Unit 8: Graphing rational numbers
Unit Description:
This unit extends student understanding of number lines into the four quadrants of the coordinate plane. Students will draw polygons in the coordinate plane by connecting points and calculate side lengths by analyzing the distance between those points. Students will graph when linking ratio tables and points in Quadrant I of the coordinate plane.

IN THIS UNIT, STUDENTS WILL:
● 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. ● 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. ● Find and position integers and other rational numbers on a horizontal or vertical number line diagram. ● Find and position pairs of integers and other rational numbers on a coordinate plane. ● Solve real-world and mathematical problems by graphing points in all four quadrants of the coordinate plane. ● Use coordinates and absolute value to find distances between points with the same x-coordinate or the same y-coordinate. ● Draw polygons in the coordinate plane given coordinates for the vertices ● Use coordinates to find the length of a side joining points with the same x-coordinate or the same y-coordinate. |
