6.NS.8

About the Math

Full Standard

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.

 

Learning Targets (I can)

  • Explain the distance between 2 coordinates in the context of a problem.
  • Graph points to solve problems.

 

About the Math

  • Explain the distance between 2 coordinates in the context of a problem.
  • Graph points to solve problems.

Students find the distance between points when ordered pairs have the same x-coordinate (vertical) or same y-coordinate (horizontal).
Example 1: What is the distance between (–5, 2) and (–9, 2)? Solution: The distance would be 4 units. This would be a horizontal line since the y-coordinates are the same. In this scenario, both coordinates are in the same quadrant. The distance can be found by using a number line to find the distance between –5 and –9. Students could also recognize that –5 is 5 units from 0 (absolute value) and that –9 is 9 units from 0 (absolute value). Since both of these are in the same quadrant, the distance can be found by finding the difference between the distances 9 and 5. (| 9 | - | 5|). Coordinates could also be in two quadrants and include rational numbers. Students graph coordinates for polygons and find missing vertices based on properties of triangles and quadrilaterals.

Essential vocabulary for this standard includes: rational numbers, opposites, absolute value, quadrants, coordinate plane, ordered pairs, x-axis, y-axis, and coordinates.

Instructional Tasks

TASKS

These tasks can be used with small group or whole group instruction.

  • What quadrants will two points fall if they share the same x-coordinates? Explain your answer by providing an example. Is there another possible answer? (if they share the same positive x value, they will be in quadrants 1 & 4 and if they share the same negative x value, they will be in quadrants 2 & 3.)
  • Plot the point (5,-7) on the coordinate grid. If this point is reflected over the x-axis, what will be the resulting point?
  • If each unit on the x and y axis represents one mile and travel can only occur horizontally or vertically, how many miles does Sally travel when she moves from (4,5) to (7,11)?
  • Without actually graphing the points (2,3), (2,6) and (2,1), will the graph result in a horizontal, diagonal, or vertical line?
  • Plot 4 points on the coordinate grid that are each 5 points from the point (2,3).

 

SLIDE-BASED TASKS 

 These links are HCPSS created instructional tasks. These tasks are provided in Google slides. These tasks should be used for inspiration and resources, but instruction should start with students having the opportunity to engage with the math first (often involving physical and/or visual models) followed by discussion and explicit instruction to ensure student understanding.
