Syllabus Outcomes
MAO-WM-01 Develops understanding and fluency in mathematics through exploring and connecting mathematical concepts, choosing and applying mathematical techniques to solve problems, and communicating their thinking and reasoning coherently and clearly
MA3-2DS-01 Investigates and classifies two-dimensional shapes, including triangles and quadrilaterals based on their properties
MA3-2DS-01 Investigates and classifies two-dimensional shapes, including triangles and quadrilaterals based on their properties
Content
Two-dimensional spatial structure A
2D shapes: Classify two-dimensional shapes and describe their properties
2D shapes: Dissect two-dimensional shapes and rearrange them using translations, reflections and rotations
2D shapes: Classify two-dimensional shapes and describe their properties
- Identify and classify triangles as equilateral, isosceles or scalene triangles
- Recognise that triangles and quadrilaterals can be classified in more than one way (Reasons about spatial relations)
- Compare side and angle properties of triangles and quadrilaterals using measurement and symmetry
- Investigate the symmetry properties (line and rotational) of quadrilaterals
- Identify regular and irregular polygons
2D shapes: Dissect two-dimensional shapes and rearrange them using translations, reflections and rotations
- Use the terms translate, reflect and rotate to describe transformations of two-dimensional shapes
- Dissect and rearrange one shape to make another
- Recognise that translations, reflections or rotations change the position and orientation but not the size of shapes (Reasons about spatial orientation)
