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 3rd graders, development means adding specific information and explanation, not just mentioning the topic. In this scenario, Maya is writing about the water cycle and developing with a definition and some facts with details; the question tests whether students can identify a sentence that adds an elaborating detail to a fact. 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. Choice A gives a bare fact without details. This is common when students list facts from research without explaining or elaborating.

For 3rd graders, development means adding specific information and explanation, not just mentioning the topic. In this scenario, Jamal is writing about sea turtles and developing the topic with facts like lifespan and shells, plus details about protection; the question tests whether students can identify the sentence that develops the topic with a fact and detail. Choice B is correct because it includes specific facts with numbers (up to 80 years) and details (hard shells protect from predators like sharks), elaborating on sea turtle characteristics. 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.

For 3rd graders, development means adding specific information and explanation, not just mentioning the topic. In this scenario, Maya is writing about Rosa Parks and developing it with a definition of segregation. The question tests whether students can identify needed definitions. Choice C is correct because it identifies the term 'segregation' that is defined to help readers understand the historical context. For example, defining it as 'Black and white people had to use separate areas' gives readers a clear understanding of vocabulary. This shows effective topic development. Choice A is off-topic as 'boycott' is mentioned but not defined in the report. This is common when students use technical words without defining them. This happens because students may assume readers know terms, or may not understand that 'developing' means elaborating and explaining, not just stating.

For 3rd graders, development means adding specific information and explanation, not just mentioning the topic. In this scenario, Chen is writing about sea turtles and giving some bare facts without details. The question tests whether students can identify writing that needs more development. Choice C is correct because it gives only a bare fact without developing it with details, just stating where eggs are laid. For example, 'lay their eggs on sandy beaches' lacks elaboration on how or why. This shows ineffective topic development. Choice A elaborates with details that explain how babies hatch and move. This is common when students list facts from research without explaining or elaborating.

In this scenario, Yuki is writing about rainforests with some definitions and details, but the question tests identifying a revision that adds a specific fact and detail for better development. Choice C is correct because it includes a specific fact with numbers and elaborates with a detail explaining the result. For example, 'Rainforests receive over 100 inches of rain each year, so plants grow thick and green' gives readers factual information and a detailed explanation of why. This shows effective topic development. Choice A is too vague to teach anything, using words like 'nice' without specifics. This is common when students use vague statements instead of specific facts. 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.
