Draw polygons specified by coordinates in the first quadrant
I can draw polygons specified by coordinates in the first quadrant.
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
- The first digit in the coordinate gives the horizontal distance from the origin along the x-axis.
- The second digit in the coordinate gives the vertical distance from the origin along the y-axis.
- 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.
