Mathematics – Multi-age – Year B – Unit 15

This two-week unit develops student knowledge and skills in understanding that a fraction can mean half a collection or half a measure.

Mathematics K-2 Syllabus © 2022 NSW Education Standards Authority (NESA) for and on behalf of the Crown in right of the State of New South Wales.

Students are provided opportunities to:

  • engage in meaningful activities using repeated halving to explore halves, quarters or eighths
  • create and explore collections of objects that have or have not been divided into halves, quarters or eighths
  • share objects into smaller groups and recognise if the number in each group is equal or not
  • investigate division through sharing and grouping a collection, including leftovers.
Representing whole numbers – MAO-WM-01, MAE-RWN-01, MA1-RWN-01, MAE-RWN-02, MA1-RWN-02
  • Use the counting sequence of ones flexibly
  • Recognise number patterns
  • 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-01, MAE-FG-02, MA1-FG-01

  • Investigate equal groups by sharing
  • Record grouping and sharing

Geometric measure – MAO-WM-01, MAE-GM-03, MA1-GM-03
  • Length: Create half a length
