  • Names a rule.

The lesson

Warm-up — a day with no rules

5 min
  1. Ask what playtime would be like if there were no rules at all.
  2. Collect three problems. Do not solve them yet.

Teach — every rule fixes something

13 min
  1. Take 'walk in the corridor'. Ask what happens without it. Collisions.
  2. Write the rule and the problem side by side.
  3. Do 'put your hand up' and 'put litter in the bin' the same way.
  4. Read the park sign. Notice the rules are different because the place is different.
  5. Say the pattern: a rule is an answer to a problem somebody had.
“Somebody made that rule because something kept going wrong. What was it?”

Guided practice — rule and reason

12 min
  1. Pairs take four rules and write the problem each one prevents.
  2. They sort them into school rules and park rules.
  3. Take feedback on any rule that belongs in both places.

Independent practice

8 min
  1. Students complete the school-and-park-rules page.
  2. Read each rule aloud.

Close

2 min
  1. Give a rule. Take the problem it prevents.

What goes wrong, and why

Each of these is a reasoning error rather than carelessness. The fix addresses the reasoning.

Says rules exist 'because grown-ups say so'.

Why: That is who announces them, and it is the visible cause.

Fix: Ask what goes wrong without the rule. The answer is the real reason, and it is not about authority.

Thinks every rule applies everywhere.

Why: A rule feels like a fact.

Fix: Compare the school list with the park sign. Different places, different problems, different rules.

Says a rule is there 'to stop you having fun'.

Why: Rules do stop some things, and those are the memorable ones.

Fix: Take the swing rule. It stops one person having all the fun, so more people have some.

If they are not there yet

  • Two rules rather than four.
  • Give the problem and name the rule.

If they finish early

  • Suggest a rule the class needs and say what problem it fixes.
  • Find a rule that no longer has a problem behind it.
  • Say what makes a rule fair.

Exit ticket

Name a rule at our school. What would go wrong without it?

What to look for: A named problem. 'Because we have to' means the what-goes-wrong question needs another lesson.

Questions about Why We Have Rules

How long does the Why We Have Rules lesson take?

40 minutes, split across 5 timed sections: warm-up 5 min, teach 13 min, guided practice 12 min, independent practice 8 min, close 2 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 Why We Have Rules teach?

D2.Civ.3.K-2 — D2.Civ.3.K-2, Civics for Kindergarten to Grade 2: “Explain the need for and purposes of rules in various settings inside and outside of school.” In plain terms, explain why rules exist, at school and outside it.

What do I need to teach this lesson?

The park rules sign, the class rules 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: says rules exist 'because grown-ups say so'; thinks every rule applies everywhere and says a rule is there 'to stop you having fun'. 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: “Name a rule at our school. What would go wrong without it?.” A named problem. 'Because we have to' means the what-goes-wrong question needs another lesson. 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 Why We Have Rules?

Yes — 1 printable D2.Civ.3.K-2 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 Why We Have Rules 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.
