Abstract
A review of the literature to gUide the development of a coherent teaching program on
percent for Year 8 students revealed varied alternatives and little consensus. Working from
the premise that fundamentally percent is a proportion, the proportional number line method
was created to assist students experience success in percent problem solving, to also promote
conceptual understanding of percent as a proportion, and to embody the multiplicative
structure of percent situations. Classroom research indicated that students readily adopted
the method.
