Quick answer: Use “like” when comparing nouns directly (“She runs like the wind”) and “as” when introducing a clause with a verb (“She runs as if she’s being chased”). Both create similes, but they follow different grammatical rules that every 5th grader needs to master.
Students constantly mix up “like” and “as” when writing similes on their worksheets. This confusion shows up in everything from classroom assignments to standardized tests, and it’s one of the most common errors I see when reviewing 5th grade writing. Let’s clear this up once and for all.
| Term | Meaning / When to use | Example sentence |
|---|---|---|
| Like | Use to compare two nouns or pronouns directly; followed by a noun, pronoun, or noun phrase | “The clouds looked like cotton candy.” |
| As | Use when introducing a clause that contains a subject and verb; often appears as “as if” or “as though” | “The clouds swirled as if they were alive.” |
When to use Like
The word “like” is your go-to choice when you’re making a direct comparison between two things. “like” should be followed by a noun or pronoun, never a full clause with a verb. This is the simpler of the two structures, which is why it appears first in most worksheet on similes for grade 5 materials.
Here’s how it works in practice:
- “My brother eats like a horse.” (comparing “brother” to “horse”)
- “That car sounds like a jet engine.” (comparing “car” to “jet engine”)
- “She sings like an angel.” (comparing “she” to “angel”)
I see this error constantly in student writing: “She looks like she’s tired” when it should be “She looks as if she’s tired.” The word “like” cannot introduce a clause with its own subject and verb. On a worksheet on similes for grade 5, you’ll typically see “like” used for straightforward noun-to-noun comparisons because it’s more accessible for students just learning figurative language.
Real-world examples from actual student work:
Email to teacher: “My dog acts like he knows tricks” (INCORRECT – has subject “he” and verb “knows”)
Fixed version: “My dog acts as if he knows tricks” (CORRECT)
Resume-style homework assignment: “Works like a team player” (CORRECT – comparing to noun “team player”)
Text message to friend: “You’re acting like a baby” (CORRECT – comparing “you” to “baby”)
When to use As
The word “as” (or the phrases “as if” and “as though”) is required when your comparison includes a subject and a verb—what grammarians call a clause. This is where students get tripped up on their worksheet on similes for grade 5 assignments. The structure is slightly more complex, but it’s essential for creating sophisticated comparisons.
Use “as” in these situations:
- “He acted as if he hadn’t heard the question.” (clause: “he hadn’t heard”)
- “The water felt as cold as ice.” (comparing degree/extent)
- “She danced as though she was floating.” (clause: “she was floating”)
The phrase “as if” or “as though” signals that what follows is hypothetical or imagined, which is perfect for similes. According to the Wikipedia article on Simile, this figure of speech explicitly compares two different things using “like” or “as,” and understanding when to use each conjunction is fundamental to mastering the technique.
Common examples that appear on grade 5 assessments:
- “The old house creaked as if it was alive.”
- “He ran as though his life depended on it.”
- “The cookies smell as good as Grandma’s.”
Real-world examples I’ve corrected in student papers:
Cover letter for school newspaper: “I work hard like I care about grades” (INCORRECT – has subject “I” and verb “care”)
Fixed version: “I work hard as if I care about grades” (CORRECT)
Wedding toast practice (yes, 5th graders write these for family!): “They love each other like they’re soulmates” (INCORRECT)
Fixed version: “They love each other as if they’re soulmates” (CORRECT)
LinkedIn bio (for that entrepreneurial kid): “I think like I’m the boss” (INCORRECT)
Fixed version: “I think as if I’m the boss” (CORRECT)
How to remember the difference
Here’s the memory trick I’ve used with hundreds of 5th grade students: Like = Noun, As = Action.
If what comes after your comparison word is just a thing (a noun), use LIKE. If what comes after has an action word (a verb), use AS.
Another way to think about it: “Like” is shorter and simpler, just like a noun. “As” often appears in the longer phrases “as if” or “as though,” which give you room for a full clause with a verb.
Try this test: After you write your simile, look at the word immediately following “like” or “as.” Can you replace it with a simple noun? If yes, “like” is probably correct. Does it have a subject doing something? Then you need “as if” or “as though.” For more, see Worksheet.
For example:
- “She looks like [a movie star]” ← “movie star” is a noun ✓
- “She looks as if [she’s a movie star]” ← “she’s” has a subject and verb ✓
This simple check catches about 90% of the errors I see on worksheet on similes for grade 5 assignments.
Common mistakes and exceptions
The most frequent mistake students make is using “like” when they should use “as if” or “as though.” This error is so common that it’s become acceptable in casual conversation, but it’s still marked wrong on tests and worksheets. When a student writes “It looks like it’s going to rain,” a strict grammarian will correct it to “It looks as if it’s going to rain.”
Another common error appears in comparative structures with “as…as.” Students sometimes write “She’s as tall like her brother” when it should be “She’s as tall as her brother.” The “as…as” construction is used for equal comparisons and doesn’t follow the same rules as simile “like/as.”
Regional differences matter here too. In informal American English, you’ll frequently hear “like” used where traditional grammar demands “as if.” However, on a worksheet on similes for grade 5, students are expected to use formal, standard English. The same applies to UK English, where the rules are identical despite different spelling conventions for other words.
One genuine exception: When “like” functions as a preposition meaning “similar to” or “characteristic of,” it’s always correct. For example, “Like her mother, she has blue eyes” is perfectly fine because “like” isn’t creating a simile here—it’s functioning as a preposition.
I’ve seen this mistake repeatedly in real student work:
Book report: “The character acts like he’s brave” (INCORRECT in formal writing)
Fixed version: “The character acts as if he’s brave” (CORRECT)
Science lab conclusion: “The liquid bubbled like it was boiling” (INCORRECT)
Fixed version: “The liquid bubbled as if it was boiling” (CORRECT)
Persuasive essay: “We should recycle like our future depends on it” (INCORRECT)
Fixed version: “We should recycle as if our future depends on it” (CORRECT)
Frequently Asked Questions
Can I use “like” and “as” interchangeably in similes?
No, they follow different grammatical rules. Use “like” before nouns and pronouns, and “as” (or “as if/as though”) before clauses with subjects and verbs. Mixing them up will cost you points on grammar assessments.
Why do worksheets focus so much on “like” vs “as” for 5th graders?
Because 5th grade is when students transition from basic writing to more sophisticated figurative language. Mastering the difference between “like” and “as” shows understanding of clause structure and prepares students for middle school writing expectations.
Is it wrong to say “like” in everyday conversation?
In casual speech, using “like” instead of “as if” is extremely common and generally accepted. However, formal writing, school assignments, and standardized tests require the grammatically correct form. Know your audience.
What if I’m comparing two actions instead of two things?
When comparing actions, you typically need “as” or “as if/as though” because you’re dealing with clauses. For example: “She sings as her mother did” (comparing the action of singing), not “She sings like her mother did.”
