Plotting coordinates generated from a rule
I can represent a set of coordinates, constructed according to a mathematical rule, both algebraically and graphically.
Plotting coordinates generated from a rule
I can represent a set of coordinates, constructed according to a mathematical rule, both algebraically and graphically.
Lesson details
Key learning points
- Pairs of coordinates that follow a rule can be found.
- Pairs of coordinates that follow a rule can be plotted.
- Coordinates that follow a rule will follow a pattern.
- A rule can be identified from the pairs of coordinates.
Common misconception
Pupils may try to spot patterns between consecutive coordinates. E.g. the y value goes up in ones.
Get pupils to think about the relationship between x and y within a coordinate. Include non-integer values and coordinates not in order.
Keywords
Equation - An equation is used to show two expressions that are equal to each other.
