How do periods and question marks help readers?
A tiny mark at the end of a sentence helps a reader understand what the words are doing. A period can finish a statement. A question mark can finish a question.
In the diagramMarks at the ends of sentencesA statement tells. A question asks.The cat sleeps.Does the cat sleep?The words tell about an animal.Period: statement. Question mark: question.
“The cat sleeps.” tells something about the cat. The period marks the end of that statement. “Does the cat sleep?” asks about the cat instead. The question mark shows that the sentence is asking.
The words change too. Adding a question mark alone does not always make the same words a clear question. Words and marks work together to help someone read the message.
A sentence can end before the whole story ends. The mark gives the reader a small boundary, showing where one complete message stops and another can begin.
About this explanation
Starting knowledge: Follow a short read-aloud sentence and notice the mark at its end; adult reading support is welcome.
