Criterion B: Mathematical presentation

The “mathematical communication” criterion assesses to what extent the student has:

• used appropriate mathematical language (notation, symbols, terminology). Calculator and computer notation is acceptable only if it is software generated. Otherwise, it is expected that students use appropriate mathematical notation in their work
• defined key terms and variables, where required • used multiple forms of mathematical representation, such as formulae, diagrams, tables, charts, graphs, and models, where appropriate  used a deductive method and set out proofs logically where appropriate                                              Examples of level 1 can include graphs not being labelled, consistent use of computer notation with no other forms of correct mathematical communication.
• Level 4 can be achieved by using only one form of mathematical representation as long as this is appropriate to the topic being explored. For level 4, any minor errors that do not impair clear communication should not be penalized.
