Outcomes & Indicators
 Early Stage One SGES1.2: Manipulates, sorts and describes representations of two-dimensional shapes using everyday language. Indicators: Manipulate, sort and describe two-dimensional shapes.Identify and name circles, squares, triangles and rectangles in pictures and in the environment, and presented in different orientations.Represent two-dimensional shapes using a variety of materials. Identify and draw straight and curved lines. Stage One SGS1.2: Manipulates, sorts, represents, describes and explores various two-dimensional shapes. Indicators: Identify, name, compare and represent hexagons, rhombuses and trapeziums presented in different orientations.Make tessellating designs using flips, slides and turns.Identify a line of symmetry.Identify and name parallel, vertical and horizontal lines.Identify corners as angles.Compare angles by placing one angle on top of another. Stage Two SGS2.2a: Manipulates, compares, sketches and names two-dimensional shapes and describes their features. Indicators: Identify and name pentagons, octagons, and parallelograms presented in different orientations. Compare and describe special groups of quadrilaterals. Make tessellating designs by reflecting, translating and rotating.Find all lines of symmetry for a two-dimensional shape. SGS2.2b: Identifies, compares and describes angles in practical situations. Indicators: Recognise openings, slopes and turns as angles.Describe angles using everyday language and the term 'right'. Compare angles using informal means. Stage Three SGS3.2a: Manipulates, classifies and draws two-dimensional shapes and describes side and angle properties. Indicators: Identify right-angled, isosceles, equilateral and scalene triangles.Identify and draw regular and irregular two-dimensional shapes.Identify and name parts of a circle.Enlarge and reduce shapes, pictures and maps.

 File Description This file is designed for Stages 1 and 2. It introduces the flip (reflection), slide (transformation) and turn (rotation) using a character called Motion Man. Students use the interactive tools to slide, rotate and flip the character according to instructions. An introduction to the basic angles - acute, obtuse and right angle. Suitable for Stage 2. Introduction to formal angle names. Definitions and activities for practice. Stage 2 Identifying lines of symmetry in dot patterns. Stages 1-2 A simple introduction to symmetry of 2D shapes. Stage 1. Introduces octagons. Investigates regular v irregular shapes. Stage 1 Properties of 2D shapes, includes a section on regular v irregular shape. S1 - 2. Revises basic 2D shapes and their properties before looking at the differences between regular and irregular polygons. Stage1 Introduction to parallel lines. Find the parallel lines in the three drawings. Stage 1 Identifying different types of lines. Stage 1 Activities using polyominoes. S2 Create different polygons by flipping, sliding and turning the shapes provided. Try these tangram challenges. Step by step directions on making your own tangram puzzle. Stacks of activities and clues to remember the names and properties of all the different triangles. S3.
