Zoo maths quest: probability
A story-led junior maths adventure using animal counts, feeding plans and habitat maps to talk about likely, unlikely, certain and impossible events.
Quick answer
Probability is about how likely something is to happen – from certain to impossible – and we can use words like "likely", "unlikely", "certain", and "impossible" to describe events in our daily lives.
Learning outcome
By the end of this page, you will be able to describe events using probability words like "certain", "impossible", "likely", and "unlikely", and understand how to think about chance in real-life situations.
- You can sort events from most likely to least likely.
- You can explain why some events happen more often than others.
- You can use words like "certain", "impossible", "likely", and "unlikely" to describe your own experiences.
- You can make predictions about what might happen next in a game or story.
Why this matters
Probability helps us understand the chances of things happening. Whether you're planning a picnic, guessing who will win a game, or wondering if it will rain tomorrow, probability helps us think about what might happen. In real life, we use probability all the time – like when we say, "It's likely to rain today" or "It's impossible for me to be taller than my dad". Understanding probability helps us make better decisions and predictions.
How it works
Probability is about how sure we are that something will happen. We can think of it in simple ways:
- Certain – This will definitely happen.
- Impossible – This will never happen.
- Likely – This will probably happen.
- Unlikely – This might happen, but not very often.
Let’s imagine a zoo adventure to help you understand this better!
Examples you can see
Imagine you're on a Zoo maths quest where you have to figure out what animals are most likely to appear in different areas. Here are some examples:
| Event | Probability | Why? |
|---|---|---|
| A penguin waddles into the water | Certain | Penguins live in water and love to swim! |
| A lion eats a zebra | Likely | Lions are meat-eaters and hunt zebras in the wild. |
| A giraffe eats a leaf from a tree | Likely | Giraffes love eating leaves from tall trees. |
| A penguin climbs a tree | Impossible | Penguins don’t climb trees – they live in water and on ice! |
| A baby elephant is born | Unlikely | Elephants only give birth to one baby at a time, and it takes a long time to grow up. |
Let’s try another example:
- It’s raining – This might be likely if the weather forecast says so.
- You find a gold coin in your pocket – This is unlikely but not impossible!
- You win a prize in a game – This is likely if you're good at the game.
Try it as a mini adventure
Zoo Maths Quest: Probability Detective
You are a detective at the zoo! Your job is to figure out which animals are most likely to appear in certain areas, and which are impossible to find there.
- First stop: The bird house. What is the chance of seeing a penguin here? Impossible! Penguins live in icy places, not bird houses.
- Second stop: The big cat area. What is the chance of seeing a zebra here? Unlikely – Zebras are in the savannah area, not with lions.
- Third stop: The reptile house. What is the chance of seeing a kangaroo here? Impossible – Kangaroos live in Australia, not in a zoo reptile house.
- Fourth stop: The monkey area. What is the chance of seeing a monkey here? Certain – Monkeys live in the monkey area!
- Fifth stop: The aquarium. What is the chance of seeing a shark here? Likely – Sharks are in the aquarium!
Can you write down your own probability guesses for different zoo events? What would you say is most likely, least likely, and impossible?
Common mistakes
- Mistake: Saying that something is "certain" when it's not always true.
Why it happens: Sometimes we jump to conclusions too quickly.
Fix: Ask yourself: "Is this always true?" If not, it’s not certain. - Mistake: Thinking that "unlikely" means "impossible".
Why it happens: Children mix up the words "unlikely" and "impossible".
Fix: Remember, unlikely means "not very likely", but it can still happen. - Mistake: Using the wrong words when describing chance.
Why it happens: It’s easy to get confused between the words.
Fix: Practice using the words "certain", "impossible", "likely", and "unlikely" in sentences.
Parent and carer guide
Helping your child with probability is all about using everyday moments to talk about chance and prediction. Here’s how:
- Ask questions: "Do you think it’s likely to rain today?" or "Is it possible for a giraffe to fly?"
- Use real-life examples: When you’re at the park, talk about the chance of seeing a butterfly or a dog.
- Play games: Use dice or spinners to explore chance and see what happens.
- Encourage prediction: "What do you think will happen next in the story?" or "What do you think will happen if we flip this coin?"
- Don’t worry: It’s okay if your child gets confused at first – probability is tricky, but fun to explore!

FAQ
What does "probability" mean?
Probability means how likely something is to happen. It helps us think about chance and predict what might happen.
What are the words we use for probability?
We use words like certain, impossible, likely, and unlikely to describe how probable something is.
Can we use probability in games?
Yes! Probability helps us understand the chance of winning, rolling a number, or drawing a card in a game.
How can I help my child learn probability?
You can talk about chance in daily life, play games, and ask questions like "What do you think will happen next?"
Is probability only for maths?
No! Probability is used in science, sports, cooking, and even in everyday decisions like checking the weather forecast.
