Assess students' ability to recognize, generate, and explain equivalent fractions using area (region) models and number lines. Tasks include matching shaded region diagrams to fraction notation, partitioning shapes to show equivalent values, placing and labeling equivalent fractions on number lines, finding missing numerators or denominators that create equivalence, and writing brief visual justifications. Aligned to Grades 3–5, medium difficulty, focused on conceptual understanding and translating between representations.
