Every sentence we speak or read has to have an ending punctuation mark. We need to know when one sentence ends and another begins. How do we know if a sentence needs a period, a question mark, or an exclamation point? How do we know a question is a question instead of a statement? By the end of this lesson you will be able to recognize if a sentence is asking a question, showing emotion, or just simply a statement. Also you will be able to identify the correct punctuation that belongs at the end of that sentence.
