This article makes use of division of fraction, a topic in Primary 5, as an example to illustrate the features of the spiral “bianshi” curriculum. The main characteristic of the curriculum is its focus on the difficulty of the problem and the more deliberate and systematic use of the “one problem, many variations” and “one problem, multiple solutions” approach to show how concepts and methods are connected. The approach stresses scaffolding of learning and at the same time emphasizes the integration of the curriculum focus and problem difficulty within the context of mathematical structures.
