Grade(s) 6 resources related to the following standard:
The Number System
Apply and extend previous understandings of numbers to the system of rational numbers.
6. Understand a rational number as a point on the number line. Extend number line diagrams and coordinate axes familiar from previous grades to represent points on the line and in the plane with negative number coordinates.
b. Understand signs of numbers in ordered pairs as indicating locations in quadrants of the coordinate plane; recognize that when two ordered pairs differ only by signs, the locations of the points are related by reflections across one or both axes.

This interactive Flash applet provides practice locating a specific point in all four quadrants of the coordinate plane. The student is given an ordered pair and clicks on the arrow keys to guide Billy to a grub hidden at that location. The player races against the clock to feed Billy ten times as quickly as possible.

This interactive Java applet allows users to plot a "house" on a -10 by 10 coordinate plane. A "view" mode allows users to enter an ordered pair and move the house to that location. The "guess" mode randomly plots the house on the plane and the user must enter the ordered pair for its location. An optional scoring feature allows users to keep track of the number correct.
