CHAPTER 1 OF 12 · Back to contents
1. Turn conditions into a checklist
A question can contain several requirements in its sentence, diagram, table and command word. Rewrite each as a short check before solving so a prominent clue does not hide a smaller decisive condition.
Build the explanation by naming the complete set of stated conditions and the candidate answer or explanation. A remembered keyword is not enough: connect the observation to the mechanism and identify what would have to change for the conclusion to change.
Repair the nearest misconception by checking the condition-by-condition audit and returning to hidden assumptions qualifiers units exceptions and final answer form. State why the tempting alternative is too strong, incomplete or about a different stage.
- Check the complete set of stated conditions.
- Check the candidate answer or explanation.
- Check the condition-by-condition audit.
- Check hidden assumptions qualifiers units exceptions and final answer form.

2. Distinguish possible from valid
A candidate may fit one fact and still fail another. Possible means compatible with some evidence; valid for the question means it satisfies every required condition without adding an unsupported assumption.
Build the explanation by naming the complete set of stated conditions and the candidate answer or explanation. A remembered keyword is not enough: connect the observation to the mechanism and identify what would have to change for the conclusion to change.
Repair the nearest misconception by checking the condition-by-condition audit and returning to hidden assumptions qualifiers units exceptions and final answer form. State why the tempting alternative is too strong, incomplete or about a different stage.
CHAPTER 3 OF 12 · Back to contents
3. Use intersection thinking
Treat each condition as a filter. The valid set is the overlap of all filters, not the result of passing the easiest or most familiar one.
Build the explanation by naming the complete set of stated conditions and the candidate answer or explanation. A remembered keyword is not enough: connect the observation to the mechanism and identify what would have to change for the conclusion to change.
Repair the nearest misconception by checking the condition-by-condition audit and returning to hidden assumptions qualifiers units exceptions and final answer form. State why the tempting alternative is too strong, incomplete or about a different stage.
CHAPTER 4 OF 12 · Back to contents
4. Preserve direction and boundary
Words such as before, after, only, at least, exactly, except and not change the allowed set. Copy them into the checklist instead of reducing the question to its topic noun.
Build the explanation by naming the complete set of stated conditions and the candidate answer or explanation. A remembered keyword is not enough: connect the observation to the mechanism and identify what would have to change for the conclusion to change.
Repair the nearest misconception by checking the condition-by-condition audit and returning to hidden assumptions qualifiers units exceptions and final answer form. State why the tempting alternative is too strong, incomplete or about a different stage.
CHAPTER 5 OF 12 · Back to contents
5. Audit English answers
A response may need the correct referent, tense, relationship and answer form at once. A grammatically smooth sentence still fails if it answers the wrong person, time or reason.
Build the explanation by naming the complete set of stated conditions and the candidate answer or explanation. A remembered keyword is not enough: connect the observation to the mechanism and identify what would have to change for the conclusion to change.
Repair the nearest misconception by checking the condition-by-condition audit and returning to hidden assumptions qualifiers units exceptions and final answer form. State why the tempting alternative is too strong, incomplete or about a different stage.
CHAPTER 6 OF 12 · Back to contents
6. Audit Mathematics answers
A numerical result must also meet domain, unit, whole-number, range and requested-form constraints. Solving an equation generates candidates; substitution and context decide which remain admissible.
Build the explanation by naming the complete set of stated conditions and the candidate answer or explanation. A remembered keyword is not enough: connect the observation to the mechanism and identify what would have to change for the conclusion to change.
Repair the nearest misconception by checking the condition-by-condition audit and returning to hidden assumptions qualifiers units exceptions and final answer form. State why the tempting alternative is too strong, incomplete or about a different stage.
CHAPTER 7 OF 12 · Back to contents
7. Audit Science explanations
An explanation must match the observed change, mechanism, controlled comparison and strength of evidence. A true science fact is not automatically the fact that explains this setup.
Build the explanation by naming the complete set of stated conditions and the candidate answer or explanation. A remembered keyword is not enough: connect the observation to the mechanism and identify what would have to change for the conclusion to change.
Repair the nearest misconception by checking the condition-by-condition audit and returning to hidden assumptions qualifiers units exceptions and final answer form. State why the tempting alternative is too strong, incomplete or about a different stage.
CHAPTER 8 OF 12 · Back to contents
8. Finish with a rejection proof
Before locking the answer, test the closest alternative and name the condition it fails. This brief rejection catches incomplete solutions faster than rereading the entire question without a plan.

9. Worked examples
Worked case 1: Choose a number greater than 20, even and divisible by 3. Does 22 qualify?
Controlled answer. No. It is greater than 20 and even but fails divisibility by 3.
Mechanism. Identify the exact relationship, apply the relevant rule and preserve every stated condition. A surface clue may be compatible with several explanations, so the answer must show what makes this case decisive.
Misconception repair. Do not turn partial evidence into complete proof. Name the closest wrong answer, identify its missing condition and explain why the observed evidence supports the narrower conclusion.
Transfer. Find the smallest valid number. Solve the altered case from the mechanism rather than copying the previous wording.
Reverse construction. Begin with the controlled answer “No” and invent a fresh prompt that would justify it for the same reason. Then change one decisive condition to create a near-nonexample. This reverse task checks whether the learner owns the boundary rather than merely recognising the original sentence.
Explanation standard. A complete explanation names the observation, connects it to the rule and limits the conclusion to what follows. It should remain valid if decorative details are removed. If the explanation depends on the story topic instead of the decisive relation, rebuild it.
Audit. Recheck the complete set of stated conditions, the candidate answer or explanation, the condition-by-condition audit, hidden assumptions qualifiers units exceptions and final answer form. Decide whether the evidence proves the conclusion or only supports a limited statement.
Worked case 2: A composition prompt asks for a past event and a lesson learned. Is a vivid present-tense description alone enough?

10. Independent practice
Practice 1: A sentence must use neither…nor and agree with the nearer subject. What two checks are needed?
Explained answer. The paired construction and subject–verb agreement. Passing only the connector check is incomplete.
Delayed transfer. Create a singular-nearer and plural-nearer pair. Cover the answer later and rebuild the chain.
Control question. Which exact condition does the nearest wrong answer miss? State it before checking.
Extension. Change one decisive feature while keeping the story similar. Explain why the conclusion now stays or changes.
Independent proof. Restate the answer without copying its wording. Your version must identify the evidence, the governing relationship and the boundary of the claim. Then write one fact that would be relevant but still insufficient on its own. This separates explanation from repetition.
Delayed comparison. Save this item beside the near-nonexample you created. On the next attempt, compare them before answering and point to the single feature that controls the difference. If more than one feature changed, revise the pair so the comparison stays fair.
Practice 2: A rectangle has perimeter 30 cm and whole-number sides. Is 7 cm by 8 cm valid?
Explained answer. Yes. Twice 7 plus 8 is 30 and both sides are whole numbers.
Delayed transfer. Test 6.5 cm by 8.5 cm against the whole-number condition. Cover the answer later and rebuild the chain.
Control question. Which exact condition does the nearest wrong answer miss? State it before checking.
Extension. Change one decisive feature while keeping the story similar. Explain why the conclusion now stays or changes.

Practice 3: A science answer says temperature increased. The command is explain. What is missing?
Explained answer. A mechanism linking the changed condition to the temperature increase. Description alone does not satisfy explain.
Delayed transfer. Write the causal chain. Cover the answer later and rebuild the chain.
Control question. Which exact condition does the nearest wrong answer miss? State it before checking.
Extension. Change one decisive feature while keeping the story similar. Explain why the conclusion now stays or changes.

Practice 6: How should an unstated assumption be treated?
Explained answer. Do not use it unless the question or accepted background knowledge warrants it. Invented facts can make an invalid option appear valid.
Delayed transfer. Remove one assumption from a worked answer. Cover the answer later and rebuild the chain.
Control question. Which exact condition does the nearest wrong answer miss? State it before checking.
Extension. Change one decisive feature while keeping the story similar. Explain why the conclusion now stays or changes.

11. Delayed transfer
On day one, solve clear examples. On day three, mix examples, near-nonexamples and incomplete evidence. On day seven, solve without headings or a word bank. Delay reveals whether the method can be reconstructed independently.
Keep an error log for the first failed stage: reading, representation, rule, execution or checking. The earliest failure identifies the repair.
Interleave this skill with neighbouring ideas that share vocabulary. Classify each item only after naming the distinguishing condition.
In timed work, mark the relationship, apply the rule, write the conclusion and audit one condition. If checking changes the answer, record the overlooked feature.
Create a teach-back card with a near-nonexample on the front and the repaired mechanism on the back. Explain why the tempting answer fails.
Finish with one basic example, one boundary case and one transfer case. Supply explanations that a classmate can verify.
For a second delayed test, reverse the direction: start from a conclusion and invent evidence that would justify it, then evidence that would be insufficient. This exposes the boundary between relevance and proof.

12. Family guidance and FAQs
Guidance for parents and tutors
Ask for the decisive condition before confirming the answer. Use prompts such as “What exactly happened?”, “Which stage or meaning is this?” and “What would prove it?”
Fade support from labelled examples to mixed questions and delayed open response. Independent retrieval after time and topic change is the target.
Praise precise claim control. Narrowing an answer when evidence is incomplete is scientific and academic strength.
Frequently asked questions
Should I memorise the rule?
Memorise the compact rule, then practise examples and near-nonexamples so the conditions remain visible.
What if two answers seem possible?
Return to the exact relationship and choose the option satisfying every stated condition without adding facts.
Why delay practice?
Immediate repetition may depend on the recent explanation; delay tests reconstruction.
How should an error be corrected?
Name the first failed stage and practise it with a changed example.
When is the skill ready?
When the learner can explain, apply and transfer it after a delay.
What is the final audit?
Check relationship, mechanism, claim strength and whole-question fit.
