Assess students' ability to compare and order proper fractions with unlike denominators using number lines and visual (area and length) models. Tasks include placing fractions on number lines, creating or interpreting bar and circle models, producing equivalent fractions or using benchmark reasoning (0, 1/2, 1) to determine greater/less, ordering sets of 3–5 fractions ascending or descending, and writing brief explanations that reference the visual models or equivalent-fraction reasoning. Problems use denominators up to 12 and emphasize conceptual analysis and justification.
