For a fourth-grade student with intellectual disability, which assessment best demonstrates knowledge of rocks and the rock cycle?

• A. Filling in a concept map of the rock cycle with examples for each type of rock
• B. Sorting picture cards of rocks by age and type of rock
• C. Completing an interactive Internet activity on rocks and the rock cycle
• D. Writing an essay that describes how rocks are transformed from one type to another

Answer: (A)

Demonstrating knowledge of rocks and the rock cycle by showing how the rock types relate to each other and to the processes that transform them is best done with a concept map. A concept map lets the student organize categories (igneous, sedimentary, metamorphic) and place concrete examples next to each type, then draw arrows to the actions that create or change rocks—melting, cooling, erosion, deposition, compaction, cementation, and metamorphism. This visual, connected format supports understanding for a fourth-grader with intellectual disability because it pairs simple labels with images or icons, uses color coding, and lays out relationships clearly. By filling in the map, the student demonstrates not just knowledge of what rocks are, but how they are formed and transformed within the cycle, which shows a deeper, integrated understanding. Other approaches test pieces of knowledge in isolation or rely more on language or digital navigation. Sorting rocks by type or age emphasizes classification without showing the full cycle; writing an essay requires more language output; an interactive online activity can be useful but may not provide the same structured, concrete connections for every learner. The concept map approach combines classification, factual recall, and process relationships in a single, hands-on, adaptable format.
