the number of objects within small collections
  • Recognise number patterns
  • Use the counting sequence of ones flexibly
  • Connect counting and numerals to quantities

Combining and separating quantities – MAO-WM-01, MAE-CSQ-01, MAE-CSQ-02

  • Model additive relations and compare quantities
  • Identify part-whole relationships in numbers up to 10

Forming groups – MAO-WM-01, MAE-FG-02

  • Investigate and form equal groups by sharing
  • Record grouping and sharing

Data – MAO-WM-01, MAE-DATA-01

  • Respond to questions, collect information and discuss possible outcomes of activities
  • Organise objects into simple data displays and interpret the displays
