Aligned to CCSS.ELA-LITERACY.RI.3.1, this resource requires students to "Ask and answer questions to demonstrate understanding of a text." By engaging with facts about polyps and ocean acidity, students build the rigor to move from literal to inferential reasoning. This code can be copied directly into lesson plans or IEP goals.

Use this worksheet as a formative assessment after a science lesson. A concrete use case involves having students highlight the sentence in their passage that provides the answer. Teachers should observe if students are returning to the text; if students struggle with the True/False section, it indicates a need for keyword-scanning instruction.

This worksheet is for grades 3 through 4 and serves as an excellent scaffold for English Language Learners. It pairs naturally with non-fiction books or anchor charts detailing informational text structures. The inclusion of technical vocabulary like "acidity" makes it a valuable tool for cross-curricular science and literacy instruction.

According to the RAND AIRS 2024 report on literacy instruction, providing students with structured, evidence-based tasks significantly improves their ability to retain complex scientific information. This worksheet targets the CCSS.ELA-LITERACY.RI.3.1 standard by requiring students to extract specific details about coral reefs, such as the role of polyps and the impact of ocean acidity on skeletal structures. By completing these 10 tasks, students move beyond surface-level reading and develop the critical thinking skills necessary for advanced informational text analysis. Research from the NAEP consistently shows that students who engage in frequent, focused comprehension practice score higher on standardized reading assessments. This resource offers a high-utility, low-barrier entry point for developing these essential skills in a classroom setting, ensuring that every learner has the opportunity to achieve mastery through supported practice while maintaining high expectations for scientific literacy.
