Some projects lend themselves to cross-curricular working, allowing for collaboration across different subjects.  This helps teachers to work in a different way and with other members of staff, and enables pupils to see the real-world links and transferable skills the project is promoting.

The Northern Saints consortium enlisted the help of faciltators to take some of their pupils on a week-long cross-curricular Design Sprint.  The pupils not only worked across subjects, but across year groups and schools too.

Thornhill Academy in Sunderland drew on its local business resources to develop a project on the Automotive Industry.  Working in collaboration across a variety of subjects within the school, as well as a number of local businesses, the project looked at the life cycle of a car from conception and design through to scrappage.

Valley Gardens Middle School in Whitley Bay decided to embed a PBL approach across the whole school.  To enable this, they created a two week timetable and allocated every other Wednesday afternoon to PBL.  Pupils undertook a different project each term, rotating within their year group.  All staff were involved in the planning and teaching of the projects, and regular review and reflect sessions meant that they were constantly adapted and "tweaked".
