A.3Conciseness and relevance
Good
Criteria Feedback
- Your exploration is logically structured and easy to follow.
- Your diagrams, photos, and written explanation work well together to support the main idea.
- Your focus stays mostly relevant to the modelling task and the final design has a clear purpose.
- A few sections become less smooth because some transformation steps are omitted.
- Some background material and the optional extension slow the pace a little.
- The ending would be stronger if it tied the main mathematical method together more explicitly.

B.3Clarity and consistency
Good
Criteria Feedback
- You use appropriate mathematical language such as vectors, matrices, coordinates, and affine transformations.
- Your use of multiple representations is effective, combining sketches, photos, coordinate work, and digital diagrams.
- Your calculations are presented clearly enough that the main transformation process can be followed.
- Your notation is occasionally inconsistent, especially when points and vectors are discussed.
- Some figure labels and repeated transformations are not shown in enough detail to support complete clarity.
- A few statements about the properties of the transformations are broader than the work actually demonstrates.
