Lesson 1: End Marks and Abbreviations

In this Grade 6 grammar lesson from Elements of Language, 3rd Course, students learn how to use the four types of end marks — periods, question marks, and exclamation points — with declarative, interrogative, exclamatory, and imperative sentences. The lesson also covers the correct use of periods with common abbreviations, including personal initials, academic degrees, titles, and geographical names. Practice exercises give students hands-on experience identifying sentence types and applying proper punctuation.

Section 1

Statements and Questions

Definition

A statement (or declarative sentence) is followed by a period. A question (or interrogative sentence) is followed by a question mark.

Explanation

Think of these as two sides of a conversation! A statement simply declares a fact or an opinion and ends with a period. A question, on the other hand, interrogates to get information and always requires a question mark at the end. One tells, the other asks.

Examples

  • Statement: The team captain is an excellent leader.
  • Question: Have you cleaned and organized your room?

Section 2

Exclamations and Commands

Definition

An exclamation (or exclamatory sentence) is followed by an exclamation point. A command or request (or imperative sentence) is followed by either a period or an exclamation point.

Explanation

These sentences convey urgency and emotion! An exclamation shows strong feeling like joy or shock and always gets an exclamation point. A command or request tells someone to do something. Use an exclamation point for a forceful command, or a period for a more polite request.

Examples

  • Exclamation: That concert was absolutely spectacular!
  • Command (Strong): Pass the ball now!
  • Request (Polite): Please help me set the table.

Section 3

Periods in Abbreviations

Definition

Use a period after certain abbreviations.

Explanation

Periods are crucial for showing that a word has been shortened. You must use them for initials in a personal name (like C. S. Lewis), for titles accompanying names (like Mrs. or Dr.), for academic degrees (like B.A. or M.D.), and for some geographical names.

Examples

  • The author's full name is John R. R. Tolkien.
  • My dentist is named Dr. Sharma, D.D.S.
  • We are moving to 123 North Elm St.
  • The meeting is scheduled for 9:30 A.M.
