An analogy asks the learner to notice a relationship, not merely two familiar words. Wheel is to bicycle is different from rain is to flood, and both are different again from knife is to cut.
This Secondary 1–2 practice guide develops four recurring analogy relationships: part–whole, cause–result, object–function and degree. The goal is to make the hidden relationship visible so learners can reason through unfamiliar vocabulary rather than guess from surface similarity.
This is an original eduKateSG practice guide. It is not an official examination paper or standardised test.
Why Analogy Questions Feel Harder Than They Look
The words themselves may be simple. The difficult part is often identifying the exact relationship.
Consider:
page : book
A weak response may say, “Both are about reading.”
A stronger response says, “A page is a part of a book.”
Once the relationship is named, the learner can search for another pair with the same structure.
The Hidden Vocabulary Problem: Topic Similarity Is Not Relationship Similarity
Students often choose an answer because the words belong to the same topic.
doctor : hospital and teacher : school may both involve person-to-workplace relationships.
But doctor : medicine is not the same relationship simply because the words remain in the same topic.
The test is not “Do these words go together?” It is “Do they go together in the same way?”
1. Part–Whole Relationships
A part belongs within a larger whole.
Examples:
- wheel : bicycle;
- chapter : book;
- branch : tree;
- keyboard : computer.
Worked example
Petal : flower :: page : ?
If petal is part of flower, page should be part of a larger whole.
Answer: book.
2. Cause–Result Relationships
One event contributes to or produces another.
Examples:
- heavy rain : flooding;
- practice : improvement;
- collision : damage;
- heat : expansion in an appropriate context.
Be careful: sequence alone is not enough. If Event B comes after Event A, that does not automatically prove A caused B.
Worked example
spark : fire :: infection : ?
Possible answer: illness, if the intended relationship is a cause leading to a result. Context still matters.
3. Object–Function Relationships
The relationship identifies what something is commonly used to do.
Examples:
- knife : cut;
- thermometer : measure temperature;
- key : unlock;
- filter : remove selected material from a flow or mixture.
One object may have several functions, so the analogy must use the function intended by the question.
4. Degree Relationships
Words can describe similar meanings at different intensities.
Examples:
- warm : hot;
- annoyed : furious;
- tired : exhausted;
- concerned : alarmed.
This relationship is not simply synonymy. The second word usually expresses a stronger or weaker degree.
A First-Principles Analogy Method
- Say what the first word is.
- Say what the second word is.
- Write one short relationship sentence.
- Apply that sentence to the candidate answer.
- Reject answers that fit the topic but not the relationship.
Example
engine : car :: heart : body
Possible relationship sentence: “The first is a central component that helps the larger system operate.”
The sentence is not scientifically identical in every detail, but it reveals the intended structural comparison more clearly than “both are important.”
Practice A — Name the Relationship
A1. finger : hand
A2. study : knowledge gain
A3. brush : paint
A4. cool : cold
Suggested answers
A1 part–whole. A2 cause/contribution–result. A3 tool–function. A4 degree.
Practice B — Complete the Analogy
B1. page : book :: room : ______
B2. key : unlock :: pen : ______
B3. tired : exhausted :: worried : ______
B4. storm : damage :: collision : ______
Possible answers: building/house, write, alarmed/terrified depending on the intended scale, damage.
Practice C — Reject the Tempting Wrong Answer
Wheel : bicycle :: page : ?
Options: library, book, author, paper.
Book is best because a page is part of a book. Paper is related in material, author in production, and library in location/collection—but none preserves the part–whole relationship.
Practice D — Build Your Own Analogy
Create one analogy for each relationship:
- part–whole;
- cause–result;
- object–function;
- degree.
Then explain the relationship in one sentence. This is harder than selecting an answer and reveals whether the learner actually controls the pattern.
Common Secondary 1–2 Analogy Errors
Choosing by topic
The student sees two science words and assumes they form the right pair.
Reversing direction
Wheel is part of bicycle is not identical to bicycle is part of wheel.
Using vague relationship language
“They are connected” is rarely specific enough.
Ignoring degree
Two near-synonyms may differ sharply in intensity.
Inventing causation
Words that often occur together are not automatically cause and result.
How We Teach Analogy Relationships in Small Groups
The Clementi teaching model emphasises diagnosis, rebuilding from the first unstable point, controlled complexity, thinking aloud, retrieval and mixed application. The same structure works here. citeturn497227view0
Warm-up retrieval
Students name familiar relationships from earlier lessons.
Single relationship fence
Only part–whole analogies appear at first.
Contrast
A tempting topic-related wrong answer is compared with the correct relationship match.
Mixed recognition
Several relationship types are interleaved.
Independent generation
Students build and explain their own analogies.
Error review
We identify whether the difficulty is vocabulary meaning, relation recognition, direction or explanation.
Three Learner Pathways
Repair
The student recognises words but cannot state relationships. We return to concrete pairs and explicit relation sentences.
Stabilisation
The student succeeds when relation types are grouped but struggles when they are mixed. We interleave and require explanation.
Extension
The student handles basic relations and moves into multiple possible relations, ambiguity, figurative analogy and argument by analogy.
What Progress Should Look Like
The student begins to:
- name relationships precisely;
- reject topic-only distractors;
- track direction;
- explain why an option fits;
- recognise degree and function distinctions;
- transfer analogy reasoning into comprehension and writing.
Frequently Asked Questions
Are analogies just vocabulary puzzles?
No. They train semantic relationships and structured comparison, which support comprehension, writing and reasoning.
Should students memorise analogy types?
Labels help, but the deeper goal is being able to express the relationship accurately in ordinary language.
What if two answers seem possible?
Write the relationship sentence. The better answer is the one that preserves the most specific intended relationship with the least extra assumption.
Can analogies be imperfect?
Yes. Many real analogies share only selected features. Students should learn what aspect is being compared rather than assume the two things are identical.
