About Complete Sentences
What this skill is
A complete sentence expresses a full thought and contains both a subject (naming who or what) and a predicate (telling what they did or are), beginning with a capital letter and ending with appropriate punctuation.
When children learn it
Speaking in complete sentences begins in kindergarten (CCSS SL.K.6). Writing complete simple sentences with capital letters and end punctuation is mastered in 1st and 2nd grade (CCSS L.1.1.j, L.2.1.f).
Teaching Tips
- Ask the two-part test: "Who did it?" and "What happened?". If either part is missing, the sentence is a broken fragment that needs repair. Have your child fix incomplete worksheet items by adding the missing person or missing action.
Common Mistakes
- Treating descriptive fragments like "Running in the park" as complete sentences because they contain action words.
- Writing incomplete thoughts that lack a subject, leaving the reader wondering who performed the action.
- Dropping capital letters or end punctuation marks when writing quickly.
