The Oxford International Sustainability Teacher's Guides offer comprehensive support for the Project Books with detailed lesson plans and innovative ideas for teaching. There is guidance on taking learning beyond the classroom and adapting topics for your local environment and community. Each activity to be assessed as part of student projects is identified. Differentiation activities and support is offered to cater to the needs of every student, and key vocabulary is highlighted at the beginning of every lesson. A key focus of the course is its interdisciplinary nature, integrating science, English, mathematics, and many other subjects within an international curriculum for sustainability. Texts and instructions for engaging classroom activities are provided within the lesson plans.
