Instructions

Play through this interactive game to learn about Ordered Pairs on a Coordinate Plane. Suitable for Grade 6, Grade 7, Grade 8.

Main Concepts

The y value determines the vertical movement away from the origin with positive values denoting movement up from the origin and negative x values denoting movement down from the origin.

The first number in an ordered pair is labeled the x coordinate and the second the y coordinate and is expressed as (x, y).

Location is precisely described using the intersection of those lines and line segments.

The coordinate plane is 2 perpendicular lines that serve as the starting point for describing precise location. The horizontal line is labeled the x-axis and the vertical line is labeled the y-axis.

The x value determines the horizontal movement away from the origin with positive values denoting movement to the right of the origin and negative x values denoting movement to the left of the origin.

There are 4 quadrants on a coordinate grid. Quadrant I contains all coordinates in which x and y are positive (x,y). Quadrant II contains all coordinates where x is negative and y is positive (x, -y). Quadrant III contains all coordinates where x and y are negative (-x,-y), and Quadrant IV contains all coordinates where x is positive and y is negative (x, -y).

Coordinates with same numbers but opposite signs are reflected across axis. (x, y) and (-x, y) are reflected across the y-axis. The coordinates (x, y) and (x, -y) are reflected across the x-axis. And coordinates (x,y) and (-x,-y) is reflected across both axis referred to as reflected across the origin. (diagonally reflected).

Reflected across an axis refers to being in the same position (distance from the origin) on the opposite side of the axis.

Discussion Questions

Before the Game

On the number line, which direction are the positive values? On the number line, which direction are the negative values? On the coordinate plane, what is (0, 0) referred to? What are the four quadrants and where are they located?

After the Game

How do we reflect points across an axis? Which quadrant contains the point where both the x and y values are negative? What are the coordinates of the reflection of (5, 5) across the y-axis?
