Let’s go through each sentence one by one.

We need to decide if it’s a complete sentence (write ‘S’) or just a fragment (write ‘F’).

Remember: A complete sentence must have:
- A subject (who or what the sentence is about)
- A verb (what the subject is doing)
- And it must express a complete thought.

1) “Played tennis.”
→ Who played? We don’t know. No subject. Just an action.
→ Fragment → F

2) “Mom and dad played tennis.”
→ Subject: Mom and dad
→ Verb: played
→ Complete thought → S

3) “Walk the dog.”
→ This sounds like a command, but who is walking? It’s missing a subject (like “You walk the dog”). In grammar, commands are sometimes considered sentences, but in this worksheet’s context (Grade 1), they’re likely treating it as a fragment because there’s no clear subject stated. Also, the example given (“Josh brushes his teeth”) has a named subject. So we’ll treat this as a fragment.
→ Fragment → F

4) “Mary walks the dog everyday.”
→ Subject: Mary
→ Verb: walks
→ Complete thought → S

5) “Brad’s friend Bob is here.”
→ Subject: Brad’s friend Bob
→ Verb: is
→ Complete thought → S

6) “Brad’s friend Bob.”
→ Just a name — no verb, no action. Not a full thought.
→ Fragment → F

7) “Decorated tree.”
→ Who decorated? What did they do to the tree? Missing subject and possibly object/verb clarity. Sounds like part of a sentence.
→ Fragment → F

8) “Let’s decorate the tree.”
→ “Let’s” = “Let us” — so subject is “us”, verb is “decorate”. It’s a complete suggestion/command with implied subject. In Grade 1, this is usually accepted as a sentence.
→ Sentence → S

9) “Cushions on the couch.”
→ Just describing something — no verb, no action. Not a full thought.
→ Fragment → F

10) “The cushions on the couch are soft.”
→ Subject: The cushions on the couch
→ Verb: are
→ Complete thought → S
