Grade 5 · Math · Flashcards

Practice the key vocabulary terms used to describe and navigate the coordinate plane.

Flashcards

Coordinate Plane: A flat surface formed by two number lines — one horizontal (x-axis) and one vertical (y-axis) — that intersect at right angles.
x-axis: The horizontal number line on a coordinate plane, running left and right.
y-axis: The vertical number line on a coordinate plane, running up and down.
Origin: The point (0, 0) where the x-axis and y-axis cross each other.
Ordered Pair: A pair of numbers (x, y) that gives the location of a point on the coordinate plane.
x-coordinate: The first number in an ordered pair; tells how far to move left or right from the origin.
y-coordinate: The second number in an ordered pair; tells how far to move up or down from the origin.
Quadrant: One of the four sections of the coordinate plane, labeled I, II, III, and IV.
Quadrant I: The upper-right section of the coordinate plane, where both x and y are positive.
Plot a Point: To mark the location of an ordered pair on the coordinate plane.
Grid: The network of evenly spaced horizontal and vertical lines that make up the coordinate plane.
Coordinate: A number that indicates the position of a point along an axis.
