Tracing Arguments & Evaluating Claims in a Text - 6th Grade Reading

SECTION 1

Why Does This Skill Matter?

Every day you're surrounded by people trying to convince you of something. Advertisements tell you that a certain sneaker will make you faster. News articles claim that a new law will help students. Your friend insists that one video game is better than another. But how do you know if any of these claims are actually true?

The skill of tracing and evaluating arguments (following an author's line of thinking step by step) is one of the most important things you can learn. It lets you figure out whether a writer is giving you solid reasons and evidence or just hoping you'll agree without thinking. People have been studying this skill for thousands of years!

~350 BCE • Ancient Greece

The philosopher Aristotle wrote a book called Rhetoric, teaching people how arguments are built using logic, emotions, and credibility. He believed that good arguments need evidence, not just smooth-sounding words.

1620 • The Scientific Revolution

Sir Francis Bacon promoted the idea that claims should be tested with evidence. He helped create the scientific method, which requires observations and data before anyone accepts a claim as true.

1947 • Media Literacy Begins

After World War II, educators realized that people needed to be taught how to evaluate arguments in newspapers, radio, and film. Schools started teaching students to separate fact from opinion.

2010 • Common Core Standards

The Common Core State Standards were adopted, making "tracing and evaluating arguments" a key reading skill for students in the United States. Standard RI.6.8 is the one you're learning right now!

So here's the big question this lesson will help you answer: When you read an informational text, how do you figure out which claims are supported by evidence and reasons — and which claims are not?

SECTION 2

Core Definitions You Need to Know

Before we can evaluate arguments, we need to learn the vocabulary. Think of these terms as your detective toolkit. Each one helps you break down what an author is saying and decide if it's trustworthy.

Argument

An argument is the author's overall case — the main point they want you to believe. It's like the "big picture" of what they're trying to prove.

Claim

A claim is a specific statement that the author says is true. An argument is usually made up of several smaller claims that fit together like puzzle pieces.

Reason

A reason is the "because" part — it explains why a claim might be true. Reasons connect the claim to evidence with logic.

Evidence

Evidence is the proof — facts, statistics, examples, quotes from experts, or research studies that back up a claim and make it believable.

Unsupported Claim

An unsupported claim is a statement that has no evidence or reasons behind it. It might sound convincing, but it's just an opinion dressed up to look like a fact.

✦

KEY TAKEAWAY

Think of an argument like building a house. The argument is the whole house. The claims are the walls. The reasons are the nails and screws holding the walls up. And the evidence is the strong foundation underground. A wall without nails or a foundation? It's going to fall down — just like a claim without reasons or evidence.

SECTION 3

Visual Guide: The Anatomy of an Argument

The diagram below shows you how an argument is structured. Notice how the main argument sits at the top, supported by claims. Some claims are connected to reasons and evidence — those are supported claims. Others are floating with nothing underneath them — those are unsupported claims.

When you read a text, your job is to be like a detective. You look at each claim and ask: "Did the author give me a good reason for this? Did they show me evidence?" If the answer is yes, the claim is strong. If not, you should be skeptical.

SECTION 4

The Step-by-Step Process

Here's how you actually trace and evaluate an argument when you're reading an informational text. Think of these as the four detective steps you follow every time.

STEP 1 — IDENTIFY THE ARGUMENT

Ask: "What is the author trying to convince me of?"

This is usually found in the introduction or thesis statement. It's the big idea.

STEP 2 — FIND THE CLAIMS

Ask: "What specific statements does the author make?"

Look at each paragraph. Claims are often the first or last sentence of a paragraph.

STEP 3 — CHECK FOR SUPPORT

Ask: "Does the author give reasons and evidence for each claim?"

Evidence includes facts, statistics, expert quotes, and real examples. Reasons explain the logic.

STEP 4 — EVALUATE

Ask: "Is this argument convincing? Are there weak spots?"

A strong argument has supported claims. An argument with unsupported claims has weak spots you can question.

Let's see what this looks like with a real passage. Notice how each step helps you become a smarter reader. In the next section, we'll break down the different types of evidence you might find (or not find!) in a text.

SECTION 5

Types of Evidence & How to Spot Them

Not all evidence is the same. Some types of evidence are very strong, while others are weaker. Here's a guide to the types of evidence you might find in informational texts — and how to judge their strength.

Type of Evidence	Strength	Example
Statistics / Data	Very strong	"A 2023 study found that 82% of teens get less than 8 hours of sleep."
Expert Quotes	Strong	"Dr. Patel, a sleep scientist, explains that teens need 9 hours of rest."
Real-World Examples	Moderate	"At Jefferson Middle School, later start times led to fewer students falling asleep in class."
Personal Opinions	Weak	"Most people agree that kids should sleep more." (No data or source)
No Evidence	None	"Schools should obviously start later." (Nothing to support it)

✦

KEY TAKEAWAY

Imagine you're a judge in a courtroom. A lawyer can't just say, "My client is innocent!" and sit down. They need to show proof — witnesses, video, documents. The same goes for authors. When they make a claim, you should expect them to show their proof. If they don't, that claim is unsupported, and you should be cautious about believing it.

SECTION 6

Worked Example: Tracing an Argument

Let's practice with a short passage. Read it carefully, then follow along as we trace and evaluate each claim step by step.

📝

SAMPLE PASSAGE:

"Schools should replace homework with more reading time. (A) Research from the National Education Association shows that students who read for 20 minutes a day score 90% higher on vocabulary tests. (B) Furthermore, homework causes too much stress for kids. (C) A 2022 survey by the American Psychological Association found that 45% of teens say homework is their biggest source of stress. (D) Everyone knows that students would be happier without homework. (E)"

Tracing an Argument Step by Step

1
Step 1 — Identify the Main Argument

The author's main argument is: "Schools should replace homework with more reading time." This is the big idea they want us to believe. Everything else in the passage should support this argument.
2
Step 2 — Find Each Claim

Let's break the passage down into individual claims: Claim A: Students who read 20 minutes a day score 90% higher on vocabulary tests. Claim B: Homework causes too much stress for kids. Claim C: 45% of teens say homework is their biggest source of stress. Claim D: Everyone knows that students would be happier without homework.
3
Step 3 — Check for Reasons and Evidence

Claim A — SUPPORTED ✓ The author cites the National Education Association and gives a specific statistic (90% higher). This is strong evidence from a credible source. Claim B — PARTIALLY SUPPORTED This claim is a reason (homework causes stress), and it is supported by Claim C. So Claims B and C work together. Claim C — SUPPORTED ✓ The author cites a 2022 survey by the American Psychological Association with a specific statistic (45%). This is real evidence! Claim D — UNSUPPORTED ✗ "Everyone knows" is not evidence — it's just a vague appeal. The author gives no data, no expert quote, and no example. This is an unsupported claim.
4
Step 4 — Evaluate the Argument

Overall, this argument is mostly strong. Two claims are backed by specific evidence from credible sources. However, Claim D is a weak spot because it uses the phrase "everyone knows" without any proof. A critical reader would notice this and not be fully convinced by that part of the argument.

SECTION 7

Strong Arguments vs. Weak Arguments

Now that you know how to trace and evaluate claims, let's compare what makes an argument strong versus what makes it weak. This will help you quickly spot the difference when you're reading on your own.

Feature	Strong Argument	Weak Argument
Claims	Clear, specific claims that connect to the main argument	Vague or overly broad claims that are hard to prove
Evidence	Uses statistics, expert quotes, or real examples	Uses no evidence, or only personal opinions
Reasons	Explains why the evidence supports the claim	Jumps from claim to claim without explaining the logic
Language Clues	"According to…", "Research shows…", "A study found…"	"Everyone knows…", "Obviously…", "It's clear that…"
Overall Effect	You feel convinced because the proof is right there	You feel unsure because you're just asked to trust the author

✦

KEY TAKEAWAY

Think of it like this: a strong argument is like a bridge built with steel beams (evidence) and bolts (reasons). You can walk across it safely because you can see what's holding it up. A weak argument is like a bridge made of cardboard — it looks like it might work, but there's nothing solid underneath. Your job as a reader is to test the bridge before you walk across!

SECTION 8

Where Does This Skill Lead?

The skill you're learning right now — tracing and evaluating arguments — is the foundation for something called critical thinking. As you move through school, you'll use this skill in bigger and more complex ways.

What You're Learning Now (6th Grade)	What Comes Next (7th–8th Grade & Beyond)
Identify whether a claim is supported or unsupported	Evaluate whether the evidence is relevant (does it actually connect?) and sufficient (is there enough?)
Find evidence like facts, statistics, and expert quotes	Analyze bias — does the author have a reason to leave out certain evidence?
Trace one author's argument	Compare arguments from multiple authors on the same topic and decide which is more convincing
Spot vague language like "everyone knows"	Identify logical fallacies (tricks in reasoning) like false cause, straw man, and bandwagon appeals

In 7th and 8th grade, you'll also start writing your own arguments in essays. The same rules apply to your own writing! When you make a claim, you'll need to back it up with evidence and reasons — just like the authors you're learning to evaluate now. Think of this lesson as training to become both a smarter reader and a stronger writer.

SECTION 9

Practice Problems

Time to put your skills to the test! Try each problem before clicking "Show Answer." The problems start easy and get more challenging.

Question 1: PROBLEM 1 — CONCEPTUAL

What is the difference between a claim and evidence?

Show answer

A claim is a statement that the author says is true — it's what they want you to believe. Evidence is the proof that supports the claim, like facts, statistics, expert quotes, or real-world examples. Think of the claim as the "what" and the evidence as the "why you should believe it." Without evidence, a claim is just an opinion. Nice work if you got this — it's the most important definition in this whole lesson!

Question 2: PROBLEM 2 — IDENTIFICATION

Read this sentence: "According to the Centers for Disease Control, only 1 in 4 children gets 60 minutes of physical activity each day." Is this a supported claim or an unsupported claim? How do you know?

Show answer

This is a supported claim. Here's how we know: the author names a specific, credible source (the Centers for Disease Control) and provides a specific statistic ("only 1 in 4 children"). The phrase "According to" is a signal that evidence is being given. This is exactly the kind of support that makes a claim trustworthy!

Question 3: PROBLEM 3 — INTERMEDIATE

Read this short passage: "Students should be allowed to use phones during lunch. Phones help students stay connected with their parents in case of emergencies. Besides, nobody wants to just sit there with nothing to do." Identify the main argument and each claim. Which claims are supported and which are unsupported?

Show answer

Main argument: Students should be allowed to use phones during lunch. Claim 1: "Phones help students stay connected with their parents in case of emergencies." — This is a partially supported claim. The author gives a reason (emergency contact), which makes logical sense, but doesn't provide evidence like a study or a real example. Claim 2: "Nobody wants to just sit there with nothing to do." — This is an unsupported claim. "Nobody wants to" is vague language with no proof. The author doesn't cite any survey or data. Maybe some students enjoy chatting with friends without their phones! This claim is weak because it assumes something without backing it up.

Question 4: PROBLEM 4 — APPLIED

Your school newsletter publishes this article: "Our school should switch to a four-day school week. A study by the University of Montana found that schools on four-day weeks saw a 20% drop in absences. Teachers at the pilot schools reported feeling less burnt out. Of course, every student would love a three-day weekend." Trace the argument. List each claim, label it as supported or unsupported, and explain your reasoning for each one.

Show answer

Main argument: Our school should switch to a four-day school week. Claim 1: "Schools on four-day weeks saw a 20% drop in absences." — Supported ✓. The author cites the University of Montana and gives a specific statistic (20%). This is strong evidence. Claim 2: "Teachers at the pilot schools reported feeling less burnt out." — Partially supported. The author mentions "pilot schools" and teacher reports, which sounds like evidence, but doesn't name a specific study or give numbers. It's better than nothing, but could be stronger. Claim 3: "Every student would love a three-day weekend." — Unsupported ✗. The word "every" is a red flag — the author can't know what every student wants without a survey. This is an opinion without proof. Great job if you caught all three!

Question 5: PROBLEM 5 — CRITICAL THINKING

Imagine you are writing a letter to your principal arguing that your school should start a recycling program. Write two claims: one that is supported with evidence and one that is unsupported. Then explain why one is stronger than the other.

Show answer

Here's one possible answer (yours might be different, and that's okay!): Supported claim: "According to the Environmental Protection Agency, recycling one ton of paper saves 17 trees and 7,000 gallons of water. Starting a recycling program would help our school reduce waste and protect the environment." — This is strong because it names a credible source (EPA) and uses specific numbers. Unsupported claim: "Everyone would participate in the recycling program because it's the right thing to do." — This is weak because "everyone" is too vague, and "the right thing to do" is an opinion, not a fact. The first claim is stronger because it uses real evidence from a trusted source. A reader (like your principal) would be more likely to be convinced by specific facts than by a vague opinion. This is why supported claims make arguments powerful! You're thinking like a real writer now — awesome work!

SUMMARY

Putting It All Together

Summary

When you read an informational text, your job is to think like a detective. An argument is the author's overall point — what they want you to believe. That argument is built from claims, which are specific statements the author says are true. A supported claim is backed up by evidence (facts, statistics, expert quotes, or real examples) and reasons (logical explanations connecting the evidence to the claim). An unsupported claim has no evidence or reasons behind it — it's just an opinion pretending to be a fact.

To evaluate an argument, follow four steps: first, identify the main argument; second, find each claim; third, check whether each claim has evidence and reasons; and fourth, judge the overall strength of the argument. Watch out for red-flag phrases like "everyone knows" or "obviously" — these often signal an unsupported claim. The strongest evidence comes from statistics and expert sources, while the weakest "evidence" is really just the author's personal opinion. By mastering this skill, you become a critical reader who can't be fooled by smooth-sounding words without solid proof behind them.
