Top 100 Primary 6 Vocabulary List | Critical Thinking, Evidence & Reasoning Words for Grade 6 Students

This Top 100 Primary 6 Vocabulary List focuses on critical thinking vocabulary, evidence words, reasoning words and Grade 6 academic vocabulary for learners moving from simple comprehension toward analysis, judgement and independent thinking. It is written for Primary 6, Grade 6, 6th grade and Year 6 students worldwide and teaches the language behind claims, evidence, assumptions, inference, bias, validity, cause and effect, probability, trade-offs, hypotheses, synthesis and evaluation.

Students searching for 6th grade critical thinking vocabulary, Grade 6 reasoning words, evidence vocabulary or academic vocabulary for critical thinking need more than difficult-sounding words. They need a working language for asking: What is the claim? What counts as evidence? Is the source credible? Am I making an assumption? Does the conclusion follow? Is this correlation or causation? How certain am I? What trade-off does this decision create? These words give learners labels for the moves that careful thinking already requires.

This guide therefore treats vocabulary as a toolkit for reading comprehension, writing, mathematics, science, social studies, oral discussion and problem solving. Each term includes a student-friendly meaning, an original example, a boundary showing what the term does not mean, and transfer practice using Alicia, Tricia and Kai Kai. The goal is not to make a Grade 6 student sound like an adult academic. The goal is to help the learner see distinctions clearly enough to reason, explain and decide better.

Scope note: this is an eduKate learning list, not an official prescribed list from Singapore MOE or SEAB, the US Common Core, SATs, Cambridge or any other national or examination authority. Different systems organise critical-thinking skills differently. Use this as a worldwide teaching resource and align it with the learner’s actual curriculum, texts and tasks.

Why critical thinking needs vocabulary

Thinking becomes easier to inspect when it has names. A learner may sense that something is wrong with an argument but be unable to say whether the problem is weak evidence, an unsupported assumption, irrelevant information, a contradiction or a confusion between correlation and causation. Vocabulary turns a vague feeling into a diagnosable distinction.

This does not mean learning the word automatically creates the thinking skill. Knowing the term bias does not guarantee unbiased reasoning, and knowing evidence does not guarantee good evidence use. The vocabulary is a control panel: it helps learners notice the operation, ask a better question, describe the weakness and choose a repair.

Grade 6 curricula and resources increasingly connect comprehension, vocabulary and critical thinking. Public resources for sixth-grade learners also combine vocabulary with problem solving, reasoning, reading comprehension and higher-order questioning. That makes this lane distinct from a generic word list: the search intent is the language of reasoning itself.

How to use the 100 words

1. Name the move. When a learner sees a reasoning problem, choose the word that best describes it: evidence, assumption, bias, cause, risk, trade-off and so on.
2. State the boundary. Explain what the word does not mean. This prevents shallow synonym learning.
3. Apply it to a real task. Use the term while reading, solving, discussing or evaluating.
4. Ask the diagnostic question. “What evidence?” “What assumption?” “How reliable?” “What alternative?”
5. Transfer it. Move the same term into another subject so the concept becomes portable.
6. Review after a delay. Retrieve the term from a situation rather than from an alphabetical prompt.

The first ten distinctions to master

Top 100 Primary 6 / Grade 6 critical-thinking vocabulary at a glance

Claims, evidence and argument | Words 1–10

Reading comprehension: use the vocabulary to interrogate a text

When reading an article, story or source, learners can turn the vocabulary into questions: What is the central claim? Which details are evidence? What assumptions are unstated? Whose perspective is represented? Is there possible bias? What is implied rather than explicit? Which conclusion is justified? What uncertainty remains?

This approach turns comprehension from answer-hunting into model-building. The reader is not only locating information; the reader is examining how the text earns its meaning. Even narrative reading benefits. A character can act on an assumption, a narrator can present a perspective, a plot can create uncertainty, and an ending can force a new interpretation.

Writing: build claims that survive questions

In explanatory and persuasive writing, the critical-thinking vocabulary becomes a drafting checklist. State a claim. Add relevant evidence. Explain the reasoning. Acknowledge a counterargument. Check whether the conclusion is stronger than the evidence allows. Remove irrelevant detail. Clarify the scope. Distinguish fact from interpretation.

The aim is not to insert the vocabulary into every paragraph. The aim is to use the concepts behind the vocabulary. A clear argument may never contain the word premise, yet the writer should still know what the premise is. The words help the learner control the structure even when they remain invisible in the final prose.

Science: separate observation, hypothesis, evidence and conclusion

Science is an ideal place to practise these distinctions. Data are not automatically conclusions. Observations are not the same as interpretations. A hypothesis is testable. A variable can change. A condition defines when a result applies. Reliability and validity ask different questions. Correlation does not automatically establish causation.

Ask learners to label each sentence in a lab write-up: observation, inference, hypothesis, evidence, explanation or conclusion. This exposes category errors immediately. When a learner writes “The plant died because of salt” after one observation, the vocabulary gives a route to repair: Is that a conclusion, an inference or a proven cause? What evidence would be sufficient?

Mathematics: reasoning vocabulary beyond calculation

Mathematics also needs language for critical thinking. A solution rests on assumptions and conditions. A pattern can suggest a rule, but an exception or counterexample can break a generalisation. A model represents a relationship. A proof depends on logic. An estimate carries uncertainty. A decision about method may involve efficiency, constraints and trade-offs.

The strongest question is often not “Did you get the answer?” but “Why is this method valid?” or “Under what condition would this reasoning fail?” The vocabulary makes those questions teachable.

Oral discussion: disagree with the idea, not the person

Critical-thinking vocabulary improves discussion because it gives learners neutral language for disagreement. “I think your evidence is insufficient” is more precise than “That is wrong.” “That conclusion depends on an assumption” targets the reasoning rather than the speaker. “I see the perspective, but the source may be biased” separates viewpoint from evidential quality.

This is a civic skill as well as an academic one. Learners who can name the type of disagreement are less likely to treat every disagreement as personal conflict.

Worksheet 1 model guidance

1. claim: A strong response should preserve this meaning: a statement that someone presents as true, reasonable or worth accepting It should also respect this boundary: A claim needs support; it is not automatically a fact. One model context is: Alicia made the claim that the second route was safer, then looked for evidence.

2. evidence: A strong response should preserve this meaning: information, observations, data or examples used to support or test a claim It should also respect this boundary: Evidence is support for a conclusion; it still needs interpretation. One model context is: Tricia used two details from the passage as evidence for her inference.

3. reason: A strong response should preserve this meaning: an explanation for why something happens or why a choice or belief is justified It should also respect this boundary: A reason explains or supports; it is not the same as evidence in every task. One model context is: Kai Kai gave a reason for choosing the later train.

4. support: A strong response should preserve this meaning: information or reasoning that strengthens a claim, answer or conclusion It should also respect this boundary: Support works only when the connection to the claim is clear. One model context is: Alicia added support by explaining why the quoted detail mattered.

5. example: A strong response should preserve this meaning: a particular case used to illustrate a general idea It should also respect this boundary: An example shows an idea in action but does not by itself prove a broad claim. One model context is: Tricia gave a classroom example of cooperation.

6. counterexample: A strong response should preserve this meaning: an example that shows a rule, claim or generalisation does not always hold It should also respect this boundary: A counterexample challenges a broad claim by meeting the conditions but breaking the conclusion. One model context is: Kai Kai found one counterexample that disproved the proposed rule.

7. premise: A strong response should preserve this meaning: a statement or assumption from which reasoning begins It should also respect this boundary: A premise is a starting point in an argument, not the final conclusion. One model context is: Alicia checked whether the premise of the argument was actually true.

8. conclusion: A strong response should preserve this meaning: a judgement or result reached after considering evidence or reasoning It should also respect this boundary: A conclusion should follow from what came before. One model context is: Tricia wrote a tentative conclusion after reviewing the results.

9. argument: A strong response should preserve this meaning: a connected set of claims, reasons and evidence supporting a position It should also respect this boundary: An academic argument is not simply a quarrel. One model context is: Kai Kai built an argument that linked the claim to relevant evidence.

10. counterargument: A strong response should preserve this meaning: a reasoned position that challenges another argument It should also respect this boundary: A counterargument should address the actual claim rather than a weaker version. One model context is: Alicia considered the strongest counterargument before revising her position.

11. source: A strong response should preserve this meaning: the person, text, organisation, dataset or origin from which information comes It should also respect this boundary: A source provides information; trustworthiness must still be checked. One model context is: Tricia traced the statistic back to its original source.

12. credibility: A strong response should preserve this meaning: the quality of being believable and worthy of trust It should also respect this boundary: Credibility depends on evidence, expertise, transparency and context, not confidence alone. One model context is: Kai Kai checked the author’s credibility before relying on the article.

13. reliability: A strong response should preserve this meaning: the quality of producing dependable or consistent information or results It should also respect this boundary: Reliable does not always mean correct in every case; it means dependable enough for the purpose. One model context is: Alicia compared repeated measurements to judge reliability.

14. validity: A strong response should preserve this meaning: the quality of being sound, appropriate or well-founded for the intended conclusion It should also respect this boundary: A result can be reliable yet still invalid if it measures the wrong thing. One model context is: Tricia asked whether the test had validity for the skill it claimed to measure.

15. accuracy: A strong response should preserve this meaning: the degree to which something is correct or close to the true value It should also respect this boundary: Accuracy concerns correctness, while precision can concern exactness or repeatability. One model context is: Kai Kai checked the accuracy of the calculation with another method.

16. relevance: A strong response should preserve this meaning: the degree to which information is connected to the question or purpose It should also respect this boundary: A fact can be true but irrelevant to the task. One model context is: Alicia removed a detail that had little relevance to her main point.

17. sufficiency: A strong response should preserve this meaning: the state of being enough for a particular purpose It should also respect this boundary: Sufficient evidence means enough evidence, not every possible piece of evidence. One model context is: Tricia asked whether one example provided enough sufficiency for the broad claim.

18. bias: A strong response should preserve this meaning: a tendency that unfairly or systematically favours one side, outcome or interpretation It should also respect this boundary: Bias can affect selection, wording, measurement or judgement. One model context is: Kai Kai noticed possible bias in a survey that sampled only one group.

19. objectivity: A strong response should preserve this meaning: the effort to judge using observable information and explicit standards rather than personal preference alone It should also respect this boundary: Objectivity does not mean having no perspective; it means controlling personal preference in the judgement. One model context is: Alicia used clear criteria to increase objectivity.

20. perspective: A strong response should preserve this meaning: a particular way of seeing or understanding an issue shaped by position, experience or purpose It should also respect this boundary: Different perspectives can be reasonable without all claims being equally supported. One model context is: Tricia considered the issue from the resident’s perspective.

21. inference: A strong response should preserve this meaning: a conclusion reached from clues and prior knowledge rather than a direct statement It should also respect this boundary: An inference should be supported by clues, not guessed freely. One model context is: Kai Kai made the inference that the character was anxious from repeated glances at the clock.

22. deduction: A strong response should preserve this meaning: a conclusion reached by reasoning from known facts, rules or premises It should also respect this boundary: Deduction depends on the logic connecting the starting information to the result. One model context is: Alicia used deduction to work out the missing condition.

23. assumption: A strong response should preserve this meaning: an idea accepted as true for the moment, sometimes without complete proof It should also respect this boundary: An assumption may be useful, but it should be noticed and checked when important. One model context is: Tricia realised that her first plan depended on an untested assumption.

24. implication: A strong response should preserve this meaning: a meaning, consequence or conclusion suggested by information even when not directly stated It should also respect this boundary: An implication is what follows or is suggested, not necessarily what was explicitly said. One model context is: Kai Kai discussed the implication of the new rule for younger students.

25. interpretation: A strong response should preserve this meaning: an explanation of the meaning or significance of information, language or events It should also respect this boundary: A strong interpretation fits the evidence and context. One model context is: Alicia offered an interpretation of the final scene and cited details.

26. explanation: A strong response should preserve this meaning: an account that makes how, why or what something means clearer It should also respect this boundary: An explanation connects parts causally or logically rather than merely repeating them. One model context is: Tricia gave an explanation for why the graph changed.

27. logic: A strong response should preserve this meaning: the structure of reasoning that connects statements, evidence and conclusions It should also respect this boundary: Good logic concerns whether the steps follow, not whether the conclusion is popular. One model context is: Kai Kai checked the logic of the argument before accepting it.

28. reasoning: A strong response should preserve this meaning: the process of using information, rules and relationships to reach a conclusion It should also respect this boundary: Reasoning makes the path from evidence to answer visible. One model context is: Alicia showed her reasoning instead of writing only the final answer.

29. consistency: A strong response should preserve this meaning: the quality of remaining in agreement with a rule, pattern, standard or earlier result It should also respect this boundary: Consistency supports confidence, but repeated error can also be consistent. One model context is: Tricia checked whether the pattern showed consistency across all trials.

30. contradiction: A strong response should preserve this meaning: a conflict between statements, facts or claims that cannot all be true in the same way at the same time It should also respect this boundary: A contradiction is stronger than a mere difference. One model context is: Kai Kai found a contradiction between the summary and the data table.

Worksheet 3: evidence ladder

For each claim below, write four levels of support: (1) no support, (2) weak example, (3) relevant evidence, and (4) relevant evidence plus reasoning. Then label what changes at each level.

1. “The new school route is safer.”
2. “Retrieval practice helps vocabulary learning.”
3. “The character is hiding something.”
4. “The second method is more efficient.”
5. “The survey result represents the whole class.”
6. “The graph shows a meaningful change.”
7. “This website is a credible source.”
8. “The proposed solution is fair.”
9. “The two variables are causally connected.”
10. “The conclusion is valid.”

The exercise teaches a crucial distinction: adding more words is not the same as adding better support. Evidence quality, relevance, sufficiency and reasoning all matter.

Worksheet 4: correlation or causation?

1. 1. Students who read more books also tend to know more vocabulary. Decide whether the statement shows correlation only, stronger evidence for causation, or insufficient information. State what extra evidence would increase confidence.
2. 2. On hotter days, more ice cream is sold and more people visit swimming pools. Decide whether the statement shows correlation only, stronger evidence for causation, or insufficient information. State what extra evidence would increase confidence.
3. 3. After the school added a shaded walkway, fewer students reported arriving soaked during rain. Decide whether the statement shows correlation only, stronger evidence for causation, or insufficient information. State what extra evidence would increase confidence.
4. 4. A plant grew faster after receiving more light while other important conditions were controlled. Decide whether the statement shows correlation only, stronger evidence for causation, or insufficient information. State what extra evidence would increase confidence.
5. 5. People who exercise regularly often report better health. Decide whether the statement shows correlation only, stronger evidence for causation, or insufficient information. State what extra evidence would increase confidence.
6. 6. A class scored higher after a new study method, but the test was easier than the previous one. Decide whether the statement shows correlation only, stronger evidence for causation, or insufficient information. State what extra evidence would increase confidence.
7. 7. A medication group improved more than a comparison group in a controlled trial. Decide whether the statement shows correlation only, stronger evidence for causation, or insufficient information. State what extra evidence would increase confidence.
8. 8. Two towns with more libraries also have higher reading scores. Decide whether the statement shows correlation only, stronger evidence for causation, or insufficient information. State what extra evidence would increase confidence.

There is not always one automatic answer from a single sentence. The learner’s job is to identify what the design does and does not justify. This is exactly why the distinction between correlation, causation, confounding factors and uncertainty matters.

A four-week critical-thinking vocabulary plan

Week 1 — claims, evidence and trust

Learn claim, evidence, reason, premise, conclusion, source, credibility, reliability, validity and relevance. Use real reading passages. Ask learners to label each sentence and explain the boundary between the concepts.

Week 2 — inference, cause and uncertainty

Practise inference, assumption, implication, logic, cause, effect, correlation, causation, possibility, probability and uncertainty. Use short scenarios in which the learner must decide how strong a conclusion is justified.

Week 3 — systems, criteria and decisions

Work with system, structure, function, process, constraint, criterion, standard, priority, trade-off, risk, alternative, strategy and solution. Apply the terms to real planning problems where choices have consequences.

Week 4 — synthesis, evaluation and metacognition

Bring together synthesis, evaluation, judgement, reflection, metacognition, revision and transfer. Ask learners to inspect their own reasoning: What did I assume? What evidence changed my mind? How confident am I? What would I revise? Can I use this thinking pattern elsewhere?

For parents

Use the vocabulary during ordinary decisions. When choosing between two routes, ask about criteria, risk and trade-offs. When reading a news story, ask about source, evidence and credibility. When a child is certain, ask what evidence supports that confidence. These conversations make the words useful without turning home into a formal lesson.

For teachers and tutors

Teach the words beside the reasoning routines. Put claim → evidence → reasoning on the board during writing. Put observation → inference → conclusion beside science work. Put pattern → hypothesis → counterexample beside mathematics. The vocabulary becomes durable when it repeatedly controls real thinking.

When marking, diagnose the concept rather than writing only “think deeper.” Say “Your claim is clear but the evidence is insufficient,” “You have correlation but not enough evidence for causation,” or “Your conclusion is stronger than the data justify.” Specific vocabulary makes feedback executable.

Frequently asked questions

What is critical-thinking vocabulary?

It is the language used to name reasoning moves, evidence quality, uncertainty, relationships, decisions and evaluation.

Does knowing the words automatically improve critical thinking?

No. The words help learners notice and discuss reasoning, but the concepts must be practised in real tasks.

Why teach these words in Primary 6 or Grade 6?

At this stage, learners increasingly meet abstract texts, multi-step problems, source evaluation and questions that require evidence and judgement.

What is the most important word on the list?

There is no single winner, but claim, evidence, reason, assumption, inference, relevance and conclusion form a useful starting network.

What is the difference between fact and evidence?

A fact can be true yet irrelevant. Evidence is information used to support or test a particular claim.

What is the difference between reliability and validity?

Reliability concerns dependability or consistency. Validity concerns whether the method or conclusion is sound for its intended purpose.

What is the difference between bias and perspective?

Perspective is a viewpoint shaped by position or experience. Bias is a systematic tendency that can distort selection or judgement.

What is the difference between possibility and probability?

Possibility means an event can happen; probability concerns how likely it is.

What is the difference between correlation and causation?

Correlation means two things vary together. Causation means one factor helps produce change in another.

What is the difference between a model and a theory?

A model is a representation used to explain or predict selected features. A theory is a broader explanatory framework supported by evidence and reasoning.

Should students memorise definitions?

Definitions help, but students should also apply the terms to arguments, experiments, decisions and reading tasks.

How many terms should be taught at once?

Five to ten connected terms are enough for deep work. Recycle them across several subjects before adding more.

Can these words support writing?

Yes. They help students structure claims, select evidence, qualify conclusions and revise reasoning.

Can these words support mathematics?

Yes. Terms such as assumption, pattern, counterexample, validity, model, condition and generalisation are central to mathematical reasoning.

Can these words support science?

Yes. Observation, hypothesis, data, evidence, variable, reliability, validity, causation and conclusion are especially useful.

How do we know a learner owns the vocabulary?

The learner can define the term, distinguish it from near-neighbours, use it to diagnose a real reasoning situation and transfer it to another subject.

Final principle: better distinctions produce better thinking

Critical thinking is not a collection of impressive words. It is the habit of making distinctions that matter. Claim is not evidence. Correlation is not causation. Possible is not probable. Perspective is not automatically bias. Reliable is not automatically valid. Data are not automatically conclusions.

When a Primary 6 or Grade 6 learner can name those distinctions, the learner gains a practical advantage: reasoning becomes visible enough to inspect and repair. That is the purpose of this vocabulary list.
