It consists of 2 or 3 axes X, Y and Z all at right angles to each other, and all intersecting at a specified origin. What we see around us is a three-dimensional world, because objects have three dimensions: length, width and height. A line is in one dimension, an area such as a rectangle drawn on a piece of paper is in two dimensions, and a box cube has three dimensions. In the previous definition for ordered pair, if your desk surface is thought of as a graph, you graphed the point 2,3 , meaning you represented those numbers visually or graphically.
For example, if you are told that the front left corner of your desk is the origin, and you want to find a point given the ordered pair 2, 3 and you know that the unit you are using is inches, you start at that front left corner of your desk, move two inches to the right, and then 3 inches toward the back of the desk, and you find that point. A plane is two dimensional, so it is a flat surface.
A flat table top, for example, can be thought of as a plane. Worksheet : If students are able to satisfactorily complete the 3D Coordinates Worksheet with little or no help from the teacher or peers, then they demonstrate a sound understanding of the basics of 3D graphing.

Try drawing the 3D axes on a piece of paper. Then, try to draw a cube in 3D by locating points on the axes. The points may be located in the same manner, and students will learn that the particular letters and orientation of the planes is arbitrary.

Educators Share Experiences. Summary Student groups use a "real" 3D coordinate system to plot points in space. Made from balsa wood or wooden dowels, the system has three axes at right angles and a plane the XY plane that can slide up and down the Z axis. Mark Twain. Life Death Fear Time. Your time is limited, so don't waste it living someone else's life. Don't be trapped by dogma - which is living with the results of other people's thinking.
Don't let the noise of others' opinions drown out your own inner voice.
And most important, have the courage to follow your heart and intuition. Steve Jobs. Life Courage Time Heart. Our greatest weakness lies in giving up. The most certain way to succeed is always to try just one more time. Thomas A. Motivational Time Way Succeed. Do the one thing you think you cannot do. Fail at it.
Try again. Do better the second time. The only people who never tumble are those who never mount the high wire. This is your moment. Own it. Oprah Winfrey.
