Mathematics – Stage 2 – Year B – Unit 21

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

Mathematics K–10 Syllabus © 2023 NSW Education Standards Authority (NESA) for and on behalf of the Crown in right of the State of New South Wales.

Students are provided with opportunities to:

  • partition, rename, represent and order numbers up to 6-digits
  • apply place value to recognise, name and order decimals to tenths
