"The community provides an environment in which individual mathematical ideas can be expressed and tested against others' ideas...This enables learners to become clearer and more confident about what they know and understand." (Fosnot, Constructivism revisited: Implications and reflections. The Constructivist, 16. 2005, p.10)

"...children, in learning to mathematize their world, will come to see mathematics as the living discipline it is, with themselves a part of the creative, constructive mathematical community, hard at work." (Fosnot & Dolk, 2001, p.13)
