Assessment

Learning Outcome 3: The learner will be able to use appropriate measuring units, instruments and formulae in a variety of contexts.

Assessment Standard 3.4: We know this when the learner uses the vocabulary and properties of rotations, reflections and translations to describe the relationships between distinct two-dimensional shapes and three-dimensional objects within patterns (including transformations and symmetry).
