Description

You are the newest robot operator at Sammie's Salvage Co.! Use ordered pairs to direct your robotic companion, BoXY, to dig up valuable artifacts. Use the money you earn to purchase exciting upgrades! Learn about the coordinate plane, the four quadrants, and reflections across axes, and put this knowledge to the test by unearthing buried treasures!

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

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).

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).

Discussion Questions

Before the Game

What are the two parts of a coordinate plane? How is the coordinate plane like a number line? How is the coordinate plane different from a number line?

After the Game

What are the coordinates of the origin on a coordinate plane? How are the four quadrants identified on a coordinate plane? In which directions do the x and y coordinates of an ordered pair have us move? In which Quadrant will both the x and y coordinates be negative? What is a reflection? What happens to the signs of the coordinates during a reflection across the x and y axis?
