Key learning points
- For negative temperatures, the further the number is from zero, the colder it is
Common misconception
Negative temperatures relate to positive e.g. −5℃ is warmer than −3℃ because 5℃ is warmer than 3℃.
Emphasise directional relationship e.g. numbers decrease as they move to the right. Practical examples can help e.g. freezer temperature.
