This paper discusses group learning among VCE mathematics students at a combined schools' workshop in Hamilton, Victoria, and at Gippsland Grammar. When tasks with the potential for collaborative groups to discover complexities are used in conjunction with a teaching approach like class collaboration students tend to engage with the tasks, more frequently display the types of characteristics possessed by talented mathematicians, and develop new mathematical understandings. Anecdotal evidence suggests that the tks described in this paper are suitable for such a purpose.
