Multi-age 3–6, mathematics, Year B – Unit 17

This 2-week, Year B unit develops the big idea that multiplicative thinking involves flexible use of multiplication and division concepts, strategies and representations.

Syllabus

Syllabus outcomes from 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:

  • measure and compare volume using the layer structure and recording in cubic centimetres, recognising the multiplicative structure for finding volume
  • investigate arrays and partially covered area models to support multiplicative thinking (Stage 2)
  • apply knowledge of multiplication to estimate, measure and compare area using square centimetres and square metres (Stage 2)
  • select and apply strategies to solve problems involving multiplication and division with whole numbers (Stage 3)
  • dissect two-dimensional shapes and rearrange them using translations, reflections and rotations (Stage 3).
