Stage 1, mathematics, Year B – Unit 40

This two-week unit develops student knowledge, understanding and skills to solve problems using critical and strategic thinking.

In this unit, 'Problems can be solved and represented in different ways', students are provided opportunities to:

  • investigate time and duration problems using calendars and clocks
  • solve addition and subtraction problems using objects, diagrams, images and models
  • record answers to multiplication and division problems (including those with remainders) using drawings, words and numerals.

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

  • Use counting sequences of ones with two-digit numbers and beyond
  • Represent numbers on a line
  • Represent the structure of groups of ten in whole numbers

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

  • Use counting sequences of ones and tens flexibly
  • Form, regroup, and rename three-digit numbers

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

  • Use advanced count-by-one strategies to solve addition and subtraction problems
  • Use flexible strategies to solve addition and subtraction problems

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

  • Represent and reason about additive relations
  • Form multiples of ten when adding and subtracting two-digit numbers
  • Use knowledge of equality to solve related problems

Forming groups A – MAO-WM-01, MA1-FG-01

  • Model and use equal groups of objects to represent multiplication
  • Recognise and represent division

Forming groups B – MAO-WM-01, MA1-FG-01

  • Represent and explain multiplication as the combining of equal groups
  • Represent multiplication and division problems

Geometric measure A – MAO-WM-01, MA1-GM-01

Position: Follow directions to familiar locations
