Secondary Mastery Professional Development
Materials that will assist you in your professional development and support you in teaching for mastery with confidence
These materials offer a ‘fine-grained’ description of the key themes and big ideas of the national curriculum by detailing:
- six broad mathematical themes
- a number of core concepts within each theme
- a set of ‘knowledge, skills and understanding’ statements within each core concept
- a collection of focused key ideas within each statement of knowledge, skills and understanding.
