Checking understanding of 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 plot coordinates in the first quadrant.

Key Notes

  • Coordinates can be plotted in the first quadrant.
  • Shapes can be described using coordinates.
  • Moving all the points of a shape using the same rule will translate the shape.

Vocabulary To Learn

  • Quadrant: A quadrant is any one of the four areas into which a space is divided by the $$x$$ and $$y$$ axes.
  • Origin: The origin is where the $$x$$-axis and $$y$$-axis cross. It has the coordinate pair (0,0).
  • Plot: Drawing on a graph or map is known as plotting.
  • Translate: Translation is a transformation in which every point of a shape moves the same distance in the same direction.

Common Mistakes To Avoid

  • Confusion between which is which out of (1,4) and (4,1). Is it up and along? Along and up?

3 Quick Questions (With Answers)

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

Coordinates can be plotted in the first quadrant. Shapes can be described using coordinates.

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

A quadrant is any one of the four areas into which a space is divided by the $$x$$ and $$y$$ axes. Use this word when showing your method, then check your final answer is reasonable.

3. Spot and fix this common maths mistake.

Mistake: Confusion between which is which out of (1,4) and (4,1). Is it up and along? Along and up? Correction: Clarity of language helps. Coordinates are written x, then y coordinate. Move first in the x-direction. There are no 'corridors and stairs'.
