The student consistently and correctly uses correct mathematical notation, symbols, and terminology. Computer notation is present only if software-generated with clear indication. Key terms/variables are defined and explained when first introduced. The main concepts are appropriately described in the introduction. Additional terms are defined in appropriate places. The student uses multiple forms of mathematical representation: formulae, diagrams, tables, charts, graphs, and models. The degree of accuracy is stated for any rounded values, and results are rounded only at the end of the calculations thread. All calculations are provided with explanations, which are relevant to the outcomes of the work. However, the tables and drawings lack appropriate captions and descriptions, and the graphs, tables, and diagrams are not labeled at all in most instances.
