The large corpus of research on mathematical reasoning and justification in the mathematics education literature has yielded a wide range of tasks that require a mathematical argument to be established. This paper presents the DIVINE framework that classifies justification tasks by their nature and purpose as well as the expected element to be provided in the justifications. The framework is then used as a theoretical basis for appraising justifications produced by mathematics teachers.
