Stage 1, mathematics, Year B – Unit 22

Patterns have something that repeats over and over and over again – this unit develops student knowledge, understanding and skills of two-dimensional shapes and their attributes and properties.

In this unit, students will learn to:

  • sort collections using attributes and properties
  • recognise, name and explore properties of two-dimensional shapes
  • investigate repeating shape patterns that grow, shrink, radiate and are symmetrical
  • investigate repeating number patterns that grow and shrink.

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

  • Use counting sequences of ones with two-digit numbers and beyond
  • Continue and create number patterns
  • Represent the structure of groups of ten in whole numbers

Representing whole numbers B – MA1-RWN-02

Use counting sequences of ones and tens flexibly

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 – MA1-CSQ-01

  • Represent and reason about additive strategies
  • Form multiples of ten when adding and subtracting two-digit numbers

Two-dimensional spatial structure A – MAO-WM-01, MA1-2DS-01

2D shapes: Recognise and classify shapes using obvious features

Two-dimensional spatial structure B– MAO-WM-01, MA1-2DS-01, MA1-2DS-02

  • Recognise and classify shapes using obvious features
  • Represent, combine and separate two-dimensional shapes

Data A – MAO-WM-01, MA1-DATA-01

Ask questions and gather data

Data B – MAO-WM-01, MA1-DATA-02

  • Identify a question of interest and gather relevant data
  • Create displays of data and interpret them
