Mathematics – Multi-age – Year A – Unit 5

New shapes can be made by joining (combining) or partitioning (breaking apart) existing shapes – exploring two-dimensional shapes' attributes and features.

Mathematics K-2 Syllabus © 2021 NSW Education Standards Authority (NESA) for and on behalf of the Crown in right of the State of New South Wales.

In this unit students will learn to:

  • identify and describe two-dimensional (2D) shapes
  • explore how shapes can be made by joining (combining) and breaking apart (partitioning) existing shapes
  • classify shapes based on their attributes as that shape (features of triangles, circles, squares, rectangles, quadrilaterals, hexagons, octagons, polygons)
  • manipulate shapes and objects to halve them in different ways. Sometimes, halves are made up of more than one part
  • describe the position as about halfway, more than halfway or less than halfway
  • create new shapes by adding or removing sides and vertices (corners)
  • explore how 2D shapes can be classified into different categories according to their features
  • turn shapes to fit into a space or create a design
  • create linear patterns with shapes that transform (slide and reflections)
  • make designs which have a line of symmetry.
