The kind of sentences you'll fix

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

  1. I think kind words matter because (day)

    Fixed: I think kind words matter because they can fix a whole day.

  2. I believe homework should be short because (play)
  3. I think our class needs plants because (calm)

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

Flip the frame: give the reason, ask for the opinion it supports. Reasons-first thinking is the skeleton of every essay they will ever write.

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

How does this connect to real assignments?
Opinion paragraphs and persuasive letters all start with this sentence. A child fluent in the frame begins every such assignment already moving.
What is the linking-words connection?
Because is the first linking word; the transitions page in this section adds also, another, and finally, the words that grow one opinion into a paragraph.
