The kind of sentences you'll fix

Finish the opinion with your reason, and write the whole sentence on the line.

  1. I think beaches are the best trips because (waves)

    Fixed: I think beaches are the best trips because I love the waves.

  2. I think recess is important because (exercise)
  3. I think board games beat screens because (talk)

Every print pulls a fresh set of sentences at this level, so a make-up test or a second sibling never gets the same sheet.

What's on each sheet

Every version prints on US Letter or A4, with its answer key on the last page.

How to teach this

Challenge weak reasons gently: 'because it's good' earns the follow-up question why. Pushing one level deeper, kindly, is where reasons get real.

Watch for: The because-half is the whole game: opinions are free, but reasons are earned. A child who reaches for a real reason is doing W.1's actual work. The key's model answer is one good possibility; any complete sentence with a sensible reason counts. The cue word steers without confining.

Common questions about opinion sentence frames

What makes a good reason at this age?
Something specific and true: because they are loyal beats because they are good. The teaching notes push exactly that one step of depth.
Why the same frame every time?
Repetition of the shape frees attention for the content. The frame retires by itself once the shape lives in the writer.
