In 2019 Lyndale Greens Primary School were one of the forty schools involved in MAV and MSTEG’s two year collaborative project. Implementing school-wide change was a balancing act and a challenge however, our Numeracy leadership team effectively implemented changes that provided a big impact in our Numeracy teaching and learning. In this session, we reflect on our big take aways and share how we implemented our project to build school-wide capacity around Talk Moves. We will share our successes, challenges, and the benefits of working and learning together with our aspiring leaders throughout the project.
