Read the passage: This text explains why leaves change color in fall. In summer, leaves are green because of something called chlorophyll. Chlorophyll helps the leaf make food from sunlight. When days get shorter and cooler, the leaf makes less chlorophyll. Then other colors can show, like yellow and orange. Some leaves also turn red. Finally, the leaf dries and may fall off the tree. This helps the tree rest for winter. What did the author want to do?
To tell you to rake the yard
To answer where leaves blow
To explain why leaves change color
To describe a pile of leaves
Explanation
This question tests 2nd grade ability to identify the author's main purpose for writing an informational text (CCSS.RI.2.6), specifically recognizing whether the author's goal is to explain how or why something happens or works. Every author has a REASON for writing - a purpose or goal for what they want the text to do. In informational text, three main purposes: (1) TO ANSWER A QUESTION - author poses question (like 'Why do birds fly south?') and provides answer with explanation; (2) TO EXPLAIN - author explains HOW something works/happens or WHY something is important/happens, often with steps, reasons, or causes; (3) TO DESCRIBE - author describes what something IS LIKE using descriptive details (appearance, characteristics, qualities, behaviors). Understanding author's purpose helps readers know what to pay attention to and what kind of information to expect. In this passage, the author's main purpose is to explain why leaves change color. This is clear because the text explains the reasons using words like 'because,' 'then,' with causes. For example, 'In summer, leaves are green because of something called chlorophyll... When days get shorter and cooler, the leaf makes less chlorophyll.' The overall focus is explaining, which is the author's main purpose. Choice B is correct because it accurately identifies the author's main purpose as to explain why leaves change color. This matches what the author is trying to do throughout the text: explain a process, cause, or reason. The answer uses appropriate purpose language to explain and focuses on the overall goal of the text, not just one detail. Choice A is a common error where students confuse purpose types by selecting describe when the author explains with reasons and causes. This happens because 2nd graders are learning to: (1) Distinguish between purpose types (answer vs. explain vs. describe), (2) Identify overall purpose rather than focusing on one part, (3) Use purpose language (to answer, to explain, to describe) rather than just topic, (4) Think about author's goal not their own reaction, (5) Look at whole text not one sentence. To help students identify author's purpose: Create anchor chart with three purposes and signal words/features for each: TO ANSWER A QUESTION (signals: question stated, 'Why?' 'How?' 'What?', answer provided, explanatory details); TO EXPLAIN (signals: 'This is how,' 'This is why,' 'because,' 'so,' 'the reason,' 'first, next, then,' steps or causes listed); TO DESCRIBE (signals: 'is/are,' adjectives, sensory details, 'looks like,' 'sounds like,' characteristics listed, 'what it's like'). Before reading, ask 'What do you think the author wants to tell us?' After reading, ask 'Why did the author write this? To answer a question, explain something, or describe something?' Use sentence frames: 'The author's purpose is to ___ [answer/explain/describe] ___.' Practice with varied texts: question-answer format, how-to/why explanations, descriptive passages. Model thinking aloud: 'I see the text starts with a question - Why do bees make honey? Then it tells the answer and explains. So the author's purpose is to answer that question.' Highlight purpose clues: underline question if present, circle explanation signal words (because, how, first), highlight descriptive words. Compare purpose types: Read three short passages (one answering question, one explaining, one describing same topic like 'penguins') and identify how purposes differ. Connect to writing: When students write, have them state their purpose: 'I am writing to explain how to make a sandwich' or 'I am writing to describe my cat.' Play 'Author's Purpose Sort' - sort text passages into three categories (Answer, Explain, Describe).

Have you ever wondered why bees make honey? Bees make honey to store food for later. When flowers are blooming, bees collect sweet nectar. Back in the hive, they mix the nectar and fan it with their wings. This helps the nectar turn thicker, like syrup. The honey stays in the hive for times when flowers are hard to find. Honey gives bees energy to live and work. That is why bees work so hard to make honey.
