About this worksheet

Complete sentences help readers follow who or what is doing something and where one thought ends before another begins matters in fourth grade because students are writing longer paragraphs and need sentence choices that guide a reader without confusion. Fourth graders may write a long fragment that sounds important but lacks a complete thought, or they may push two complete thoughts together without punctuation. This worksheet keeps the work inside meaningful sentences rather than isolated labels. Students identify fragments and run-ons, choose complete revisions, find subjects and predicates, and join related ideas with punctuation or conjunctions. The items rotate across identifying the feature, choosing the correct revision, explaining how the word or mark works, and rejecting common distractors. Support versions use familiar school contexts and short sentences. Standard and challenge versions add closer choices, more varied wording, and sentences where one nearby word can tempt a careless answer. Ask your child to read the whole sentence aloud before choosing. Then have them name the rule that made the answer work, because grammar becomes useful when it improves real writing.

What your child will learn

  • Tell a complete sentence from a fragment
  • Fix fragments by adding missing information
  • Fix run-ons with punctuation or joining words
  • Find subjects and predicates in complete sentences

Worked example

'Because the bridge bent' is a fragment until it is completed as 'Because the bridge bent, the team added supports.'

Common mistake

Thinking a group of words is complete just because it is long.

Helpful hint

Check for a complete thought, not just a capital letter and end mark.
