This workshop is designed to support Numeracy Leaders in developing their roles and enhancing staff capacity through an observation and feedback process, and creating a mentoring and coaching cycle. I will share how I have used these processes to foster a trusting culture within my school, thereby building confidence and capacity. An effective mentoring and coaching cycle not only improves teacher capacity but also helps reduce maths anxiety. Leaders will learn how to build trust with staff, allowing them to enter classrooms with confidence and ease, work with small groups on common goals, develop an observation processes, provide relevant feedback, and build staff confidence through shared objectives. Additionally, the workshop will cover how to develop staff capacity to observe each other's practice, promote teacher professional growth and foster confidence in a supported environment
