Discovering Chance & Uncertainty!
Learning Intention
I can describe the chance of an event happening.
What Is Chance?
Chance tells us how possible it is for something to happen. Sometimes things are certain, and sometimes they're a surprise!
What Is Uncertainty?
Uncertainty means we are not sure if something will happen or not. We often have to guess!
Our Four Chance Words:
likely - it probably will happen
unlikely - it probably wont happen
certain - it will defiantly happen
impossible - it cannot happen
Chance in the Weather
Is it certain it will rain tomorrow?
No! The weather is often uncertain.
Flipping a Coin
When you flip a coin, it could land on heads or tails.
Each is just as likely.
Real-Life Example: Snack Time
Is it likely, unlikely, certain or impossible that Primary 2 will get out to play at break today?
You might get a piece of fruit or a sweetie for snack. Which do you think is more likely today?
Uncertainty in Games
Will Primary 2 play Olly the Octopus in PE?
likely
unlikely
certain
uncertain - impossible to know
It's uncertain! We have to wait and see.
Mini Task: Likely or Unlikely?
Look around! Is it likely or unlikely you will see a cat on your walk home today?
Share your ideas.
