About this worksheet
Once a child can state an opinion, the next challenge is giving a reason that actually supports it. Third graders often add a true sentence that is nearby in topic but does not prove the point. For example, trees have bark is true, but it does not explain why a playground needs more shade trees. This worksheet separates the opinion from the reason so students can check the connection. They choose matching reasons, compare weak and stronger support, and remove details that wander away from the claim. The work stays short and self-checking, which is important because a full persuasive paragraph would hide the exact skill being practiced. Encourage your child to ask, Does this sentence tell why the opinion makes sense?
What your child will learn
Match a reason to an opinion
Tell stronger reasons from weak ones
Remove details that do not support the opinion
Use because to connect an opinion and reason
Worked example
For the opinion 'The playground needs shade trees,' a strong reason is 'Shade trees keep students cooler on sunny days.'
Common mistake
Adding a sentence that is true about the topic but does not explain why the opinion is sensible.
Helpful hint
A reason should answer why the writer thinks the opinion is right.
