Four Corners

Four opinions, one in each corner of the room. Everybody has to physically stand somewhere — which means everybody has to have a view, including the children who have spent five years avoiding having one.

Committing is the point. You cannot abstain by standing still; the floor makes you choose.

Four opinions, no printing. Say them, or write them on four sheets of paper before the lesson.

Ten minutes, and they move. The one to reach for after a long stretch of sitting.

What is the Four Corners activity?

Four Corners is a cooperative learning structure in which the teacher puts a different opinion or answer in each corner of the room, and every child walks to the corner they agree with. They then build a case with the people who chose the same corner, hear one speaker from each of the others, and are offered the chance to move.

It is a discussion structure that runs on the floor rather than on paper, and its real function is that abstaining is impossible. A child can stay quiet in a debate; they cannot stand in the middle of the room.

How do you run Four Corners, step by step?

Choose a corner (about a minute). Read the statement, name the four positions, and send them. Silently — talking on the way is how children end up in their friend’s corner rather than their own.
Talk in corners (about three minutes). Everyone here already agrees, so the job is building the strongest case, not persuading each other. Ask each corner to pick a speaker.
Hear each corner (about four minutes). One speaker per corner, in turn. Then tell the class they may move, and give them ten seconds to do it.

That last invitation is the whole activity. A child crossing the room after hearing an argument is changing their mind in public, which is rare enough to be worth naming when it happens.

What makes a good Four Corners statement?

Something arguable, with four positions that are genuinely different rather than four degrees of the same one. “Strongly agree / agree / disagree / strongly disagree” works but is the weakest version — it sorts by confidence rather than by reasoning.

Better: four candidate causes, four characters who could be to blame, four possible methods, four things that mattered most. In maths, four different answers to the same problem, only one of which is right, turns it into an explanation task.

From the classroom

Two things I had to learn. The first is that you must send them silently, and you must say so before you read the options, not after — once children hear the choices they start looking at each other, and then you are measuring friendship groups. The second is the ten seconds to move at the end: I used to skip it because we were running short, and skipping it quietly teaches the class that the discussion never had any consequences. Now I protect it even if I have to cut a corner’s speaker. One warning about the room: four corners means four groups the size of half a table each, and in a full classroom with thirty children the corners are shoulder to shoulder. I use the four walls rather than the corners, and I move two tables first. With Year 6 I now also ask the corner that lost the most people to say why they think that happened, which is a better question than anything I had planned.

What usually goes wrong with Four Corners?

Children follow their friends. Silent movement fixes most of it; asking them to write their choice down before they stand up fixes the rest.
One corner is empty. Fine, and worth naming — but if it happens every time, your options are not genuinely balanced.
The corners argue with each other during stage two instead of building their own case. They are not debating yet.
Nobody moves at the end because you did not actually invite them to, or did not leave a silence long enough for it to feel allowed.

Which year groups is Four Corners for?

Year group	US grade	What to change	How long
Years 1–2	K – Grade 1	Two corners, not four. A picture in each corner rather than a sentence.	6 min
Years 3–4	Grades 2–3	Four corners. Give a sentence stem for the speaker.	10 min
Years 5–6 and up	Grades 4–8	Ask each corner to anticipate the strongest objection to their own case.	12 min

Four Corners compared with the other opinion structures

Human Line-Up sorts the class along a line by degree rather than into four camps — better when the disagreement is about how much, not which.
Silent Debate gets the same range of views on paper without moving anybody, which matters in a small room.
Think Pair Share is what to use when you want everybody to answer but you do not want to spend ten minutes or move the furniture.
