In this lesson we will answer the question:

How are ordered pairs of numbers represented on a coordinate grid?

You will need a copy of the print out called M5L#43 coordinates-1 to use for this lesson.

So pause the tape, print the handout, and then restart the tape.

Vocabulary

coordinate plane- is a flat surface formed by two intersecting, perpendicular lines. Each of these lines is called an axis.

x-axis- The horizontal line.

y-axis- The vertical line.

slide7

Vocabulary

Quadrants-The x-axis and the y-axis divide the coordinate plane into four areas. These areas are calledquadrants.

Ordered Pairs- Digits that indicate where a point is located on a coordinate grid. Ex: (3,2)

slide8

Connecting to Previous Learning

A coordinate grid makes it easy to locate a point on a map. Start at 0.

The ORDERED PAIR names a point on a coordinate grid. You may have used this skill while trying to locate a place on a map.

The numbers are all positive.

How would we locate the ordered pair, (3,2)

Lesson Review

  • A coordinate grid makes it easy to locate a point on a map.
  • Start at 0. You follow the 0 line to locate the 1st number, the x-coordinate in the ordered pair.
      • (3, 6)
  • The second number, the y-coordinate names the distance UP from the x-coordinate.
      • (3, 6)
