Everything is ready: teams are formed, the timer is running, and the scoreboard is on the projector. But one thing often gets overlooked — how do students actually get to these pages on their own devices? Reading a URL aloud or having students type it in can eat up several minutes. A QR Code and a short link are two tools that solve this in under 30 seconds.
1. Two Sharing Scenarios, Two Solutions
Sharing a tool link with students typically falls into one of two situations:
| Situation | Description | Recommended Tool |
|---|---|---|
| In-person class — students scan with a phone | Project the QR Code on screen; students scan and connect instantly | QR Code Generator |
| Online class or sending a message | Drop a short, memorable link into a chat or messaging group | Short Link |
Neither method requires students to type a full URL. The difference is delivery: one uses a scan, the other uses a paste.
2. QR Code Generator: Project It, Scan It, Done
The QR Code Generator converts any URL into a scannable image. Project it on the classroom display and students point their phone camera at it — no typing needed, the page opens directly.
Key features:
- Paste any URL and get a QR Code instantly
- Adjustable size to ensure the code stays crisp when projected
- Download as PNG to drop into a slide deck or print as a handout
- No sign-up required
3. Short Link: Easy to Share, Easy to Type
The Short Link tool compresses a long URL into a brief, custom alias. For online classes or any situation where you're dropping a link in a chat, a short link is more practical than a QR Code: students can click it directly or type it from memory.
Key features:
- Custom alias so the link is easy to remember (e.g.
gui.tw/s/quiz1) - Set an expiry date to keep old links from causing confusion
- Track click counts to confirm students have connected
- Reuse the same link — just update the destination URL for the next activity
class-timer means students can type it themselves next time, without waiting for you to post it again.
4. QR Code vs. Short Link: Which One?
| Factor | QR Code | Short Link |
|---|---|---|
| How students connect | Scan with a phone camera | Click or type the short URL |
| Best for | In-person class, projected display | Online class, chat or messaging |
| Students need | A phone with a camera | Any internet-connected device |
| Setup speed | Instant — paste URL, get code | ~1 min to choose a custom alias |
| Reusable | Regenerate each time | Update destination, keep the same link |
Quick rule: Have a screen to project? Use a QR Code. Sharing in a chat? Use a short link. You can also do both: turn the short link into a QR Code, so it works whether students scan or type.
5. The Complete Paperless Workflow (With the Sharing Step)
Add the sharing step and the full classroom activity flow looks like this:
- Set up tools: Open the Lucky Wheel, Stopwatch, and Counter pages, then copy each URL.
- Make QR Codes: Paste each URL into the QR Code Generator; save the images into the corresponding slides.
- Form teams: Use the List Grouping tool to randomly assign students to teams; project or share the result.
- Connect students: Switch to the QR Code slide — students scan and land on the timer or scoring page.
- Run the activity: Use the wheel to cold-call, the stopwatch to keep time, and the counter to track scores — all controlled from the teacher's screen.
- Final reveal: Switch the Scoreboard to full-screen and project the final result.
Adding the QR Code step turns the tools from a teacher-only display into something the whole class participates in.
6. Summary
Sharing a link might seem trivial, but it's one of the most common places where "the teacher is ready but the students aren't there yet." QR Codes work best for one-time scans in an in-person setting; short links work best for online classes and links that get reused across sessions. Both cut down the time students spend just trying to get connected, keeping the activity moving from the first second. Every tool covered in this series can be shared with either method.
