Rethinking How We Teach Fractions and Rational Numbers

When we look closely at standard mathematics instruction, a central bottleneck repeatedly emerges: fractions are almost universally introduced as an isolated, self-contained chapter of arithmetic rather than an organic, structural extension of our number system. By over-relying on elementary visual metaphors like pizzas, pie charts, and chocolate bars during early primary education, we accidentally construct deep conceptual walls that students must agonizingly unlearn when transitioning to middle school algebra and high school math.
