Supporting schools to define best practice for embedding oracy in the maths classroom

Oracy and Talk for Maths

Supporting schools to define best practice for embedding oracy in the maths classroom

Oracy is a key area of the Oxford Mastery Framework. We've joined up with Voice 21, drawing upon their extensive research and experience of working with hundreds of educators, to explore oracy education and how that relates to maths. This led us to create the Talk for Maths benchmarks.

Our shared ambition is that these will help to encourage reflection, conversation and exploration of oracy in maths. They aim to support schools in creating talk-rich maths lessons, and through this, to deepen understanding and help learners grow in confidence.

The benchmarks aim to define excellent practice for oracy in the maths classroom. They have been developed as a practical framework with the aim of establishing a shared understanding for oracy and maths.


High-quality dialogue in maths has the capacity to support students to co-construct knowledge leading to deeper understanding of mathematical concepts and processes. Creating the conditions for effective classroom talk takes time but is time well spent.
