Fraction Sense Intervention

Fraction Sense Intervention is a research-based mathematics intervention for sixth-grade students with or at risk for mathematics difficulties. The intervention aims to build understanding of fraction magnitudes using a number line approach centered on a meaningful context of a color run race. Students receive 21 lessons in small groups of four students, with each lesson lasting approximately 45 minutes. The intervention teaches key fraction concepts using a narrow range of denominators (halves, fourths, eighths, thirds, sixths, and twelfths) to develop deep understanding. Lessons include six predictable activities: warm-up, exercises (oral counting), huddle (explicit instruction), practice, sprint (multiplication fluency), and cool-down. The intervention uses explicit and systematic instruction, visual number line models, partitioning activities, and multiplicative reasoning development. Trained research assistants deliver the intervention during the school's regular mathematics intervention period.
