3. Coordinate Plane - for student practice, make your own coordinate plane worksheets at the On-line Math Worksheet Generator
4. Coordinate plane - 4 Quadrants - This one-sheet workbook had a coordinate plane with nine colored dots. Use an interactive whiteboard and have your students drag the dots to represent an ordered pair that you specify.
5. Coordinate Plane Game - timed game using Flash animation, determine the ordered pair for the given point on the plane
6. Distance Between Two Points (Given Their Coordinates) - Drag the point A or B. As you drag, the length of the line segment linking them is continuously recalculated.
7. Graphing in Quadrant 1 in the Coordinate Plane - lesson plan from Teacher's Domain at WNET
8. Horizontal Line (Coordinate Geometry) - Drag the points A or B and note the line is horizontal when they both have the same y-coordinate.
9. Introduction to the Coordinate Plane and Coordinates - dialog between a mentor and student, to be used to introduce the plane
10. Line Segment: Coordinate Geometry - Adjust the line segment below by dragging an orange dot at point A or B and see how the segment AB behaves. You can also drag the origin point at (0,0).
11. Lines in Coordinate Geometry - introduction to defining the line
12. Locate the Aliens - your job is to enter the coordinates of the aliens when they appear on the plane
13. Lost My Marbles Handout - rich field text document about using a coordinate grid - [this document can be opened with MS Word]
14. Make a Coordinate Plane - You can make one quadrant, or all four, and then use the plane with an interactive whiteboard or other projection device.
15. Math Open Reference: Coordinate Plane - Drag the point A. As you drag note the two numbers that define its position on the plane. Drag the origin to reposition the axes.
16. Maze Game - This activity allows the user to practice their point plotting skills by having them move a robot through a mine field to a target location. Moves are accomplished by specifying the coordinates of the new location. In order to win, the path must not cross a mine.
17. Quiz - [all four quadrants used] enter the ordered pairs for each of the four points on the coordinate plane [This expired link is available through the Wayback Machine Internet Archive. If the page doesn't load quickly click on Impatient? at the bottom right of the page.]
18. Vertical Line (Coordinate Geometry) - Drag the points A or B and note the line is vertical when they both have the same x-coordinate.
