reSolve: Assessing Reasoning: Year 3 Exemplars

This series of two exemplar tasks is designed to provoke students' mathematical reasoning and to assist teachers engage in formative assessment of students' abilities to analyse, generalise and justify. Each exemplar is aimed at Year 3, with adaptability to other years. Students analyse the task situation, form or test conjectures, and explain their thinking to others. Lesson materials include task information with suggested reasoning prompts and further activities, along with multiple annotated work samples illustrating the assessment rubric. These exemplar tasks are part of the special topic 'Assessing Mathematical Reasoning'.
