MATH: The Coordinate Plane

Posted on January 24, 2012. Filed under: Math | Tags: The Coordinate Plane |

Key terms from today’s lesson:

• Coordinate Plane
• x-axis
• y-axis
• Origin
• Quadrant
• Ordered Pair

Some of what we did today with the Coordinate Plane may have been a review, and some of it may be new.

Here are some tricks to help you:

• Find the first quadrant and make a big “C” and that will help you remember which quadrant is II, III, and IV.
• The x-axis is the horizontal one – remember it’s like when you sign your name at the X________.
• The x-axis and the y-axis work just like number lines do when you work with integers.
• X comes before Y in the alphabet and X always comes before Y in an ordered pair.
• The “origin” is (0,0) – think O for Origin = 0 for zero – O=0

Here’s a Kahn Academy video with more of a review for you:

Finally, here is a link to a website where you can practice working with coordinate planes on the computer.
