Explain how negative numbers are used on a coordinate grid
I can explain how negative numbers are used on a coordinate grid.
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
Keywords
Coordinates - Coordinates are a set of values that show an exact position.
Quadrant - Any of the four areas made when a plane is divided by an x and y axis.
Axis / Axes - The x and y lines that cross at right angles to make a graph or grid.
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.
Stem sentences are an excellent way for pupils to rehearse and articulate key learning. Have them displayed in the classroom for pupils to use when needed. Introduce them using the 'I say, we say, you say' format.
