Likelihood Language
Use probability language to describe and compare the likelihood of everyday events using words such as certain, likely, even chance, unlikely, impossible
Suggested ages 9–10
Evidence of understanding
- Place five everyday events (e.g. 'the sun will rise tomorrow', 'it will snow in July', 'I'll flip heads') on a scale from impossible to certain
- Use 'likely', 'unlikely', 'certain', 'impossible', and 'even chance' correctly to describe different events
- Explain why pulling a red ball from a bag of mostly red balls is 'likely' but not 'certain'
Assessment prompt
Does Likelihood Language use words like "certain," "likely," "unlikely," and "impossible" correctly — for example, knowing that rolling a 7 on a normal die is impossible but rolling an even number is likely?
