5.8.A
The Standard
describe the key attributes of the coordinate plane, including perpendicular number lines (axes) where the intersection (origin) of the two lines coincides with zero on each number line and the given point (0, 0); the x-coordinate, the first number in an ordered pair, indicates movement parallel to the x-axis starting at the origin; and the y-coordinate, the second number, indicates movement parallel to the y-axis starting at the origin

What This Standard Means
What Students Need to Do
- Students identify the x-axis, y-axis, and origin on a coordinate plane. They read ordered pairs and explain how each number determines the horizontal and vertical movement from the origin.
What Mastery Looks Like
- A student correctly labels the x-axis, y-axis, and origin. Given an ordered pair, the student moves horizontally for the first number, then vertically for the second number, and explains the path.
Common Misconceptions
- Students may reverse the coordinates or move vertically for the first number. Some label the origin as (1, 1) or count it as the first step. Others move diagonally instead of making two separate moves.
How to Assess It
- Show an unlabeled coordinate plane with point P at (4, 2). Ask students to label both axes and the origin, name P, and explain how to reach it.

Ways to Teach It
Make floor axes with painter's tape, label the origin, then have students walk to ordered pairs while narrating each move.
Ask students to write why (2, 5) and (5, 2) name different locations, using x-axis, y-axis, and origin.
Play Coordinate Bingo by calling ordered pairs while students cover matching points on preprinted coordinate grids.
Give students a gridded zoo map and ask them to name the ordered pair for each animal enclosure.
