About this worksheet

A complete sentence tells a whole idea and has a subject and a predicate: The dog barked loudly. A fragment is a piece of a sentence that leaves out the subject, the predicate or the end of the idea: Running down the street. A run-on pushes two complete ideas together without the right punctuation or joining word: The bus came we got on it. On this worksheet your child reads twelve groups of words and writes complete, fragment or run-on; the three words are in the instruction.

Building Confidence uses short, clear examples, On Level adds longer ones, and Challenge Me uses fragments that start with because or when and run-ons joined by only a comma. Ask your child to say the words aloud and listen for where one idea ends and the next begins.

What your child will learn

Tell a complete sentence from a fragment
Spot two ideas pushed together in a run-on
Say what a sentence needs: a subject and a predicate

Common Core standard: L.3.1.I

Worked example

'Because it was raining' leaves the idea unfinished, so it is a fragment. 'It was raining we stayed inside' has two ideas with nothing between them, so it is a run-on.

Common mistake

Calling a long group of words complete just because it begins with a capital letter and ends with a period.

Helpful hint

Ask: who or what, and what happened? Is there only one idea?
