Draw polygons specified by coordinates in the first quadrant

I can draw polygons specified by coordinates in the first quadrant.

Lesson details

Key learning points

  1. The first digit in the coordinate gives the horizontal distance from the origin along the x-axis.
  2. The second digit in the coordinate gives the vertical distance from the origin along the y-axis.
  3. Use a ruler to join the points you have plotted to form a polygon.

Common misconception

Pupils may mistakenly plot the y-coordinate (vertical distance) first, then the x-coordinate (horizontal distance), leading to incorrect point placement.

Reinforce that the x-coordinate comes first by using mnemonics such as "X before Y, along the ground before you fly." Practice plotting a few points together as a class to build this habit.

Keywords

  • Polygon - A polygon is a 2D shape made up of three or more straight lines.

  • Vertex / vertices - A vertex is the point where two lines meet. The plural is vertices.

  • Coordinate - Coordinates are a set of values that show an exact position.

Guide students to follow the sequence of the coordinates carefully, reminding them that the points should be connected in the order given. Encourage them to double-check their sequence before drawing lines.
