Child-friendly Probability vocabulary
Child-friendly definitions and examples for words such as chance, outcome, likely, unlikely, certain, impossible and fair.
Quick answer
Probability vocabulary helps us talk about how likely things are to happen. Words like chance, outcome, likely, unlikely, certain, and impossible help us describe what might happen in games, weather, or daily life.Learning outcome
By the end of this page, you will understand how to use probability words to describe what might happen in everyday situations and games. Success signs:- You can explain what "likely" and "unlikely" mean
- You can sort events from "certain" to "impossible"
- You can describe the chance of something happening using words like "chance" and "outcome"
- You can play a game using probability vocabulary
Why this matters
Probability words help us make smart choices and understand what might happen. When you know the chance of rain, you can decide whether to take an umbrella. When you play board games, probability words help you think about what might happen next. Understanding probability vocabulary is useful for science, cooking, sports, and even deciding what to wear!How it works
Probability vocabulary describes how likely something is to happen. We use words like:- Chance – how likely something is to happen
- Outcome – what happens when you do something
- Likely – something that usually happens
- Unlikely – something that doesn’t happen often
- Certain – something that always happens
- Impossible – something that never happens
- Fair – when everyone has the same chance
Examples you can see
Let's look at simple examples to understand these words: Chance – If you roll a dice, there is a chance you might get a 6. The chance is small but possible. Outcome – If you flip a coin, the outcomes are heads or tails. Likely – It is likely that you will wake up in the morning. Unlikely – It is unlikely that you will find a gold coin on the street. Certain – It is certain that you will grow taller as you get older. Impossible – It is impossible for you to fly without wings. Fair – If you and your friend share a pizza equally, that is fair.Try it as a mini adventure
Adventure: The Probability Detective You are a detective solving a mystery! You need to sort clues using probability words. 1st time: You look at the weather forecast. It says it will rain. Is this likely or unlikely? 2nd time: You look in your pocket. You have a coin. What are the outcomes of flipping it? 3rd time: You see a bird flying in the sky. Is it certain, likely, unlikely, or impossible that it will fly? 4th time: You look at your birthday cake. There are 12 candles. Is it certain, likely, unlikely, or impossible that it is your birthday? 5th time: You are playing a dice game. You roll a 6. Is it possible or impossible to roll a 7 on a standard dice?Common mistakes
- Mistake: Thinking that "likely" means "certain"
Why it happens: Children confuse words that sound similar.
Fix: Remember, something "likely" happens often, but not always. - Mistake: Saying that "impossible" means "rare"
Why it happens: Children mix up the meaning of words.
Fix: "Impossible" means it will never happen, no matter how many times you try. - Mistake: Confusing "fair" with "equal"
Why it happens: The word "fair" is used in many ways.
Fix: "Fair" means everyone has the same chance, not just the same amount.
Parent and carer guide
Parents can help by:- Playing probability games with their child at home
- Using probability words in everyday conversations
- Encouraging children to describe what they think will happen in a game
- Practising sorting events from certain to impossible
- Using real-life examples like weather or school events
- "What do you think will happen if we roll the dice?"
- "Is it likely that we will get a head?"
- "What are the possible outcomes of this game?"
- Children might mix up words at first – this is normal
- They may not get all the words right at once – that's okay
- They may not understand all words immediately – that's how learning works
