Teacher guide

One page: what you need, the first five minutes, what you control during a live activity, and quick fixes.

What you need

A projector or shared screen for the host view. The whole class watches this together.
A device per student. Chromebooks or tablets are perfect. Students install nothing and never make accounts.
Any device for you. A second device for the private teacher console is optional but handy for moderation.

The first five minutes

Open the library, pick an activity, and press Host this.
A room code appears on the projector. Students open this site on their devices and type the code and their first name.
Watch names appear on the projector. When everyone is in, press Start.
From there, you set the pace. Reveals and results wait for you, and the continue button always says what happens next.

Trying it without a class? Every activity has a Preview button that shows your screen and simulated students side by side. Run one activity in Preview before your first real class; it is the fastest way to know what your students will see.

What you control during a live activity

Pacing. Payoff moments (reveals, results, winners) never auto-advance. The class moves when you press the button.
The teacher console. Open the teacher console on a second device and enter the room code plus the teacher PIN. The PIN sits behind a deliberate two-tap reveal on the host screen so the class does not see it. One rule to remember: anything the projector's buttons can do, the console can do, and the console never jumps ahead of what the class has seen.
Moderation. From the console you can hide any student response or remove a student from the room. A text filter also runs on everything students submit.
Drawings. Activities with student drawings include a teacher preview step, so nothing hand-drawn reaches the projector without your approval.
Sound. The speaker chip on each screen mutes sound effects, and it remembers the choice.

Quick fixes

If this happens	Do this
A student's room code will not work	Have them retype the code exactly as it appears on the projector. If the activity already ended, host it again; each run gets a fresh code.
A student's device drops off the wifi	Have them refresh the page. They rejoin automatically with their work intact.
You close or refresh the host tab by accident	Reopen it. The room resumes where it was, even if the mistake happens mid-activity.
Something on the projector needs to go	Hide that response from the teacher console. It disappears everywhere immediately.
A student joined late	Nothing to do. Late joiners drop straight into the current step.
An AI step feels slow	With a full class, AI summaries can take around 20 seconds. The room is not stuck; the screen says what it is working on.

Privacy in one breath

No student accounts. First names only. Student work is deleted when the activity ends. When AI summarizes class answers, student names are stripped first and never sent. Full details on the privacy page.
