Using the Coordinate Grid Application

The Coordinate Grid application has three modes: Show, Quiz and Random.  Below are the descriptions of each mode.

Show Mode

In Show Mode, clicking on a point on the grid will display a red dot at that point along with its ordered pair.  An animation is drawn to the point illustrating how the ordered pair was derived.

Quiz Mode

In Quiz Mode, the idea is to quiz on what the ordered pair is for a point that has been clicked on the coordinate grid.  To quiz, simply click on the point on the grid, enter or have the student enter the ordered pair, and click on the check button.  If the answer is correct a checkmark will be displayed along with the checkmark fireworks (if animation is on).  If the answer is incorrect the correct answer will be displayed.

Although the answer may be entered by clicking each answer box and entering the x or y coordinate, it is much easier and faster to simply type in the number.  For example, pressing the “4” key followed by the “6” key will put a “4” and a “6” in the coordinate answer boxes.  Note: Pressing “1” followed by “0” will put a “10” in the answer box.  To put a “1” and a “0” (rather than “10”) in the answer boxes type “1” then “,” then “0”.  Also, the “Enter” key may be pressed rather than clicking on the Check Button.

For fun, the Check Button may be clicked several times in a row when the answer is correct to see the particle effect check mark in action.

Random Mode

In Random Mode, a random ordered pair is displayed.  The object is to click the matching point on the coordinate grid.  If the right point is clicked a checkmark is displayed in the Random Mode box along with the checkmark fireworks.  If a wrong point is selected the Random Mode box indicates what point was actually clicked.
