Objective
Students will be able to state the problem a rule was written to solve and what would happen without it.
Students are successful when they can
- Names the problem behind a rule.
- Says what would go wrong if it were dropped.
- Distinguishes the rule's wording from its purpose.
What you need
- The emigration ledger, the harbour return and the health table
- Eight rule cards with blank problem boxes
- The printable practice sheet linked at the end of this plan
The lesson
Warm-up — no refunds
5 min- Read the ledger's note: fares to be paid before sailing, no refunds.
- Ask who wrote that rule and what they were worried about.
Teach — the worry, then the rule
17 min- Name the agent's worry: a ship sails and the fare is never paid.
- Write the problem above the rule and the rule below it.
- Take 'a medical officer must report annually'. Problem: conditions ignored year after year.
- Take 'the census every ten years'. Problem: change measured by guesswork.
- Take 'harbour dues set by the board'. Problem: one shipper charged more than another.
- Say the method: read the rule, then ask what goes wrong if nobody follows it.
- Add the harder point: a rule can solve the writer's problem and create somebody else's. No refunds solves the agent's and creates Thomas Reid's.
“What was going wrong before somebody wrote this down?”
Guided practice — fill the boxes
15 min- Pairs take eight rule cards and write the problem each solves.
- For three, they name whose problem it solves and whose it creates.
- Groups challenge one answer that only restates the rule.
Independent practice
10 min- Students complete the 'The Problem Behind the Rule' page.
- Watch for restatement instead of purpose.
Close
3 min- Take one school rule and name whose problem it solves.
What goes wrong, and why
Each of these is a reasoning error rather than carelessness. The fix addresses the reasoning.
Restates the rule as its purpose.
Why: The rule is the available sentence.
Fix: 'Because you must' is not a purpose. Say what goes wrong without it.
Assumes a rule with a purpose is fair to everybody.
Why: Purpose sounds like justification.
Fix: No refunds protects the agent and strands the poor. Ask whose problem it solved.
Thinks rules are written by nobody in particular.
Why: They arrive already made.
Fix: Each of these has an author with an interest. Name them.
If they are not there yet
- Four rule cards with the problem offered as a choice of two.
- Work only with the ledger's rule.
If they finish early
- Find a rule whose problem no longer exists.
- Write a rule that would have solved Thomas Reid's problem.
- Say which of the eight rules would be hardest to enforce.
Exit ticket
Why did the agent's ledger say fares must be paid before sailing? Whose problem did that solve, and whose did it create?
What to look for: It protects the agent from unpaid passages and strands anybody who cannot raise the fare. One side only means the second half is missing.

Questions about The Problem Behind the Rule
How long does the The Problem Behind the Rule lesson take?
50 minutes, split across 5 timed sections: warm-up 5 min, teach 17 min, guided practice 15 min, independent practice 10 min, close 3 min. The minutes are stated per section and add up to the stated length, so the plan can be cut or extended at a section boundary rather than abandoned halfway.
Which standard does The Problem Behind the Rule teach?
D2.Civ.3.3-5 — D2.Civ.3.3-5, Civics for Grade 3 to Grade 5: “Examine the origins and purposes of rules, laws, and key U.S. constitutional provisions.” In plain terms, look at where rules, laws and key parts of the US Constitution came from.
What do I need to teach this lesson?
The emigration ledger, the harbour return and the health table, eight rule cards with blank problem boxes and the printable practice sheet linked at the end of this plan. Everything listed is either ordinary classroom equipment or a free printable from this site — there is nothing to buy and nothing to prepare beyond photocopying.
What mistakes should I expect in this lesson?
Three, each a reasoning error rather than carelessness: restates the rule as its purpose; assumes a rule with a purpose is fair to everybody and thinks rules are written by nobody in particular. The plan gives the thinking behind each one and the teaching move that addresses the thinking rather than the symptom.
How do I know whether the lesson worked?
The exit ticket asks: “Why did the agent's ledger say fares must be paid before sailing? Whose problem did that solve, and whose did it create?.” It protects the agent from unpaid passages and strands anybody who cannot raise the fare. One side only means the second half is missing. That tells you whether the class needs a reteach or a thirty-second conversation before you plan tomorrow.
Is there a worksheet to go with The Problem Behind the Rule?
Yes — 1 printable D2.Civ.3.3-5 worksheet, linked at the end of the plan and free like the rest of the site. Each one comes with an answer key and 25 versions, so the practice after the lesson can be a different paper on every desk.
Is The Problem Behind the Rule free to use?
Yes. The plan, its printables and their answer keys are free to read, print and photocopy for your own class, with no account and no email capture. It was last reviewed on 7 September 2026. Please do not resell it or republish it as your own.
