ABSTRACT
The topic of geometry includes developing students' knowledge about aspects such as two-dimensional shapes and three-dimensional objects, symmetry, tessellations, transformation and geometric reasoning. Geometry also includes learning about position, location and arrangement in relation to maps, plans, scaled drawings and grid systems. Topics within the geometry strand include location (position, direction, coordinates), networks (maps, scale drawing, topology), three-dimensional objects (surface, corner, edge), two-dimensional shapes (sides, angles, polygons), symmetry (line symmetry, rotational symmetry), tessellations (tiling, design, art applications), dissections (puzzles), similarity (shape, perspective) and transformations (flips, slides, turns). The geometry strand is one of the richest in terms of language. The study of geometry assists the development of visual processing—the capacity to create, manipulate and transform spatial images in the mind. Visual processing is a key skill in mathematical problem-solving across the strands.
