Key learning points
- You can describe the relationship between coordinate pairs in words.
- It is possible to identify points which do or do not follow a rule.
- A line represents an infinity of points that follow a rule.
- You can describe the relationship between coordinate pairs using algebra.
Common misconception
Adding the length of the side onto the wrong value within a coordinate.
Use sketches/ erasable axis/ Desmos to plot points and see if they are reasonable. Encourage writing/drawing on diagrams as working out.
Keywords
