The Opinion Line: A No-Prep Whiteboard Game That Scales From Kindergarten to Adult Class
The Opinion Line is a whiteboard game where students physically stand along an imaginary scale to show agreement with a statement, then defend their spot in English — no photocopies, no cards, just a marker and floor space.

We picked this one up from a co-teacher in Bundang back in 2015, and it's still the game we tell new teachers to learn first, because it survives almost any class size and almost any level with zero prep the night before.
How it works
Draw a line across your whiteboard, or just point at one wall and then the other. One end is "Strongly Agree," the other is "Strongly Disagree." That's the whole setup.
Read a statement out loud. Students walk to the spot on the classroom floor that matches how they feel — all the way to one wall, dead center, wherever. Then you point at two or three of them and ask why. That's it. One statement can eat two minutes or ten depending on how much your class likes to argue.
For a class of 8 to 15 this works well because everyone is visible and nobody can hide in a back row doing nothing. In a class of 20-plus it gets crowded and slower, so if your hagwon runs bigger groups, cut the walking and have students point instead.
Scaling by level
| Level | Statement style | What you're drilling |
|---|---|---|
| Elementary (age 7-9) | "Pizza is better than kimchi." Simple, silly, one clause. | Basic opinion phrases: I think, I like |
| Middle | "Students should get more homework." | Because clauses, agree/disagree language |
| High school | "AI should write essays for students." | Hedging language: I partly agree, on the other hand |
| Adult / advanced | "Remote work makes teams less creative." | Concession and rebuttal structures |
The statement is the only thing you change. Everything else about the game stays the same, which is why it takes about ninety seconds to reset for a completely different class an hour later.
Running it with mixed levels
If you've got a wide spread of ability in one room — common in smaller hagwons where the director doesn't split by TOPIK-style testing — pair a strong student with a weaker one before the statement drops. The strong student has to get the weaker one to explain their position in a full sentence before either of them can move to a new spot for the next round. This slows the game down but it's the version that actually produces language rather than just pointing.
What doesn't work
Kids figure out fast that standing exactly in the middle avoids getting called on. Ban dead center after round two, or make "no middle allowed" a rule from the start. Also: statements that are too close to real classroom politics ("our school should have less homework") can go sideways fast in a hagwon where the director might be listening through the door. Keep the sharper opinions for high schoolers you know well.
We've run this in classes of six and in classes of nineteen crammed into a room built for twelve. Six is more honest. Nineteen is louder and faster and, if you're being honest, more fun to watch.
