Children make comparisons all day: which book to borrow, which route to take, which club to join or how to spend saved money. Arguments often become “this one is better” versus “no, that one is.” A fair comparison does not remove preference. It gives both options the same questions so the preference can be understood.
This works best for low-stakes, genuinely available choices. Adults should still set limits around safety, cost and family commitments. The child’s job is not to negotiate every boundary; it is to practise noticing criteria, evidence and trade-offs within an honest choice.
Start with a clear decision
Write one sentence: “We are choosing between ___ and ___ for ___.” Check that the two options solve the same problem. Comparing a bicycle with a video game makes sense only if the decision is how to use a budget; it does not make sense if the goal is transport.
Then name any non-negotiables before scoring. For example: both choices must fit the budget, be safe for the child’s age and work with the available time. An option that fails a true requirement is not rescued by a high total later.
Choose three or four criteria
Criteria are the features that matter. Ask, “What would make this choice work well for us?” For two after-school activities, criteria might be enjoyment, travel time, cost and opportunity to be with friends. For two project ideas, they might be available materials, time, interest and how clearly the result can be explained.
Let the child suggest criteria, but test each one:
- Does it matter to the goal?
- Can we use it for both options?
- Can we find some evidence, or is it only a guess?
- Is it secretly the same as another criterion?
Avoid so many criteria that the table becomes arithmetic homework. Three is often enough.
Build the same-questions table
| Criterion | Option A | Option B |
|---|---|---|
| Cost | What will it cost in total? | What will it cost in total? |
| Time | How much time will it need? | How much time will it need? |
| Enjoyment | What makes us think it will be enjoyable? | What makes us think it will be enjoyable? |
Use words, symbols or a simple 1–3 scale. The numbers do not turn opinions into facts; they merely make reasoning visible. Always ask what evidence sits behind a score. “I gave it three because I tried it last term” is different from “I saw a colourful advert.”
Look for missing information
Circle any cell based mainly on a guess. Decide whether the information is worth finding: check a timetable, ask about equipment, read an independent description or try a small sample. Sometimes the right conclusion is, “We cannot compare this fairly yet.”
Also check for unequal treatment. Did the child list every disadvantage of the less-preferred option but only benefits of the favourite? Invite them to name one strength and one limitation of each. This is not forced balance; it is a check against selective attention.
Make trade-offs explicit
Two reasonable people can use the same information and choose differently because they value criteria differently. Ask, “Which criterion matters most this time, and why?” A longer journey may be acceptable for a much-loved activity; a lower cost may matter more when money is tight.
For younger children, use picture cards and move a token toward the option that does better on each criterion. For older children, let them weight a criterion as “important” or “very important,” but avoid pretending that a complicated formula guarantees the right decision.
Finish with a checkable explanation
Invite a two-sentence conclusion: “I choose A because it fits the budget and I can attend every week. B looks exciting, but the travel time is too long.” Then ask, “What new information could change your mind?” That last question keeps the decision open to evidence without making the child indecisive.
Reserve bigger emotional, health or safety decisions for adult guidance and appropriate professionals. For an older child facing a more consequential choice, use the teen decision-making framework. You can also practise the questioning habit with five everyday critical-thinking questions.
