Interpret sets of negative and positive numbers in a range of contexts
Lesson details
Learning outcome
I can interpret sets of negative and positive numbers in a range of contexts.
Key learning points
- For negative temperatures, the further the number is from zero, the colder it is
Keywords
Temperature - How hot or cold something is.
Elevation - Used to describe an object’s height above a given height, such as sea level.
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.
Teacher tip
Take practical opportunities where possible to show pupils positive and negative numbers e.g. using fridge and freezer temperatures or local multi-storey structures.
