{{BR}}
= Introduction =

Commas and apostrophes are small marks with important jobs. A '''comma''' separates parts of a sentence. An '''apostrophe''' shows missing letters or possession. When you place these marks correctly, your reader can understand your meaning quickly.

In this aiMOOC, you will learn clear rules, compare correct and incorrect examples, edit sentences, and create your own writing. The course is designed for Grades 5–6.

[[File:Teaching punctuation, by J. W. Orr.png|500px|frameless|center]]

'''Learning goals:''' By the end, you can use commas in common sentence patterns, use apostrophes in contractions and possessives, explain your choices, and proofread a short text.

{{BR}}
= Why Punctuation Matters =

Punctuation gives written language structure. Compare these sentences:

'''Let’s eat, Grandma!'''

'''Let’s eat Grandma!'''

The comma in the first sentence shows that the speaker is talking to Grandma. Without the comma, the sentence has a very different meaning. Good punctuation helps you communicate safely, politely, and clearly.

[[File:English letter and punctuation frequency.jpg|500px|frameless|center]]

The chart above shows that punctuation appears often in English writing. Frequency does not tell you which mark to choose, but it reminds you that punctuation is a normal part of every text.

! Main jobs
! Example
|-
| ''','''

= Commas =

A comma looks like this: ''','''. It creates a clear boundary inside a sentence. It is not simply a place to breathe. You need a grammatical reason for using it.

[[File:Comma.svg|300px|frameless|center]]

{{#ev:youtube|https://www.youtube.com/watch?v=Wk0k2FLjM1c|500|center}}

{{BR}}
== Commas in a Series ==

Use commas to separate three or more items in a list.

'''Correct:''' We need paper, glue, scissors, and string.

The final comma before '''and''' is called the [[Serial comma|serial comma]] or Oxford comma. Some writing styles leave it out, but it can prevent confusion. Follow the style your teacher requests and stay consistent.

'''Two items usually need no comma:''' We need paper and glue.

{{BR}}
== Commas After Introductory Elements ==

Use a comma after an introductory word, phrase, or clause when it comes before the main part of the sentence.

'''Introductory word:''' Yes, I finished the chapter.

'''Introductory phrase:''' After lunch, we returned to class.

'''Introductory clause:''' When the bell rang, everyone packed up.

{{#ev:youtube|https://www.youtube.com/watch?v=NvGBug8iORE|500|center}}

{{BR}}
== Commas Between Complete Ideas ==

Use a comma before a coordinating conjunction when it joins two independent clauses. An [[Independent clause|independent clause]] can stand alone as a complete sentence.

'''Correct:''' The rain stopped, and the match began.

'''No comma needed for one shared subject:''' The rain stopped and cooled the air.

Common coordinating conjunctions are '''and, but, for, or, nor, so,''' and '''yet'''.

{{BR}}
== Commas for Direct Address ==

Use commas to separate the name or title of the person being spoken to.

'''At the beginning:''' Leo, please open the window.

'''In the middle:''' Please, Leo, open the window.

'''At the end:''' Please open the window, Leo.

A direct-address comma can change meaning. Compare '''I know, Maya''' with '''I know Maya'''.

{{#ev:youtube|https://www.youtube.com/watch?v=09-t-giMcNk|500|center}}

{{BR}}
== Commas Around Extra Information ==

Use a pair of commas around information that is not essential to identify the person or thing.

'''Extra information:''' Our principal, who loves science, visited the lab.

The sentence still identifies the principal if you remove '''who loves science'''.

Do not place commas around information that is needed to identify the noun.

'''Essential information:''' Students who finished may read quietly.

Here, '''who finished''' tells us which students may read.

{{BR}}
== Commas in Dates, Places, and Dialogue ==

In the month-day-year pattern, place a comma after the day and after the year when the sentence continues.

'''Date:''' On July 4, 2026, the museum will open early.

Separate a city and a state or country with a comma.

'''Place:''' She moved from Bristol, England, to Dublin, Ireland.

A dialogue tag often uses a comma before or after a quotation.

'''Dialogue:''' Amir said, “The bus is here.”

'''Dialogue:''' “The bus is here,” Amir said.

{{#ev:youtube|https://www.youtube.com/watch?v=uYoX_Qyknao|500|center}}

{{BR}}
== Common Comma Errors ==

'''Comma splice:''' A comma alone cannot join two complete sentences.

'''Incorrect:''' The door opened, the dog ran out.

'''Correct:''' The door opened, and the dog ran out.

'''Correct:''' The door opened. The dog ran out.

Do not separate a subject from its verb.

'''Incorrect:''' The tall oak tree, swayed in the wind.

'''Correct:''' The tall oak tree swayed in the wind.

Do not add commas just because a sentence is long. Find the sentence structure first.

{{BR}}
= Apostrophes =

An apostrophe looks like this: '''’'''. It usually has two main jobs: showing missing letters and showing possession. An apostrophe does not normally make a word plural.

[[File:Apostrophe.svg|180px|frameless|center]]

{{#ev:youtube|https://www.youtube.com/watch?v=My6oGvkHnfY|500|center}}

{{BR}}
== Apostrophes in Contractions ==

A [[Contraction|contraction]] combines words and leaves out one or more letters. Put the apostrophe where the missing letters belong.

{| class="wikitable"
! Full form
! Contraction
! Missing letters
|-
| do not
| don’t
| o
|-
| I am
| I’m
| a
|-
| they are
| they’re
| a
|-
| we will
| we’ll
| wi
|-
| cannot
| can’t
| no
|}

Read the contraction and the full form aloud. They should have the same basic meaning.

{{#ev:youtube|https://www.youtube.com/watch?v=q5sG_CkkAs8|500|center}}

{{BR}}
== Apostrophes for Singular Possession ==

To show that one person, animal, place, or thing owns or is connected with something, add '''’s''' to a singular noun.

'''the student’s notebook''' means the notebook of one student.

'''the fox’s den''' means the den of one fox.

'''Ava’s idea''' means the idea belongs to Ava.

{{BR}}
== Apostrophes for Plural Possession ==

For a plural noun that already ends in '''s''', add an apostrophe after the final '''s'''.

'''the students’ notebooks''' means notebooks belonging to more than one student.

'''the birds’ nests''' means nests belonging to more than one bird.

For an irregular plural that does not end in '''s''', add '''’s'''.

'''the children’s books'''

'''the mice’s food'''

{{#ev:youtube|https://www.youtube.com/watch?v=2M4EDrD3aBQ|500|center}}

{{BR}}
== Apostrophes Do Not Make Regular Plurals ==

Most plural nouns need an '''s''' but no apostrophe.

'''Correct plural:''' three pencils

'''Incorrect plural:''' three pencil’s

Ask yourself: Does the noun show ownership, or does it simply mean more than one? Use an apostrophe only for ownership in this situation.

{{BR}}
== Its and It’s ==

'''It’s''' is a contraction of '''it is''' or '''it has'''.

'''It’s raining''' means '''It is raining'''.

'''It’s been fun''' means '''It has been fun'''.

'''Its''' is a possessive determiner. It shows that something belongs to an animal, object, or idea.

'''The robot raised its arm.'''

Use the replacement test: If '''it is''' or '''it has''' works, write '''it’s'''. Otherwise, write '''its'''.

{{BR}}
== Whose and Who’s; Their, They’re, and There ==

'''Who’s''' means '''who is''' or '''who has'''. '''Whose''' asks about or shows possession.

'''Who’s at the door?'''

'''Whose jacket is this?'''

'''They’re''' means '''they are'''. '''Their''' shows possession. '''There''' refers to a place or introduces an idea.

'''They’re carrying their bags over there.'''

These word pairs sound alike, so test the meaning instead of trusting the sound.

{{BR}}
= A Proofreading Strategy =

Use this five-step check when you edit:

# Read one sentence at a time.
# Underline lists, introductions, joined clauses, direct address, and extra information.
# Circle contractions and words that show possession.
# Explain the job of every comma and apostrophe.
# Read the corrected sentence aloud and check its meaning.

A punctuation mark should earn its place. If you cannot name its job, look at the sentence again.

{{BR}}
== Mini Editing Example ==

'''Draft:''' After school Maya and Luis packed the teams equipment but they couldnt find its map.

'''Edited:''' After school, Maya and Luis packed the team’s equipment, but they couldn’t find its map.

'''Why:''' The first comma follows an introductory phrase. The second comma joins two independent clauses with '''but'''. The apostrophe in '''team’s''' shows singular possession. The apostrophe in '''couldn’t''' replaces the missing '''o'''. The word '''its''' has no apostrophe because it shows possession.

A { comma } separates items or parts of a sentence. A comma often follows an { introductory } element. Two independent clauses may be joined with a comma and a coordinating { conjunction }. A name used in direct address is separated by a { comma }. An { apostrophe } can show that letters are missing. A shortened form such as don’t is a { contraction }. A singular noun usually takes apostrophe s to show { possession }. A plural noun ending in s usually takes an apostrophe after the final { s }. The word it’s can be replaced by { it is }. A regular plural such as books needs no { apostrophe }.
