Checking understanding of plotting coordinates

I can plot coordinates in the first quadrant.

Lesson details

Key learning points

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

Common misconception

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

Clarity of language helps. Coordinates are written x, then y coordinate. Move first in the x-direction. There are no 'corridors and stairs'.

Keywords

  • 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.

Slide 28 compares (2,5) and (5,2). At this moment ask students to speak. Draw out the rich, accurate language that has gone before in the lesson to explain how we consider and communicate coordinates accurately.
