Jungle maths quest: probability

Quick answer

Probability is about how likely something is to happen - from certain to impossible. In a jungle adventure, you might find a temple with a 50-50 chance of a treasure, or a bridge that's impossible to cross if it's broken.

Learning outcome

By the end of this jungle maths quest, you will understand how to describe how likely events are using words like certain, impossible, likely, unlikely, and equally likely.

• You can sort events from most likely to least likely
• You can explain why some things happen more or less often
• You can predict what might happen in a jungle adventure
• You can use words to describe your chance of finding treasure or crossing a bridge

Why this matters

Probability helps us understand the world around us. When you're planning a jungle adventure, knowing how likely it is to rain or find a temple helps you prepare. It's also useful for games, weather forecasts, and even deciding what to eat for lunch!

Learning about probability helps you think logically, make smart choices, and understand how chance works in your daily life. Whether you're trying to catch a fish, win a game, or guess which fruit is hidden in a bag, probability gives you tools to think about your chances.

How it works

Probability is all about how sure or unsure we are about something happening. Here's how to think about it:

1. Certain means it will definitely happen. Like the sun rising tomorrow.
2. Impossible means it will never happen. Like a bird flying without wings.
3. Equally likely means there's the same chance for each outcome. Like flipping a coin - it's equally likely to be heads or tails.
4. Likely means it will probably happen. Like getting a red ball from a bag with more red balls than others.
5. Unlikely means it might happen, but not very often. Like finding a golden coin in a jungle.

When you're on a jungle quest, you might see:

• It's certain that you'll get hungry
• It's impossible to find a swimming pool in the jungle
• It's equally likely to find a banana or a mango on the ground
• It's likely that you'll meet a monkey
• It's unlikely that you'll find a treasure chest

Examples you can see

Let's imagine a jungle adventure with a bridge and a vine swing. Here are some events and how likely they are:

Let's look at a real-world example:

Imagine you're in a jungle and you're looking for a monkey. There are 5 monkeys and 10 birds in the trees. What's the chance of seeing a monkey?

There are more birds than monkeys, so it's likely you'll see a bird. It's unlikely you'll see a monkey. But it's certain that you'll see at least one animal because there are animals in the trees!

Try it as a mini adventure

Let's go on a jungle maths quest! You're on a treasure hunt with your friend. You have a map with 4 paths to choose from:

1. Path A: Cross a broken bridge
2. Path B: Swing across a vine
3. Path C: Walk through a jungle maze
4. Path D: Climb a tree to get a better view

For each path, decide how likely it is you'll:

1. Find treasure
2. Get lost
3. Meet a friendly animal
4. Get stuck

Now, let's rate each path:

• Path A: Impossible to cross the broken bridge, likely to get stuck, unlikely to find treasure
• Path B: Likely to swing across safely, unlikely to get lost, likely to find treasure, unlikely to get stuck
• Path C: Unlikely to find treasure, likely to get lost, unlikely to meet an animal, likely to get stuck
• Path D: Likely to find treasure, unlikely to get lost, likely to meet an animal, unlikely to get stuck

Which path would you choose? Why?

Common mistakes

• Mistake: Thinking that "likely" means "definitely will happen".
  Why it happens: Children often confuse words like "likely" and "certain".
  Fix: Remember, "likely" means "probably will happen", but it's not guaranteed.
• Mistake: Saying that "impossible" and "unlikely" are the same.
  Why it happens: Both words suggest something won't happen, but "impossible" means never, while "unlikely" means rarely.
  Fix: Impossible = never happens. Unlikely = happens very rarely.
• Mistake: Mixing up "equally likely" and "certain".
  Why it happens: Both mean things might happen, but "equally likely" means same chance, while "certain" means it will happen.
  Fix: Equal chance = same odds. Certain = 100% chance.

Parent and carer guide

Help your child explore probability by asking questions about everyday events:

• What's the chance of getting a red ball from a bag with 5 red and 3 blue balls?
• Is it more likely to get a head or tail when flipping a coin?
• Is it possible to find a dinosaur in your garden?
• What's the chance of seeing a bird or a cat in your street?

Encourage them to think of their own examples:

• How likely is it to have a rainy day tomorrow?
• Is it certain that you'll eat lunch today?
• Can you think of something impossible?

Use the jungle adventure as a fun way to practice. Ask them to describe how likely it is to:

• Find a gold coin
• Meet a friend
• Get a good night's sleep

Remember: Probability is about thinking logically and making good guesses. It's okay if you're not sure!

Practice questions

1. Is it certain, impossible, likely, unlikely, or equally likely to find a dog in a jungle?
2. What's the chance of seeing a rainbow after rain?
3. Is it certain that you will eat food today?
4. What's more likely: seeing a bird or a snake in the jungle?
5. Is it possible to find a treasure chest in your garden?
6. What's the chance of getting a head when flipping a coin?
7. Is it likely that you will get a good grade on your maths test?
8. Is it impossible to swim in a desert?
9. What's the chance of finding a banana on the ground?
10. Is it equally likely to find a red or blue ball in a bag with 6 red and 6 blue balls?

Answers:

1. Unlikely
2. Likely
3. Certain
4. Bird (more birds than snakes)
5. Unlikely
6. Equally likely
7. Likely
8. Certain
9. Likely
10. Equally likely

FAQ

What is probability?

Probability is how likely something is to happen. We use words like certain, impossible, likely, unlikely, and equally likely to describe it.

Why do we need to know about probability?

Probability helps us make good decisions. It helps us understand our chances of winning a game, what the weather will be like, or if we'll find something we're looking for.

Can probability be wrong?

Probability is about guessing the chance of something happening. It's not always right, but it helps us think about what might happen.

How can I practice probability at home?

You can practice by thinking about everyday events and how likely they are. Ask yourself: Is it certain, impossible, likely, unlikely, or equally likely to happen?

What's the difference between likely and unlikely?

Likely means it will probably happen, while unlikely means it might happen but not very often. For example, it's likely you'll see a bird, but unlikely you'll see a dinosaur.
