Activity 1. Describing Positions of Points
YOUR TASK
Describe the position of a point on a plane using their coordinates.
Describe the meaning of mathematical words related to points.
Plot points on a plane given their coordinates.
Give examples of points that are on a line.
The video below explains how the position of a point is described in terms of their coordinates.
CHECK your comprehension
How many numbers do you need to describe the coordinates of a point on a numberline?
How many numbers do you need to describe the position of a point on a plane?
