What This Standard Means
What Students Need to Do
- Students follow a person, event, process, or idea through an informational text. They explain what happened and why, using details from different parts of the text.
What Mastery Looks Like
- After reading about a flood, a student explains how heavy rain raised the river and what people did next. The student points to text details that support each part of the explanation.
Common Misconceptions
- Students may retell only the first paragraph and miss details that appear later. They may mistake what happened next for why it happened, or give a reason the text does not support.
How to Assess It
- After a short article about seed germination, ask: “What happens after the seed takes in water, and why? Use two details from the article.”

Ways to Teach It

After reading about an early flight, ask: “What problem did the pilots face, and how did they solve it? Find two supporting details.”
Read an article about rainstorms, say “streets flooded,” and have teams race to find the sentence that explains why.
