Your First Digital Footprint
A new student left tracks all over the internet. Use the clues to solve four locks and clean up the trail.
The premise
Every time you go online, you leave marks. We call these marks a digital footprint. Read the clues, then open all four locks. Each lock has a reason that shows why the answer is right.
How this breakout builds CLEAR thinking
Every Critical Thinking Online Breakout runs on the CLEAR process — Claim, Lens, Evidence, Alternatives, Response (full framework). Here is where students practice each step in this activity:
- Claim — for each lock, decide what answer it is really asking for, and make it specific.
- Lens — notice what you already assume before you choose.
- Evidence — weigh the six clues; “Class Pet” is true but off-topic, so it is not evidence for any lock.
- Alternatives — the multiple-choice and multi-select locks force a comparison of competing options.
- Response — the reason revealed after each lock models the justified answer to act on.
Standards alignment
Aligned to Texas TEKS Technology Applications, Grade 3, §126.8, Digital Citizenship strand — subsections (c)(10), (c)(8), (c)(9). Skills are paraphrased; read the official standard at tea.texas.gov. This page shows the reasoning focus of each lock — not the answers.

In the classroom
- Warm up (5 min). Ask: “Be a Footprint Detective” — what does this mean online? Surface prior experience before the activity.
- Model one clue. Open a single clue together and think aloud: what does this tell us, and which lock might it help?
- Reason, don’t guess. Require students to say why before checking a lock. After each solve, read the revealed reason and compare it to their thinking.
- Spot the decoy. One clue is true but useless. Debrief which one and how they knew — a core evaluation skill.
- Language support. The 🌐 picker offers 7 languages; pair newcomers to discuss clues in their home language, then answer.
- Extend. Have students write a new clue, or a real-life example, for the focus skill they found hardest.
Answers are intentionally not shown here. The full answer key (with the reasoning for every lock) is on the password-gated answer-key page. This alignment is a good-faith paraphrase for lesson planning and is not legal advice.
