Plotting non-integer coordinates

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 describe and plot coordinates, including non-integer values, in all four quadrants.

Key Notes

  • Coordinates with any values can be plotted.
  • Coordinates can be described in all four quadrants.
  • Shapes can be described using coordinates.

Vocabulary To Learn

  • Integer: An integer is any positive or negative whole number or zero.

Common Mistakes To Avoid

  • That coordinates only exist, and can only be plotted, on the lines of graph paper.

3 Quick Questions (With Answers)

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

Coordinates with any values can be plotted. Coordinates can be described in all four quadrants.

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

An integer is any positive or negative whole number or zero. Use this word when showing your method, then check your final answer is reasonable.

3. Spot and fix this common maths mistake.

Mistake: That coordinates only exist, and can only be plotted, on the lines of graph paper. Correction: Between any two vertices there are infinitely more points. Ask pupils to consider what numbers are between 1 and 2.
