Free Classroom Tools for Teachers

Four browser-based tools that just work — name picker, group generator, noise meter, tally counter. No signup, no ads, no audio recorded, no student data leaves your device.

Random Name Picker

Free spinning name wheel for cold-calling or random groups. Save your class list in this browser — no account, no upload.

Group Generator

Random groups of any size from your class list. Seed for reproducible groups. Avoid repeating last week's pairs automatically.

Classroom Noise Meter

Free microphone-based noise meter with bouncy-ball, bar, and accessible color modes. Nothing recorded — privacy-first.

Tally Counter

Single counter or multi-counter grid. Tap to count behaviour, votes, attempts. Persists across reloads.

Classroom Timer

Large-display projectable countdown. Smartboard-ready — great for transitions, tests, and timed activities.

Study Timer

Pomodoro-style focus sessions. Structured work/break cycles for independent study periods.

Debate Timer

Multi-phase debate round timer. Supports PF, LD, Policy, WSDC, and British Parliamentary formats.

Presentation Timer

Count down student presentations. Full-screen display with configurable time limit.

Breathing Timer

Guided breathing for classroom brain breaks. Calm the room between activities.

Why a single classroom toolkit?

Most online classroom tools force you to bounce between three or four tabs — one for the name wheel, another for the group maker, a third for the noise display. Each is its own ad-laden site with its own signup flow. This hub puts the four we use most in one place, with one consistent design language and a single privacy promise: nothing leaves your device unless you choose to share it.

How teachers actually use these tools

  • Cold-call rotation — Open the name picker, paste your roster once on Monday, leave the "remove after pick" toggle on. Spin during questioning so every student is called once before any repeat.
  • Random groups for projects — Open the group generator with the "avoid last week's pairs" toggle on. The shuffler biases against repeating pairs so groups stay fresh across multi-week units.
  • Quiet work without yelling — Project the noise meter during seatwork. The bouncy balls float higher when the room is loud; students self-regulate without your voice rising.
  • Behaviour and participation tracking — Open the tally counter in multi-counter mode, paste one column per behaviour or row, tap to record. The count persists across the period so you can report data at the end of class.
  • Timed activities — Pair any tool with the classroom timer for transitions, tests, and group work.

What we don't do

We don't track students. We don't store class lists on a server. We don't require a Google or Apple sign-in. We don't insert ads into the tool itself. We don't analyse your microphone audio (the noise meter only reads amplitude on your device). If your district has a privacy review process, these tools are usually approved on first pass because there is no student PII handling and no data leaving the device.

Print, project, embed

All four tools work in browser full-screen (press F11 on Windows / ChromeOS, the green full-screen button on macOS). The name picker and group generator pages are designed so the result displays full-width when projected. The group generator output is also legible if you print the browser tab (the cards reflow onto letter paper).

How this compares to wheelofnames and online-stopwatch

We are not trying to out-rank the giant single-purpose sites on head terms — wheelofnames.com has a 15-year backlink moat and owns "name picker wheel" on Google. What we do differently is keep the four most-used classroom tools in one consistent, signup-free, ad-free toolkit with explicit privacy guarantees. If you want a single bookmark in your classroom browser, that's us.

Classroom Toolkit FAQ

Are these classroom tools really free? What's the catch?
Yes, all of these classroom tools are completely free with no signup, no ads, and no email gate. There is no catch. We pay for hosting because the rest of GoTimer (timers and challenges) is supported by occasional small donations and our own time. Everything teacher-facing on this hub will stay free indefinitely.
Do these tools work on a smartboard or projector?
Yes. Each tool is built for full-screen use on any display — interactive whiteboards, classroom projectors, monitors, TVs, and Chromebooks. Press F11 in any browser to enter full screen on Windows or ChromeOS, or use the green full-screen button on macOS. Large readable typography and high-contrast colours work from the back of the room.
Do I need to install anything or create an account?
No. All four tools run inside the web browser. Nothing is installed, no extension is needed, and no account is created. Your class lists and counter state are stored in your browser's local storage on the same device, so they persist between visits but never leave your computer.
Is any audio or student data recorded?
No. The noise meter uses the microphone only to read amplitude in real time — nothing is recorded, transmitted, or saved. Class lists used by the name picker and group generator are stored in your browser's local storage only; they never leave your device. The tally counter is purely local.
Can I use these for a substitute teacher or shared classroom?
Yes. Bookmark this page (or any of the individual tool pages) on the classroom computer's home screen and a substitute can use them immediately without setup. Because state is stored locally per browser profile, each teacher who logs into a shared computer has their own class list, tally state, and last-used settings.
Will these tools work on a Chromebook?
Yes — these tools are tested specifically on Chromebooks because so many classrooms run them. The name picker uses CSS transforms for the spinning wheel (not Canvas), keeping the animation smooth even on low-end Celeron Chromebooks. The noise meter falls back gracefully if the microphone is unavailable.
Can students see my class list?
Students only see what you display on the projector. If you don't want last names visible, the name picker accepts first names, nicknames, or numbered placeholders (Student 1, Student 2, …). The class list is never shown unless the wheel is rendered or you scroll the input box into view.
What if I'm the only one in my school using GoTimer?
Then you're welcome here. These tools are designed for individual teachers — no admin setup, no IT approval needed, no licence, no roster sync. They're also commonly added to district-curated EdTech listicles like Edutopia, Larry Ferlazzo's blog, and WeAreTeachers, so if your district has a vetted-tools list, ask them to consider adding this one.
