ab: Proportional reasoning has been described as a watershed concept, a
cornerstone of higher mathematics. Proportionality is a fundamental
concept in middle grades mathematics and plays a critical role in
students’ mathematical development. It has important implications for
higher-level mathematics and can be seen as a link between elementary
school arithmetic and the more abstract high school mathematics.
Furthermore, it is not only important in mathematics but also in our
everyday life as many situations revolve around the idea of ratio and
proportion. In this paper, we focus on reasoning strategies that middle
grades students use when solving proportional word problems. In
addition, we discuss the concept of proportional reasoning and briefly
describe the developmental trajectory of proportional reasoning.
