Step-by-step solution for: Colons Worksheets - 15 Worksheets Library
Let's solve the worksheet step by step. The task is to correct each sentence by adding a colon where needed.
A colon (:) is used in writing to:
- Introduce a list.
- Introduce an explanation or elaboration.
- Follow a salutation in a formal letter.
- Introduce a quote or statement.
We’ll go through each sentence and determine if a colon is needed.

✘ This sentence is awkward and unclear. It seems like it’s trying to say:
"I’ve seen this movie: that guy dies at the end."
But “that guy dies at the end” is not a complete thought. However, if we interpret it as introducing a summary of the movie, then a colon might help.
✔ Corrected:
I've seen this movie: that guy dies at the end.
> ✔️ The colon introduces a brief explanation of the movie.
---
This sentence has a list of items: peas, broccoli, milk, and cheese.
The phrase "I added to the grocery list" is followed by a list — so a colon should be used before the list.
✔ Corrected:
I added to the grocery list: peas, broccoli, milk, and cheese.
> ✔️ Colon introduces the list.
---
This sentence is missing punctuation. The second part ("my new bookcase") explains what "it" is.
So, use a colon to introduce the explanation.
✔ Corrected:
It's finally here: my new bookcase.
> ✔️ The colon shows that "my new bookcase" explains what "it" is.
---
This is two independent clauses joined without proper punctuation. But the second clause explains the reason for the first.
So, we can use a colon to show that the second part explains the first.
✔ Corrected:
Listen to that siren: there must be a fire somewhere.
> ✔️ The colon introduces the reason or explanation.
---
Again, this has a list after "a few things." So, we need a colon before the list.
✔ Corrected:
I'm still looking for a few things: paper, pens, and clips.
> ✔️ Colon introduces the list.
---
This sentence lists names after "who I invited." The colon helps introduce the list of people.
✔ Corrected:
Here's who I invited: Mary Cole and your sister Grace.
> ✔️ Colon introduces the list of invitees.
---
This sentence has a main idea: "I do everything myself," followed by a list of actions.
Use a colon to introduce the list.
✔ Corrected:
I do everything myself: I write, illustrate, and publish these books.
> ✔️ Colon introduces the explanation of what “everything” means.
---
This sentence has a list of houses: mine, my sister’s, and yours.
The phrase "three houses" is followed by the list — so a colon is needed.
✔ Corrected:
The tornado destroyed three houses: mine, my sister's, and yours.
> ✔️ Colon introduces the list.
---
This is a strong statement with emphasis. The second part explains the first.
Use a colon to introduce the explanation.
✔ Corrected:
Let me tell you again: I do not want any pizza!
> ✔️ Colon introduces the repeated message.
---
Two independent clauses. The second explains why the first is true.
So, use a colon to introduce the reason.
✔ Corrected:
I don't eat sweets: I just don't have a sweet tooth.
> ✔️ The colon introduces the explanation.
