Complete Sentences and Fragments Worksheet — Grade 2

Practice spotting complete sentences and fragments in Grade 2 with this three-part worksheet covering subjects, predicates, and missing parts.

Every sentence needs two parts to be complete: something to name who or what the sentence is about, and something to tell what happens. When one of those parts is missing, the group of words is called a fragment. Learning to tell sentences from fragments is one of the first steps toward clear, confident writing. This worksheet gives Grade 2 students three kinds of practice: finding the naming part in a complete sentence, filling in a missing word to complete a fragment, and choosing whether a group of words is a sentence or a fragment. Work through each part in order. Read every group of words aloud if it helps — hearing the difference between a complete thought and an incomplete one is a powerful strategy at this age.

Complete Sentences and Fragments Worksheet — Grade 2

Read each group of words carefully. Look for a naming part and an action part to decide if it is a complete sentence.

Remember

  • A complete sentence has a naming part and an action part. Example: 'The cat purrs.' has both.
  • A fragment is missing a part. 'Runs fast.' has no naming part. 'The cat.' has no action part.
  • Fix a fragment by adding the missing part. 'In the pond.' can become 'A frog sits in the pond.'

What this worksheet teaches

  • Identify the naming part in a complete sentence written at the Grade 2 level.
  • Complete a sentence fragment by writing in the missing subject or predicate.
  • Recognize whether a group of words is a complete sentence or a fragment.

What is on the page

Part C — Choose the best answer prints “Which group of words is a complete sentence?” with the options “The big yellow bus.”, “Rosa rides the big yellow bus.” and “Rides to school.”; the key gives “Rosa rides the big yellow bus.”.

The language it drills

“The brown cat sleeps on the rug.” has one answer in the key: “The brown cat”.

Notes for the grown-up

  • Students often write a naming part alone, like 'My cat.' and think it is a sentence. Watch for this error.
  • Ask the student to say the sentence aloud. If they add words naturally when speaking, guide them to write those words too.
  • The student is ready to move on when they spot and fix fragments in their own writing without being prompted each time.
