Problem solving with plotting 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 use your knowledge of plotting coordinates to solve problems.

Key Notes

  • 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.

Vocabulary To Learn

  • Plot: Drawing on a graph or map is known as plotting.

Common Mistakes To Avoid

  • Adding the length of the side onto the wrong value within a coordinate.

3 Quick Questions (With Answers)

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

You can describe the relationship between coordinate pairs in words. It is possible to identify points which do or do not follow a rule.

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

Drawing on a graph or map is known as plotting. Use this word when showing your method, then check your final answer is reasonable.

3. Spot and fix this common maths mistake.

Mistake: Adding the length of the side onto the wrong value within a coordinate. Correction: Use sketches/ erasable axis/ Desmos to plot points and see if they are reasonable. Encourage writing/drawing on diagrams as working out.
