Assessment

Learning Outcome 3: The learner will be able to describe and represent characteristics and relationships between two-dimensional shapes and three-dimensional objects in a variety of orientations and positions.

Assessment Standard 3.1: We know this when the learner recognises, visualises and names two-dimensional shapes and three-dimensional objects in natural and cultural forms and geometric settings, including those previously dealt with and focusing on:

3.1.1: similarities and differences between tetrahedrons and other pyramids;

3.1.2: similarities and differences between rectangles and parallelograms.
