What This Standard Means
What Students Need to Do
- Students follow a clear sequence to locate a point on a first-quadrant grid. They begin at the origin, move horizontally using the first number, then vertically using the second number.
What Mastery Looks Like
- Students start at the origin, use the first coordinate for horizontal movement, and use the second for vertical movement. They plot the point accurately and explain each move using axis names or directions.
Common Misconceptions
- Students may move up before moving right, switch the x- and y-coordinates, or count from the wrong point. They may also place points on grid lines without checking the scale.
How to Assess It
- Give students the point (4, 2). Ask them to plot it, then write two steps explaining how they located it from the origin.

Ways to Teach It
Make a floor coordinate grid with tape, then have students walk from the origin to ordered pairs called by a partner.
Ask students to explain why plotting (2, 5) gives a different location from plotting (5, 2).
Play Coordinate Bingo by calling ordered pairs for students to plot and cover on first-quadrant game boards.
Use a simple park map grid and have students write directions from the origin to each labeled location.
