The kind of sentences you'll fix

Fixed: I think breakfast matters because it gives me energy.
I think game night is great because (together)
I think shelters deserve donations because (care)

What's on a 2nd grade sheet

A few of the sentences, as the answer key corrects them:

I believe kids should garden because watching food grow is exciting.
I think autumn is the best season because the leaves turn colors.
I think helping neighbors is important because kindness spreads.

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.
