Teaching Routines / Pass the Problem
Each group does one step of a problem and stops. It moves to the next table, who check that step before adding theirs — so by the end, four groups have built one answer and everybody has had to mark somebody else's work.

Pass the problem is a structure for multi-step work in which each group completes only one step and then passes the paper to another group. The receiving group must check the previous step before adding the next. The problem circulates until it is finished, then returns home.
It turns a procedure into an inspection task. In ordinary group work a child who cannot do step two waits for somebody who can; here every group has to read, judge and then extend somebody else's reasoning, which is a harder and more useful job than doing your own from the start.
Eleven minutes. The going-home stage is the pay-off and it is the one that gets cut, which is a shame because finding the exact step where an answer went wrong is the whole skill.
Anything with three or four genuinely separate steps. Multi-step word problems, a calculation with several stages, an experiment write-up, a piece of extended reasoning in history.
What does not work is a problem where step two is obvious once step one is done — the passing then adds nothing but handling time.
Making groups flag an error rather than silently fix it was the change that made this worth doing. Early on, groups would notice a mistake, quietly correct it, and carry on — which is generous and completely destroys the point, because the group who made the error never found out and the going-home stage had nothing to find. Now the rule is: if you think it is wrong, write why underneath and then carry on from the corrected version. That single instruction turned it from a relay race into a peer-assessment activity. The other thing is stopping after one step. Children hate it and will finish the whole problem if you let them, so I now physically take the sheets at the timer whether they are done or not, and after two or three goes they stop racing. With Year 5 I use three groups, not four — four passes and the sheet gets messy enough that the last group cannot read it.
| Year group | US grade | What to change | How long |
|---|---|---|---|
| Years 3–4 | Grades 2–3 | Two steps and two passes. Model the checking out loud first. | 8 min |
| Years 5–6 | Grades 4–5 | Three passes, errors flagged in writing, going-home stage protected. | 11 min |
| Year 7 and up | Grades 6–8 | Plant a deliberate error in one problem and see how far it travels. | 15 min |
