North Carolina Standard Course of Study
NC.6.RP. Ratio and Proportional Relationships
Understand ratio concepts and use ratio reasoning to solve problems.
NC.6.RP.3. Use ratio reasoning with equivalent whole-number ratios to solve real-world and mathematical problems by:
NC.6.RP.3.e. Plotting the pairs of values on the coordinate plane.
NC.6.NS. The Number System
Apply and extend previous understandings of numbers to the system of rational numbers.
NC.6.NS.6. Understand rational numbers as points on the number line and as ordered pairs on a coordinate plane.
NC.6.NS.6.a. On a number line:
NC.6.NS.6.a.2. Find and position rational numbers on a horizontal or vertical number line.
NC.6.NS.6.b. On a coordinate plane:
NC.6.NS.6.b.1. Understand signs of numbers in ordered pairs as indicating locations in quadrants.
NC.6.NS.6.b.2. Recognize that when two ordered pairs differ only by signs, the locations of the points are related by reflections across one or both axes.
NC.6.NS.6.b.3. Find and position pairs of rational numbers on a coordinate plane.
NC.6.NS.8. Solve real-world and mathematical problems by graphing points in all four quadrants of the coordinate plane. Include use of coordinates and absolute value to find distances between points with the same first coordinate or the same second coordinate.
Solve real-world and mathematical problems involving area, surface area, and volume.
NC.6.G.3. Use the coordinate plane to solve real-world and mathematical problems by:
NC.6.G.3.b. Using coordinates to find the length of a side joining points with the same first coordinate or the same second coordinate.
