Lesson Details
Key learning points
- Coordinates can include negative values
- The x or horizontal value is always the first value in a coordinate
- The y or vertical value is always the second value in a coordinate
Common misconception
Pupils can get mixed up with which comes first, the x or y axis, when reading/plotting coordinates.
There are lots of aide-mémoires to remember the order. However, regular practice using a stem sentence like the one in the lesson will help.
Keywords
