What if your classroom wasn't just a place where teaching happens . . . but a tool that makes teaching easier? In this groundbreaking book, educator and behaviour specialist Jen Foster shows you how the classroom itself can act as a third teacher - shaping behaviour, boosting engagement, supporting regulation, and reducing the invisible drains that make school harder for children and teachers. Drawing on neuroscience, psychology, and years of practice in schools, Foster reveals why so many classrooms run on default settings that exhaust children's body budgets and how simple, intentional design choices can transform them into spaces where pupils feel safe, connected and ready to learn. Inside you'll find: *A new framework for Classroom by Design, built around connection, regulation, neuroinclusion, management and engagement *Research-backed insight into how environments influence behaviour, attention and emotional wellbeing *Practical, teacher-friendly strategies that save time, reduce cognitive load and make routines run themselves *Guidance for designing neuroinclusive spaces that support every child without overwhelming the teacher *Tools to help your classroom work as hard as you do - all year long This isn't a classroom setup book. It's a blueprint for building classrooms that help children flourish all year long. The essential book for every primary teacher who wants behaviour to feel easier, teaching to feel lighter, and learning to feel joyful.
