Week 10 — The Fact-Check Sprint
Verification & Debugging — Part 2 (Key Activity)
This is the key activity week for Unit 3. Students learn lateral reading — the technique that professional fact-checkers use. Instead of spending a long time reading one source and deciding if it's trustworthy, you open new tabs and see what OTHER sources say about it. Then students run a "Fact-Check Sprint": given a claim, they race to trace it back to its origin and determine whether it holds up.
Key Vocabulary
| Term | Definition |
|---|---|
| Lateral reading | A verification technique where you leave the page and check what other sources say, instead of reading one source deeply |
| Vertical reading | Reading one source carefully from top to bottom — less reliable than lateral reading for judging accuracy |
| Fact-check | The process of investigating a specific claim to determine whether it's true, false, or misleading |
| Three-Tab Rule | A rule of thumb: find the claim confirmed by at least three different, unrelated sources before believing it |
| Coverage | How a news outlet reports on an event — including what they include, what they leave out, who they interview, and what tone they use |
| Sourcing | The practice of identifying and citing where information came from — who the reporter talked to, what documents they used |
Last week you got your first checking tools. This week, you become a speed-checker! You'll trace claims back to where they started, just like following footprints. The goal isn't to prove everything wrong — it's to figure out what you actually know and what you still need to check.
Connection
Last week students got their basic verification toolkit (source, date, search) and learned to distinguish between news reporting and opinion. This week is the Unit 3 key activity: they learn lateral reading — the actual technique professional fact-checkers use — and apply it in a timed Fact-Check Sprint. They also compare how different sources cover the same story to see construction choices in action. Next week they extend verification to visual media: photos, screenshots, and video clips.
From Week 9: Students learned three verification tools. This week they practice using all three in combination — checking source, date, AND other sources together — because no single check is enough on its own.
From Week 2: Remember "Who made this and why?" — that question is now essential for evaluating whether a source is trying to inform you or persuade you.
Teacher Preparation
Prepare 3–4 claims for the Fact-Check Sprint. Each should be something the student can investigate with a web search. Good types:
- A viral "did you know?" claim (e.g., "goldfish have a 3-second memory" — false)
- A misattributed quote (a quote credited to the wrong person)
- A real statistic taken out of context
- A photo used to illustrate the wrong story
Also prepare 2 news articles about the same event from different outlets. Choose a non-controversial, kid-friendly story (weather event, science discovery, animal rescue, community event). Print them or have them ready in side-by-side tabs. This will be used for the Source Comparison activity.
For Session 1, also prepare a brief demonstration of lateral reading: have a web browser open, and show how to open multiple tabs to compare what different sources say about the same topic.
Important: test your claims in advance. Make sure the student can find relevant results with a basic search.
Search for 'viral facts that aren't true' and pick 2-3 examples. Misattributed quotes and 'did you know?' posts work great. Print or write them on cards. If you have no printer, just read them aloud.
The Fact-Check Sprint should feel exciting, not like homework. Frame it as detective work: "You're an investigator. Your job is to find the truth before the clock runs out." Celebrate the process of investigating, not just getting the "right answer."
Guided Session 1
Lateral Reading
Learning Goal
Students can explain the difference between "vertical reading" (reading one source deeply) and "lateral reading" (checking what other sources say) and practice using lateral reading to assess a claim.
Activities
-
Two Ways to Read — Explain the difference:
- Vertical reading: You stay on one page. You read the whole article carefully. You look at the design of the website. You try to decide: "Is this trustworthy?"
- Lateral reading: You leave the page almost immediately. You open a new tab and search for what OTHER sources say about the same topic. You compare.
The surprise: professional fact-checkers almost never use vertical reading. They use lateral reading. It's faster and more reliable, because a single source can fool you — but it's very hard to fool five sources at once.
-
Live Demonstration — Open a browser. Show a claim (one of your prepared examples). Instead of reading the article carefully, copy the claim, open a new tab, paste it into a search engine, and see what comes up. Narrate your thinking aloud: "I see that three other news sites reported the same thing... this fact-checking site says it's confirmed... so it seems reliable." Or: "Hmm, nobody else is reporting this. The only source is this one blog. That's a warning sign."
-
Student Practice — Give the student a claim and let them try lateral reading themselves. Guide them through the process:
- Copy the main claim
- Search for it
- Open 2–3 results from different sources
- Compare: do they say the same thing?
- Verdict: reliable, uncertain, or unreliable?
-
The Three-Tab Rule — Give the student a simple rule of thumb: "Before you believe a claim, try to find it confirmed by at least three different, unrelated sources. If only one source says it, slow down. If three say it, it's more likely true."
Reflection Questions
- Why is checking other sources better than reading one source very carefully?
- Was lateral reading faster or slower than you expected?
- Can you think of a time when you could have used the Three-Tab Rule?
Guided Session 2
The Fact-Check Sprint
Learning Goal
Students can take a specific claim, trace it back toward its original source, and make an evidence-based judgment about its accuracy.
Activities
-
Set the Stage — Explain the rules: "I'm going to give you a claim. Your job is to figure out if it's true, false, or misleading. You have 10 minutes. Use lateral reading. Find as much evidence as you can."
-
Sprint Round 1 — Present the first claim. Start a timer. The student searches, reads, compares sources, and reaches a verdict. When time is up (or they finish early), discuss:
- What did you find?
- How many sources did you check?
- Do they agree?
- What's your verdict?
- How confident are you? (Scale of 1–10)
-
Sprint Round 2 — Present a second claim. This one should be trickier — perhaps a true statistic presented in a misleading way, or a real event described with wrong details. Repeat the process.
-
Sprint Round 3 (optional, if time allows) — Present a third claim. Try to make each round progressively more challenging.
-
Debrief — Review all the claims. Reveal the actual truth behind each one. Ask: "Which one was hardest? What made it tricky? What would have happened if you had just believed it without checking?"
-
Source Comparison: Same Story, Different Choices — Present the two news articles about the same event. Read key sections together and compare using a simple chart:
Question Source A Source B What's the headline? Who is quoted or interviewed? What facts are included? What's the overall tone? What's left out or barely mentioned? The most important column is the last one. "Every story has to leave things out — you can't include everything. But what gets left out changes the story you end up telling." Ask: "Could someone read only one of these and get a misleading impression? Does reading both give you a fuller picture?"
Important nuance: Differences between sources don't automatically mean one is wrong or biased. Coverage choices are often driven by space, audience, or emphasis — not deception. The skill is noticing the differences and using them to build a more complete picture, not jumping to accusations of bias.
-
Media Checkpoint Connection — Link to The Media Checkpoint. Question 6 (What am I missing?) is the star this week. Lateral reading and source comparison are how you answer that question. When you read only one source, you're trusting one set of construction choices. When you compare, you find what each source left out.
Keep using the five-step process from Week 9: Stop → Notice → Check → Compare → Decide. This week, the Compare step gets a major upgrade — lateral reading and source comparison are how you do it well.
Reflection Questions
- How did it feel to investigate something yourself instead of just trusting what someone told you?
- Did any of the claims surprise you?
- How long did it take to check something? Is that effort worth it?
Independent Session
Fact-Check Report
Instruction
Choose one claim to investigate deeply on your own. It can be:
- Something you saw online recently
- A "fact" a friend told you
- Something from the Fact-Check Sprint that you want to dig into further
- A claim the adult provides for you
Write a Fact-Check Report with these sections:
- The Claim: What is the claim, exactly? Write it out word for word.
- The Source: Where did this claim come from? Who said it first?
- The Search: What did you find when you searched for it? List 2–3 other sources and what they said.
- The Verdict: True, false, misleading, or uncertain?
- The Evidence: In 2–3 sentences, explain why you reached your verdict.
If you want a challenge, present your report to someone in your family and see if they believed the claim before you investigated it.
Skills Reinforced
- Independent investigation using lateral reading
- Structuring findings into a clear, organized report
- Building confidence in personal verification ability
Setup
Provide a device with a web browser (supervised), a notebook or report template, and a quiet workspace. Pre-approve the claim if the student needs one. Set a timer for 25 minutes — 15 for research, 10 for writing.
Quick Check
After this week's sessions, the student should be able to:
- Explain lateral reading: Describe the difference between vertical and lateral reading and why lateral reading is more reliable.
- Apply the Three-Tab Rule: Given any claim, open multiple tabs and check what different sources say.
- Write a verdict: Produce a one-sentence evidence-based judgment about a claim's accuracy.
- Compare coverage: Describe specific differences between two outlets' coverage of the same event and explain what each source left out.
Caregiver Look-Fors
- The student naturally opens new tabs to check claims instead of trusting one source
- They can narrate their thinking: "This source says X, but this other one says Y..."
- They enjoy the detective-work feel of the Fact-Check Sprint
- They are building confidence in their own ability to investigate
- They show appropriate nuance ("uncertain" is a valid verdict)
🎯 Takeaway
Big idea: Tracing a claim back to its original source is one of the most powerful things you can do to evaluate information.
Remember: The further a claim travels from its original source, the more it can change. Go back to the beginning when you can.
Younger Learner Adaptation (Ages 6–8)
- Adult-guided lateral reading: The adult handles the browser while the student makes decisions ("Should we trust this? Let's check another tab.").
- Two-Tab Rule: Simplify from three to two confirming sources.
- Visual comparison: Print search results from two sources and physically place them side by side.
- Skip the formal report: Replace the written Fact-Check Report with a verbal presentation to a family member.
Older Learner Extension (Ages 11–13)
- Source quality ranking: After lateral reading, rank the sources by reliability and explain why some are more trustworthy than others.
- Three-source comparison: Add a third outlet to the source comparison and track how coverage varies even more across three accounts of the same event.
- Investigate a current claim: Choose a claim currently circulating on social media and write a real fact-check report.
- Debrief on speed vs. depth: When is a quick check sufficient? When do you need to dig deeper? Develop personal guidelines.
Accessibility Options
- Verbal fact-check: The student narrates their investigation process while the adult takes notes.
- Pre-opened tabs: Set up the browser with tabs already open so the student focuses on comparing, not navigating.
- Paired sprint: Run the sprint together — the student directs, the adult types and clicks.
- Audio report: Record the Fact-Check Report as a voice memo instead of writing it.
- Graphic organizer: Use a three-column chart (Source 1 / Source 2 / Source 3) for easy comparison.
