5 ways to turn a boring warm-up into a reveal game
Every class starts the same way: attendance, a slide, maybe a question nobody answers. A reveal game flips that. Students have to earn the picture, one correct answer at a time, and the room gets quiet in the good way. Here are five warm-ups that work well as a masked photo, built in under five minutes each.

1. Guess the vocabulary word
Upload a picture of the word (a photo of a volcano for “eruption,” a map pin for “location”). Mask it into two or three pieces, each guarded by a definition or a fill-in-the-blank sentence. Right answer, next piece lifts.
2. Who is this historical figure
A portrait, split into masks. Each mask’s question is a fact about the person: a date, an event, a quote. Students narrow it down as the picture reveals, which turns a recall drill into a small deduction game.
3. Map the location
A photo of a country, city, or landmark. Ask a geography question per mask: capital, border country, a local landmark’s name. Works well as a five-minute lesson opener for a unit you’re about to start.
4. The math answer is the key
Any photo works here, since the questions carry the theme. Set each mask’s answer to a calculation result. Students solve the problem, type the number, and the picture rewards them for getting it right instead of just checking a worksheet.
5. End-of-unit recap
Save this one for a Friday. Pull one question from each topic covered that week. By the time the last mask lifts, the class has just self-tested the whole week without it feeling like a quiz.
Why it works better than a slide
The picture is the incentive, not the questions. Kids will push through a definition they’d otherwise skip, because they want to see what’s under the mask. And since secret.pics runs from one link with no login for players, it drops into whatever you’re already screen-sharing, no new app for the class to set up.
