🔑 KEY CONCEPT: Complete Sentence
A complete sentence is a group of words that expresses a full thought and can stand alone.
A complete sentence needs:
✓ A subject (who or what the sentence is about)
✓ A predicate (tells what the subject does or is)
✓ A complete thought (makes sense by itself)
✓ End punctuation (. ! ?)
Let's look closer at what makes a sentence complete!
Each part has an important job.
Example: "Fae watched TikTok for three hours."
Subject: Fae (who the sentence is about)
Predicate: watched TikTok for three hours (what she did)
Complete thought: ✓ We understand the whole idea!
Why does this matter?
When you understand what makes ONE complete sentence, you can spot when TWO complete sentences are incorrectly smooshed together!
🔑 KEY CONCEPT: Run-On Sentence
A run-on sentence is when two or more complete sentences are joined together WITHOUT any punctuation or connecting word between them.
Why "run-on"?
Because the sentence just keeps running and running without stopping properly—like it's running on and on and on! 🏃💨
Example of a Run-On:
❌ Run-On Sentence:
Jenson got cooked in Fortnite he rage quit the game
Why is this a problem?
Without punctuation, readers can't tell where one idea ends and the next begins. It's confusing and hard to read!
🔑 WATCH OUT!
Some words LOOK like they connect sentences, but they don't work like punctuation!
Words That DON'T Fix Run-Ons:
These words can't save you from a run-on:
• then
• there
• now
• here
❌ Still a Run-On:
Aaliyah finished her homework then she played Roblox
❌ Still a Run-On:
Shoni had a great idea now everyone wants to try it
Why doesn't "then" fix it?
"Then" is just a regular word—it's not punctuation and it's not a connecting word (conjunction). You still have two complete sentences with nothing properly joining them!
🔑 KEY CONCEPT: Comma Splice
A comma splice is when two complete sentences are joined with ONLY a comma (no connecting word).
What's a "splice"?Splice means to join two things together. In this case, you're trying to splice (join) two sentences with just a comma—and that's not enough!
Example of a Comma Splice:
❌ Comma Splice:
Ishani is 6-7 at basketball, she makes almost every shot
Why is this a problem?
A comma is too weak to hold two complete sentences together. It's like using a piece of tape to hold up a heavy picture—you need something stronger!
Cobie's art is amazing, everyone says she should be a professional artist
❌ Comma Splice:
Teyanna got a new phone, it's way better than her old one
❌ Comma Splice:
That movie was bussin, we should watch it again
💡 The Pattern:
See how each sentence has TWO complete thoughts with only a comma between them? That comma needs help from a connecting word—or it needs to be replaced with stronger punctuation!
🔑 Strategy #2: Use a Comma + FANBOYS
Add a comma followed by a coordinating conjunction (a connecting word from FANBOYS).
2Comma + Connecting Word
The comma + FANBOYS combo is perfect for connecting related ideas!
Remember FANBOYS—The Seven Connecting Words:
F A N B O Y S
For • And • Nor • But • Or • Yet • So
What's a "coordinating conjunction"?
That's the fancy grammar term for FANBOYS words. They coordinate (connect) two equal ideas. Don't worry—you just need to remember FANBOYS!
🔑 Strategy #3: Use a Semicolon
Use a semicolon (;) to connect two complete sentences that are VERY closely related.
3The Semicolon (Advanced Move!)
Think of the semicolon as a "super comma"—stronger than a comma, but not as final as a period.
❌ BEFORE (Run-On):
Liam's soccer team won the championship they celebrated all weekend
✓ AFTER (Fixed!):
Liam's soccer team won the championship; they celebrated all weekend.
What's a semicolon?
It's this punctuation mark: ;
It's like a period and comma had a baby! It's stronger than a comma but shows the ideas are closely connected.
⚠️ Important:
Semicolons are powerful, but use them SPARINGLY in 5th grade writing! Strategy #1 and #2 are usually better choices.
Use a semicolon when:
• The two ideas are SUPER closely related
• They feel like two parts of one big thought
• You want to sound sophisticated
• But remember: don't overuse them!
Good Example:
✓ Good use of semicolon:
Jenson loves video games; he plays them every single day.
Why it works: These ideas are about the same topic and very closely connected.
Pro Tip:
When in doubt, use Strategy #1 (period) or Strategy #2 (comma + FANBOYS) instead. Those are always safe choices!
Your Challenge:
Look back through your recent writing (your energy article, any stories, or other assignments) and find 2-3 run-on sentences or comma splices. Use the strategies you learned today to fix them!
Steps to Complete This Task:
Read through your writing carefully—out loud helps!
Look for long sentences that might be two thoughts smooshed together
Check for commas that are trying to do too much work without a FANBOYS word
Choose the best fix-it strategy for each sentence
Rewrite the sentence with proper punctuation
Remember:
Even professional writers have run-ons and comma splices in their first drafts! Fixing them is part of revision—it makes your writing clearer and easier to read. You've got this! 💪
