Guide contents
1–5: Meanings and everyday use
6–10: More examples, questions and sources
“What makes you think that?” is a useful question when it comes with time to answer. A ten-year-old might use claim to describe what someone said, support to explain the reasons offered, and uncertainty to name what remains unresolved. The words make a conversation easier to examine.
Here, Age 10 means 120–131 months. The 200 entries are editorial selections for exploring science, society, relationships and the wider world. They are not a validated ranking, a curriculum, a required vocabulary size or a deadline for mastery. Specialist words such as cytoplasm, aquifer and viscosity can remain words to encounter with support when they become relevant.
Each target has one place in this series’ age tables. Conversation should freely reuse earlier vocabulary: an explanation of a consequence still needs familiar words such as because, before and after. Examples may also include useful words outside the selected 200.
Choose a question that has a purpose. Why did a plan change? Does this description fit the picture? Who is responsible for a shared task? The activities below offer possible ways in. All worked scenes are hypothetical, not reports of learning outcomes.
Some words are most useful beside a neighbouring word. The aim is to explain the difference in a particular situation, then notice when that difference matters elsewhere.
Eight vocabulary contrasts for clearer thinking and conversation
| Words | A starting explanation | A useful question |
|---|---|---|
| Claim / assumption | A claim is a statement someone puts forward as true. An assumption is something being treated as true without establishing it in that situation. | “What was said, and what are we taking for granted?” |
| Cause / effect | A cause helps bring something about. An effect is a result. An event can have several contributing causes. | “What might have produced this change?” |
| Comparison / contrast | A comparison examines things alongside each other. A contrast draws attention to differences. | “Which feature are we comparing?” |
| Scarcity / abundance | Scarcity means something is in short supply relative to what is needed or wanted. Abundance means there is a plentiful amount. | “Enough of what, for whom, and for how long?” |
| Responsibility / accountability | Responsibility can mean having a task or duty. Accountability means being answerable for what you do about it. | “Who agreed to do it, and how will we explain what happened?” |
| Empathy / compassion | Empathy involves trying to understand another person’s experience. Compassion includes concern for someone’s difficulty and a wish to help. | “What might they be experiencing, and what help would they welcome?” |
| Destination / itinerary | A destination is a place you intend to reach. An itinerary sets out the route or planned events of a journey. | “Do we know only where we are going, or also the plan?” |
| Context / perspective | Context is the surrounding information that helps explain something. Perspective is the position or point of view from which it is considered. | “What background do we need, and whose view are we hearing?” |
Use these as working explanations. If a new example does not fit, investigate the word’s fuller meaning together. For instance, support can mean evidence for a claim, help for a person, or something holding a structure up. The surrounding sentence tells you which use is intended.
The Australian Bureau of Statistics explains that a statistical relationship does not, by itself, establish cause and effect. Two things occurring together can prompt a question without settling its answer.
Hypothetical claim: the lucky caps
Child: “We wore matching caps and won. The caps made us win.”
Adult: “That is a claim about the cause. What else was different?”
Child: “We practised more this time.”
Adult: “Could that matter? Were the opponents and the game the same?”
Child: “No, it was a different team.”
The information given does not establish which factor mattered. A more careful sentence is, “We won while wearing the caps, but we do not know that the caps caused the victory.” That is a useful revision, not a failure to answer.
Ask what evidence would help distinguish the possible explanations. Avoid presenting one extra example as automatic proof. An observation may offer support while still leaving uncertainty.
When reading history, a chronology can show which event came first. Explaining why the next event happened requires a further argument. Invite your child to mark where the writer moves from reporting events to explaining a cause.
When drops appear outside a cold drinking glass, ask where the water came from. Separate the observation from an explanation you have not checked, such as a leak.
The US Geological Survey describes condensation as water vapour changing into liquid water and uses the outside of a cold glass as an example. Evaporation is the change in the other direction. These names describe processes; they do not mean that water has simply appeared from nowhere or disappeared entirely.
Hypothetical conversation: revising an explanation
Child: “The water came through the glass.”
Adult: “That is one explanation to consider. The source describes water vapour in the air becoming liquid on a cold surface.”
Child: “So the drops can come from the air?”
Adult: “Yes. That process is condensation. Which part of our first explanation should we change?”
For another topic, use a labelled diagram rather than trying to reproduce the whole process. Locate a nucleus in an appropriate cell diagram, or identify where an aquifer is shown in a landscape. Ask what the picture represents and which details it leaves out.
Allow a simple explanation before requesting a technical one. “Water vapour becomes liquid” may be enough for the present conversation. Several accurate sentences connected together are more useful here than a list of impressive terms with no clear relationship.
When a book mentions a parliament, cabinet, court or jury, first ask which country and period it describes. These words should not become a single imaginary system assumed to operate everywhere.
For a specific example, UK Parliament distinguishes Parliament from the Government. Its explanation places the Cabinet within the Government and describes Parliament’s work in lawmaking and examining government decisions. That gives cabinet, minister and parliament different jobs in the same explanation.
In another named setting, the US Courts website describes trial juries that return verdicts in federal cases, while distinguishing them from grand juries with another role. This is an example from the United States federal system, not a statement that every court or country uses juries.
Hypothetical reading conversation
Child: “Does the cabinet mean everybody in parliament?”
Adult: “In this UK explanation, it means senior government ministers. Let’s keep the two labels separate.”
Child: “So I need to know which system the book means?”
Adult: “Yes. We can put the country beside our notes.”
Use a small role table if it helps: name of institution, place described, and role stated by the source. Leave an entry open when you cannot verify it. A classroom vote can illustrate choosing between options, but it does not reproduce all the rules of a national election.
A real or imaginary journey can connect destination, itinerary, accommodation, reservation and excursion. Make the plan small enough to explain: a visit to a museum and a meal, for example. An excursion is a short trip or outing; it need not involve an international holiday.
Hypothetical planning task: two different itineraries
One person wants to spend the whole afternoon at a museum. Another wants a short museum visit followed by a walk. Ask the child to make a comparison: which plan gives more time indoors, which involves more walking, and which better fits the group’s wishes?
A justification should refer to the actual decision: “This itinerary leaves time for Grandpa to sit down” explains why that feature matters. “It is the best” gives the listener much less information.
When discussing cuisine, custom, tradition, festival or ritual, attach the description to the people or occasion your source actually describes. Prefer “This family celebrates by…” to a sweeping claim about everyone in a country. Ask a willing person how they describe their own practice, and accept that one answer does not speak for everybody.
Keep heritage and ancestry distinct in conversation. Ancestry concerns family descent. Heritage can include valued things received from the past, such as places, practices and stories. Invite a family member to choose a story they want to share; the child does not need to disclose private family information to complete a vocabulary activity.
Words such as consent, boundary, responsibility and collaboration can help someone state what they want and understand what others want. Explain the particular action involved instead of asking for an abstract definition first.
Hypothetical conversation: sharing a drawing
Child: “Can I show your drawing to the group?”
Friend: “You can show this one, but not the page underneath.”
Adult: “You asked for consent to share it. Your friend agreed to one drawing and set a boundary around the other.”
Child: “I’ll keep the second page covered.”
Here, consent means agreement to the stated action. If the proposed action changes, ask again. A boundary can be expressed concretely: “Please ask before borrowing this,” or “I want to finish speaking.” Discuss how everyone can respect it in the situation.
For accountability, use a repairable example. Someone agreed to bring the materials but forgot. They can explain what happened, acknowledge the effect on the group and help arrange a replacement. Avoid using the word merely as a grander label for blame.
Give empathy room for uncertainty: “I wonder whether they felt left out” leaves space to ask. “I know exactly how they feel” may close that space. An offer of help can also be specific: “Would you like me to explain the instructions with you?” Let the answer influence what happens next.
Select one activity when it fits the day. This menu is illustrative, with no prescribed number of words or sessions.
- Inspect a claim: write what is being said, the support offered and one question that remains.
- Explain a process: use a picture or ordinary observation to connect a scientific word with what happens.
- Compare plans: describe two possible itineraries and justify a preference using the group’s needs.
- Clarify a shared task: agree who is responsible for what and how the group will check progress.
A useful note might read: “I thought the cabinet meant all of parliament. In the UK example, it means senior government ministers.” That records a change in understanding. It is more informative than a tick beside cabinet.
Revisit the word when a new context makes it useful. Does context help explain a historical photograph? Does uncertainty describe what remains unknown in an investigation? Can the child offer a justification that actually addresses a question?
Welcome explanations in the language that lets your child express the idea most clearly. You can connect an English term to that explanation afterwards. Keep room for questions, corrections and “I do not know yet”; none of those responses requires abandoning the conversation.
Should a ten-year-old master every specialist word here?
No. The selection includes possible stretch vocabulary, not a universal expectation. Choose a useful entry and give it an accurate context. A brief encounter with a diagram or explanation can be enough for now.
How can I tell whether a word is becoming useful?
Look for what it helps the child do: explain a distinction, ask a clearer question, revise a mistaken claim or make a request. Record the example and the support given, rather than declaring permanent mastery after one correct answer.
Must we avoid repeating words from earlier ages?
No. Only the target tables avoid repeated entries. Useful words should return throughout conversations and reading. An explanation would become awkward if earlier vocabulary were forbidden.
What if a child uses a word confidently but inaccurately?
Ask for the intended meaning, then compare it with the example or source. “Show me which part you mean” can reveal the misunderstanding. Offer a clearer sentence and give the child room to revise theirs.
Can we learn these words without travel or special equipment?
Yes. A library book, photograph, labelled diagram, family story or invented planning problem can provide a context. Choose material that makes the meaning clear; the activity does not need to be expensive or elaborate.
The word selection, contrasts, activities and dialogues are original editorial suggestions. These primary sources support the specified factual explanations; they do not validate the 200-word selection or prescribe a developmental timetable.
- Australian Bureau of Statistics: Correlation and Causation — a relationship alone does not establish a cause.
- US Geological Survey: Condensation and the Water Cycle — water vapour becoming liquid, including on a cold glass.
- UK Parliament: Parliament and the Government — distinct institutional roles in the United Kingdom.
- US Courts: Types of Juries — trial and grand juries in the US federal system.
