Test Grade 3–5 students' understanding of equivalent fractions using area models and number lines. Tasks include identifying and generating equivalent fractions from shaded area diagrams and labeled number-line points; completing missing numerators or denominators to create equivalent pairs; drawing and labeling simple area partitions or number-line segments to justify equivalence; and writing brief explanations of reasoning. Denominators will be within 2–12 and items emphasize visual justification and conversion between models.
