Locating Points Using Cartesian Coordinates

Put on your thinking caps because middle school math has never been more interesting in this huge resource full of thought provoking questions. Written as a newsletter, the resource has 10 two-page newsletters with a variety of...

Sal's goal in this video is to "familiarize ourselves with the x, y-coordinate plane." If your pupils have blank expressions when you present them with graphing problems, this video will be a great help to clear up the basics.

Sal defines polar coordinates and the relationships between Cartesian coordinates and polar coordinates using basic trigonometric identities and the Pythagorean Theorem in this introductory video.

Examine the features of the coordinate system with a video that describes the basics from quadrants to axes. The instructor then demonstrates how to locate a point given by an ordered pair. 

You can't get from point A to point B if you can't find point A. Using a helpful video lesson, viewers learn how to plot points on a coordinate plane. The instructor emphasizes the vertical and horizontal distance of the x and...

What's my line, anyway? A video covers the aspects of finding an equation of the best-fit line for a set of data. It works through plotting the points to drawing a line that appears to represent the data. The presenter suggests finding...

Discover the parallel structure of parallel lines. Provided with two parallel lines on a coordinate plane, the presenter shows that the rise and run, or slope, of the two lines are the same. The resource, which is a portion of a larger...

So you have an ordered pair and you want to graph it. Just remember that the first value is plotted along the x-axis and the second value in the pair is plotted along the y-axis. So count left or right, then up or down and you have...

Here is an activity that merges technology with life skills as individuals use Google Earth to explore the differences between coordinate systems and map projections. The self-guided worksheet is the fourth segment in a nine-part unit....
