Being a part of the Teaching for Mastery Embedding Work Group has allowed me to collaborate with maths teachers from across London. It has improved my planning greatly and made me think carefully about misconceptions as I create questions for the class. Having the opportunity to observe a showcase lesson by a Shanghai maths teacher and then ask them questions about pedagogy and lesson design was really useful. What I have learned has helped shape our KS3/4 maths curriculum in school, which is being re-planned using Teaching for Mastery principles. It has also helped me break down difficult GCSE problem solving questions by understanding how to combine different aspects of maths.
