Critical thinking is the ability to examine information, ask useful questions, compare possible explanations and reach a reasoned conclusion. It is not about being argumentative, suspicious of everything or always finding the correct answer immediately.
Children use critical thinking when they decide whether an online claim is trustworthy, explain why a character behaved in a particular way, test different solutions to a practical problem or change their mind after seeing better evidence.
These skills develop gradually. Parents and teachers can support them by creating regular opportunities for children to explain their reasoning, make manageable decisions and reflect on mistakes without feeling embarrassed.
Why critical thinking matters
Children encounter a large amount of information through lessons, conversations, advertising, social media, videos and online searches. Being able to remember facts is useful, but they also need to judge whether information is reliable and understand how different ideas connect.
Critical thinking can help children:
- solve unfamiliar problems rather than depend only on memorised steps;
- distinguish evidence from opinion or persuasion;
- recognise when information is incomplete;
- understand perspectives different from their own;
- explain and defend a conclusion;
- change their view when stronger evidence appears;
- make more considered everyday decisions.
These abilities support school subjects, but their value extends beyond examinations. They help young people make choices about friendships, money, health, media and future education.
Encourage children to explain their thinking
Questions that require only a yes, no or one-word answer provide limited insight into how a child reached a conclusion. Open questions encourage them to organise their thoughts and make their reasoning visible.
Instead of asking, “Did you enjoy the story?”, try asking:
- “Why do you think the character made that choice?”
- “Which part changed your opinion?”
- “What might have happened if they had chosen differently?”
- “What evidence supports your answer?”
- “Is there another possible explanation?”
Give children time to respond. Adults sometimes answer their own question when a child pauses, but that pause may be the moment in which the child is forming an idea.
Avoid turning every conversation into a test. The purpose is not to catch mistakes but to understand the child’s thinking and help them develop it.
Use follow-up questions instead of correcting immediately
When a child gives an inaccurate or incomplete answer, adults often provide the correction straight away. Sometimes this is necessary, but a follow-up question may help the child notice the problem independently.
You might ask:
- “How did you work that out?”
- “Does that fit with what we already know?”
- “What could we check?”
- “Would that always be true?”
- “Can you think of an example where it would not work?”
This approach teaches children that an answer can be examined and improved. It also reduces the fear of being wrong, which can otherwise discourage pupils from attempting difficult questions.
When a child changes their mind after reconsidering the evidence, treat that as progress rather than inconsistency. Revising a conclusion is an important part of thoughtful reasoning.
Let children solve everyday problems
Family life provides frequent opportunities for practical thinking. Children can compare options, anticipate consequences and test solutions without needing a formal worksheet.
Depending on their age, they might help decide:
- how to divide pocket money between spending and saving;
- what to pack for a day with uncertain weather;
- how to organise homework around a club;
- which ingredients can replace something missing from a recipe;
- how to arrange furniture in a limited space;
- which travel route is most practical;
- how to resolve competing plans with friends.
Instead of solving the problem immediately, ask the child to suggest two or three options. Discuss the likely advantages, disadvantages and consequences of each.
Younger children may need the choices narrowed. Older pupils can take more responsibility, including experiencing the manageable consequences of a decision that does not work perfectly.
Use books, films and conversations
Stories allow children to examine decisions and consequences without the discussion feeling personally threatening. A character’s behaviour can become a starting point for thinking about motives, fairness, evidence and alternative viewpoints.
After reading or watching something together, ask:
- What did the character want?
- Why might another character see the situation differently?
- Was the decision fair?
- What information was the character missing?
- Could the ending have been avoided?
- Which character changed most, and why?
There does not need to be one agreed interpretation. Children can learn that two people may reach different conclusions while both using reasonable evidence.
Family discussions can also involve ordinary topics, such as whether school uniform is helpful, whether homework should be shorter or whether children should have later bedtimes during holidays. Encourage children to argue more than one side rather than defending only their first opinion.
Teach children to evaluate online information
Children can access information quickly, but search results, videos and social posts do not all deserve equal trust. Critical thinking online involves checking the source, evidence, date and purpose of a claim.
When looking at an online article or video, ask:
- Who created this?
- What might they want the audience to believe or do?
- Do they provide evidence?
- Can the claim be confirmed elsewhere?
- Is the information current?
- Does the headline accurately represent the content?
- Could important context be missing?
Explain the difference between a claim becoming popular and becoming true. A large number of views, likes or shares does not confirm accuracy.
Advertising and sponsored content also provide useful examples. Discuss how language, images, testimonials and limited-time offers are designed to influence decisions.

Make room for mistakes and revision
Children are less likely to think independently when every mistake produces embarrassment, criticism or an immediate adult takeover. Critical thinking requires the freedom to try an idea, observe what happens and adjust the plan.
If a model collapses, a recipe fails or a homework approach does not work, ask what the child noticed. Consider which part of the plan was successful and which assumption needs to change.
Useful questions include:
- “What did you expect to happen?”
- “What actually happened?”
- “Where do you think the plan changed?”
- “What would you try next time?”
Adults can model this attitude by acknowledging their own mistakes. Saying, “I assumed the journey would take twenty minutes, but I did not allow for traffic” demonstrates reflection more effectively than pretending adults always decide correctly.
Praise the process rather than only the outcome. Notice when a child checks evidence, considers another view or persists with a difficult problem.
Use games and practical activities
Games can develop reasoning when children must plan ahead, recognise patterns, remember information or respond to another player’s decisions.
Useful activities include:
- chess, draughts and strategy board games;
- puzzles and logic problems;
- construction challenges using bricks or craft materials;
- coding and debugging activities;
- science experiments;
- cooking and recipe adaptation;
- mystery or deduction games;
- designing and testing paper bridges, towers or vehicles.
The adult does not need to provide constant instruction. Ask the child to predict what may happen, explain their strategy and evaluate the result afterwards.
Clubs can provide further opportunities to practise these skills collaboratively. How Clubs and After-School Activities Boost Learning explains how coding, debate, sport, drama and other activities can support wider development.
Balance guidance with independence
Children need enough support to engage with a problem, but too much help can remove the thinking. Adults may need to resist the urge to prevent every delay, wrong turn or minor frustration.
A useful approach is to offer the smallest prompt that allows the child to continue. Instead of providing the answer, you might restate the question, identify the next step or remind them of a similar problem.
As the child becomes more confident, reduce the support. This gradual transfer of responsibility helps children learn that difficulty is not a signal to stop or wait for an adult.
However, independence should remain appropriate to the child’s age and needs. A pupil with working-memory, language or attention difficulties may understand the reasoning task but need instructions broken down or presented visually.

How schools can develop critical thinking
Critical thinking should not be confined to occasional debates or special projects. It can be developed across mathematics, science, history, English, art and other subjects.
Teachers can support it by asking pupils to:
- explain how they reached an answer;
- compare different methods;
- identify evidence for a claim;
- question the reliability of a source;
- predict outcomes before testing them;
- evaluate which solution is most effective;
- respond constructively to another pupil’s reasoning;
- reflect on why an approach succeeded or failed.
Group work can expose pupils to different perspectives, but it needs structure. Without clear roles and expectations, one child may do all the thinking while others agree passively.
Teachers should also create an atmosphere in which pupils can ask questions without appearing difficult or disrespectful. Teaching Pupils to Ask Better Questions provides practical strategies for developing this classroom culture.
The article The Science of Explanation: Why Pupils Don’t Just “Get It” explores how clear explanations and checks for understanding can support deeper learning.
Avoid common mistakes when encouraging critical thinking
One common mistake is treating critical thinking as constant scepticism. Children should question claims, but they should also learn how to recognise credible expertise and strong evidence.
Another is asking broad questions without providing enough knowledge. Children cannot reason well about a subject they know nothing about. Critical thinking depends partly on having relevant facts, vocabulary and examples available.
Adults may also accidentally reward only confident answers. A quieter child who thinks carefully may need more time than someone who responds immediately. Speed should not be confused with depth.
Avoid making every conversation competitive. The goal is not for the child to defeat another person in an argument. Good reasoning includes listening, acknowledging uncertainty and identifying valid points on more than one side.
Finally, do not expect children to challenge every family instruction. Adults can explain that some decisions are open for discussion while others involve safety, law or parental responsibility.
Frequently asked questions
At what age can children develop critical thinking?
Critical thinking begins in simple forms during early childhood. Young children can compare objects, predict what may happen and explain basic choices. The complexity of the questions and evidence should increase gradually with age.
Is critical thinking the same as intelligence?
No. Intelligence, knowledge and critical thinking are related but not identical. A knowledgeable child may still accept weak claims without checking them, while another child may use careful reasoning even when they do not know every fact.
Can critical thinking be taught?
Yes, but it develops through repeated practice rather than one isolated lesson. Children need opportunities to explain reasoning, compare evidence, solve problems and reflect on mistakes across different subjects and situations.
Does questioning adults show critical thinking?
Sometimes. Asking for reasons or evidence can be thoughtful, but disagreement alone is not critical thinking. Children also need to listen, evaluate the answer and recognise when an adult has responsibility for a safety or family decision.
How can I help a child who always says “I don’t know”?
Reduce the size of the question and offer thinking prompts rather than the answer. Ask what they noticed first, provide two possible starting points or allow extra time. Fear of being wrong may be as important as lack of understanding.
Are puzzles enough to develop critical thinking?
Puzzles can strengthen logic and problem-solving, but children also need to evaluate real information, discuss different perspectives and apply reasoning in unfamiliar situations.
Should parents correct misinformation immediately?
Serious or harmful misinformation should be corrected clearly. In lower-risk situations, parents can first ask how the child knows, what evidence exists and how the claim could be checked. This helps develop a process the child can use independently.
How can teachers assess critical thinking?
Teachers can examine pupils’ explanations, use of evidence, comparison of methods and ability to revise conclusions. The reasoning process often reveals more than whether the final answer is correct.
Can children think critically without strong subject knowledge?
Only to a limited extent. General reasoning skills help, but children need relevant facts and vocabulary to evaluate a topic properly. Teaching knowledge and teaching children how to use that knowledge should work together.
What is the simplest way to encourage critical thinking at home?
Ask children to explain how they reached a conclusion and listen before offering your own answer. Everyday questions such as “What makes you think that?” and “How could we check?” can gradually build stronger reasoning habits.
