Lesson Details
Key learning points
- Coordinates can be entered onto Desmos and they will be plotted.
- A rule can be entered in Desmos to generate coordinates.
- It is possible to spot coordinates that are not following the rule easily using Desmos.
- Desmos can be used to create mathematical shapes and pictures using coordinates.
Common misconception
Pupils may think that coordinates that make a square/ rectangle follow a linear pattern.
In order for coordinates to follow a rule written as an equation, there needs to be a relationship between the values within a coordinate.
Keywords
Origin - The origin is where the -axis and -axis cross. It has the coordinate pair (0,0).
