Coordinate-plane graphing

Graph and identify points on a coordinate plane using ordered pairs in the first quadrant.

A coordinate plane is a grid with two number lines: the x-axis goes right, the y-axis goes up, meeting at the origin (0, 0). Every point has an address written as an ordered pair (x, y).

To plot a point, always move ALONG THE X-AXIS FIRST (right), then move UP for the y-value. "Over, then up" is the order that never changes.

📋 For the teacher
Teach it (10–15 min):
  • Practice the phrase "over, then up" every single time until it is automatic -- reversing the order is the most common mistake.
  • Use a large floor grid or graph paper so plotting feels physical, not just abstract dots.
  • Point out that both coordinates of the origin are 0 -- it is the starting point for every single point on the plane.
  • Have them plot several points and connect them to see a simple shape form, which makes graphing feel purposeful.
Talk about it:
  • What does the first number in an ordered pair tell you? The second?
  • Why is the origin written as (0, 0)?
  • What mistake happens if you move up before moving right?

Mastery looks like: They can plot and correctly read ordered pairs on a first-quadrant coordinate plane using the "over, then up" rule.

Common stumbles: Moving up before moving right; swapping the two coordinates when reading or writing a point.
