Fractions Across Grades 4-6: A Learning Trajectory (Teacher Professional Development)

Fractions are a central focus of the mathematics curriculum in Grades 4–6 and serve as a critical bridge from whole number thinking to proportional reasoning and algebra. In this professional development session, participants will explore how fraction understanding develops across these grade levels and how concepts progress from equivalence and operations to ratios, division, and rational numbers.

Through hands-on tasks, visual models, and rich mathematical discussions, teachers will examine common student misconceptions and learn strategies to strengthen conceptual understanding alongside procedural fluency. Emphasis will be placed on number lines, area models, and real-world problem contexts that deepen reasoning and sense-making.

Participants will leave with instructional routines and practical tools to support students in building a coherent and connected understanding of fractions across Grades 4–6.
