Plotting coordinates generated from a rule

Plotting coordinates

Unit Summary

In this unit pupils revisit and further develop their understanding of the coordinate plane, and learn how to plot non-integer coordinates. Pupils then plot from an equation both by hand and by using technology.

Lesson Summary

You will learn to represent a set of coordinates, constructed according to a mathematical rule, both algebraically and graphically.

Key Notes

  • 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.

Vocabulary To Learn

  • Equation: An equation is used to show two expressions that are equal to each other.

Common Mistakes To Avoid

  • Pupils may try to spot patterns between consecutive coordinates. E.g. the y value goes up in ones.

3 Quick Questions (With Answers)

1. Solve this in steps: explain the method from this lesson and why each step matters.

Pairs of coordinates that follow a rule can be found. Pairs of coordinates that follow a rule can be plotted.

2. Use this key word in a maths sentence and explain it clearly. 'Equation'

An equation is used to show two expressions that are equal to each other. Use this word when showing your method, then check your final answer is reasonable.

3. Spot and fix this common maths mistake.

Mistake: Pupils may try to spot patterns between consecutive coordinates. E.g. the y value goes up in ones. Correction: Get pupils to think about the relationship between x and y within a coordinate. Include non-integer values and coordinates not in order.
