What This Standard Means
What Students Need to Do
- Students state an opinion and explain why they hold it. They connect each reason to accurate facts, examples, or specific details that make the reason convincing.
What Mastery Looks Like
- A student can write a clear opinion, give two relevant reasons, and support both with specific evidence. The reader can tell how each fact or detail strengthens the opinion.
Common Misconceptions
- Students often repeat their opinion instead of adding evidence. They may use vague lines such as "It is better" or include details unrelated to the reason. Some treat personal feelings as facts.
How to Assess It
- Fact box: recess provides physical activity, allows peer interaction, and reduces class time. Ask, "Should fourth graders have daily recess?" Students give two reasons and support each with one fact.

Ways to Teach It
Give groups opinion, reason, fact, and detail cards; have them build matching chains and explain why each piece belongs.
Ask, "Should homework be limited to 20 minutes?" Students write a reason, then add one fact or classroom detail.
Play Evidence Match: teams pair reasons with supporting fact cards and reject one irrelevant card in each round.
Students write the principal about one playground change, using survey results and two observed details to support their reasons.
