Third - Shape, position and movement

Standard 3.GMD.1.2 - Practice calculating and constructing angles with a protractor.

Included Skills:

Angle, symmetry and transformation
• I can name angles and find their sizes using my knowledge of the properties of a range of 2D shapes and the angle properties associated with intersecting and parallel lines.
• Having investigated navigation in the world, I can apply my understanding of bearings and scale to interpret maps and plans and create accurate plans, and scale drawings of routes and journeys.
• I can apply my understanding of scale when enlarging or reducing pictures and shapes, using different methods, including technology.
• I can use my knowledge of the coordinate system to plot and describe the location of a point on a grid.
• I can illustrate the lines of symmetry for a range of 2D shapes and apply my understanding to create and complete symmetrical pictures and patterns.
• Names angles using mathematical notation, for example, ? ABC.
• Identifies corresponding, alternate and vertically opposite angles and uses this knowledge to calculate missing angles.
• Uses the angle properties of triangles and quadrilaterals to find missing angles.
• Applies knowledge and understanding of scale to enlarge and reduce objects in size showing understanding of linear scale factor.
• Uses bearings in a navigational context, including creating scale drawings.
• Identifies all lines of symmetry in 2D shapes.
• Creates symmetrical patterns and pictures.
