In this paper, we do three things. First we discuss the concept of the 3Rs in the anglophone world in the 20th century. Second, we briefly view 3Rs in the context of environmental concerns. Third, we elucidate the three Rs in design education and practice, a concept which we have originated without reference to preliminary models other than Reading, Writing and ‘Rithmetic and Reuse, Repurpose and Recycle. We strive to remain a theoretical as we promote the consideration and inclusion of the full range of technologies in our teaching from the simplest to the more complex, plus the ancient to the most recent of materials, tools and processes for designers. Within each range we look to development of the broadest possible material and skills Repertoire for each designer.
