Multi-age 3–6, mathematics, Year A – Unit 20

This unit develops the big idea that our number system extends infinitely to very large and very small numbers.

Syllabus

Syllabus outcomes and content descriptors 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.

In this 2-week unit, students are provided opportunities to:

  • represent and partition numbers using place value (Stage 2)
  • recognise that negative whole numbers can result from subtraction (Stage 3)
  • make connections between benchmark fractions, decimals and percentages (Stage 3)
  • create a simple map and mark locations
  • select strategies to efficiently solve problems in addition, subtraction, multiplication and division.
