This question tests 3rd grade informative/explanatory writing skill of developing the topic with facts, definitions, and details (CCSS.W.3.2.b). Developing a topic means teaching readers about it using facts (true information, often with numbers/specifics), definitions (explaining important words), and details (describing, elaborating, explaining how or why). Well-developed writing doesn't just list bare facts ('Penguins swim'); it elaborates ('Penguins use their flippers like wings to swim up to 15 miles per hour, catching fish underwater'). The combination of facts, definitions, and details helps readers learn and understand the topic fully. For 3rd graders, development means adding specific information and explanation, not just mentioning the topic. In this scenario, Keisha is writing about butterflies and moths and developing it with a definition of an important word like nocturnal. The question tests whether students can identify needed definitions. Choice C is correct because it provides a definition that helps readers understand the important word 'nocturnal' used in context. For example, 'active at night' gives readers a clear understanding of vocabulary. This shows effective topic development. Choice D gives a bare fact without details or elaboration, just stating they are insects. This is common when students list facts from research without explaining or elaborating. This happens because students may think facts alone are enough, or may confuse informative writing with list-making, or may not understand that 'developing' means elaborating and explaining, not just stating. To help students develop topics with facts, definitions, and details: Teach FAD (Facts, And Details): Every fact needs details to develop it. Model expanding bare facts: 'Penguins eat fish' → 'Penguins eat fish like anchovies and sardines, catching them underwater with their sharp beaks.' Practice definitions: When you use important word, explain what it means for readers. Use elaboration prompts: 'Say more about that,' 'Give an example,' 'Explain how,' 'Tell why.' Create development checklist: □ Specific facts (with numbers/names/details)? □ Definitions for hard words? □ Details that describe/explain/elaborate? Compare bare vs developed writing side-by-side. Use mentor texts: highlight facts in one color, definitions in another, details in third. Teach sentence expansion: Start with fact, add 'how,' 'why,' 'when,' 'where' details. Watch for: Bare lists of facts without elaboration. Vague statements ('it's interesting'). Opinions mixed with facts ('best,' 'I think'). Facts without context or explanation. Praise: 'You gave a fact AND added details that help readers understand!'

For example, mentioning predators like sharks gives readers a detailed picture of how the shell functions in the topic. Choice D gives a bare fact without details, just stating 'Sea turtles swim' without explaining how or why. This is common when students list facts from research without explaining or elaborating.

In this scenario, Emma is writing about how libraries work, developing with facts about lending and a definition of librarian; the question tests whether students can identify the sentence that provides a definition to help readers understand the topic. Choice D is correct because it provides a definition of 'librarian,' explaining their role in helping find books and use catalogs. For example, this definition gives readers a clear understanding of key vocabulary in the library process. Choice A gives a bare fact without details or definition, just stating libraries lend for free without elaborating.

Choice B is correct because it adds a detail that elaborates on the fact about evaporation by explaining how it happens and a specific invisible aspect. For example, 'The sun warms the water, and the vapor rises into the air even though you cannot see it' gives readers a detailed picture of the process. This shows effective topic development.

For 3rd graders, development means adding specific information and explanation, not just mentioning the topic. In this scenario, Carlos is writing about rainforests and developing it with a definition of canopy and facts about rain; the question tests whether students can identify what Carlos defines to help readers understand rainforests. Choice B is correct because it identifies 'canopy' as the term defined, providing a definition that helps readers understand this key part of rainforests. For example, explaining canopy as the layer of treetops gives readers a clear understanding of vocabulary and its role in the ecosystem. Choice A identifies 'rain,' but the writing doesn't define it, just mentions it vaguely. This is common when students use technical words without defining them.
