Challenging Mathematical Tasks

Challenging Mathematical Tasks is an Oxford Teacher Reference title that offers a series of comprehensive learning sequences focused on problems that students do not yet know how to solve.

This approach is based on research by Emeritus Professor Peter Sullivan, which shows that challenging tasks encourage engagement, persistence and deep mathematical understanding. The tasks are researched, developed and tested by an expert team from Monash University. Each task is supported by a clear rationale with a learning focus, key language suggestions, enabling and extending prompts and possible solutions. Curriculum alignment documents, supporting research and Blackline Masters are available on Oxford Owl.

Led by research, written by experts.

The Oxford Teacher Reference suite features a range of titles designed to extend, support, challenge and engage students of varying confidence levels. All of these titles have been written by subject-matter experts, and based off of evidence and research.
