Multi-age K–2, mathematics, Year B – Unit 04

Smaller numbers can be found hiding in bigger numbers – this unit provides opportunities to further develop students' knowledge, understanding and skills of combinations of numbers that add up to a given number.

In this unit, students will learn to:

  • recognising and representing numerals to 10
  • counting small collections of objects
  • identifying combinations of 2 numbers that add up to numbers less than 10
  • representing numbers 0–20 with drawings, numerals, symbols, and words
  • counting with one-to-one correspondence, recognising that the last number name represents the total number in the collection
  • using a ten-frame to represent smaller parts of a number
  • exposure to representing numbers on a rekenrek.

Representing whole numbers – MAO-WM-01, MAE-RWN-01, MAE-RWN-02

  • Instantly name the number of objects within small collections
  • 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

Representing whole numbers – MAO-WM-01, MA1-RWN-01, MA1-RWN-02

  • Part A – Use counting sequences of ones with two-digit numbers and beyond
  • Part A – Represent numbers on a line
  • Part A – Represent the structure of groups of ten in whole numbers
  • Part B – Use counting sequences of ones and tens flexibly
  • Part B – Form, regroup, and rename three-digit numbers

Combining and separating quantities – MAO-WM-01, MA1-CSQ-01

  • Part A – Use advanced count-by-one strategies to solve addition and subtraction problems
