Multi-age K–2, mathematics, Year B – Unit 15

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

Syllabus

Syllabus outcomes and content descriptors from the Mathematics K–10 Syllabus (2022) © NSW Education Standards Authority (NESA) for and on behalf of the Crown in right of the State of New South Wales, 2024.

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.
