In this chapter we are concerned to understand the connection that can occur for primary school children between relevant practical, "hands-on" engagement with the material world in partnership with others and the development of mathematical commitment, enthusiasm and understanding. We draw on our personal experiences of children who, as part of a theory driven intervention, prepared for a mathematical exhibition by working on extended tasks which they then displayed and explained. We use the writings of David Jardine on time and Peter Applebaum on work to aid our thinking. We point to how absorbing, extended practical work recognises and calls forth our humanity and can provide purposeful spaces for making mathematics.
