This course focuses on the mathematics needed in design and technology. An ideal programme of professional development for teachers of design and technology produced by a mathematics specialist in collaboration with a range of D&T experts. The course is also ideal for students studying Design and Technology GCSE, and similar, with many model solutions of mathematics applied in a D&T context and would be suitable for learning via remote learning. Further resources, including worksheets and mini quizzes, can be found on the TES website, search for \'TES goodridge18 shop\'.Following the completion of the course, teachers will have developed their subject knowledge of mathematics and enhanced their ability to successfully teach the content whilst current D&T students will improve their understanding on mathematics in design and technology. As well as learning mathematics, teachers can also learn from a range of different design and technology teachers who share their expertise and experiences of embedding mathematics into the curriculum, assessment and homework as well as their reflections on the content taught within this course. This really is a one-stop course for mathematics in design and technology.
