Lesson Plan

Describe the coordinate plane as two perpendicular number lines (axes) that intersect at the origin (0, 0).

Identify and label the x-axis, y-axis, and origin on a coordinate plane.

Explain the meaning of each number in an ordered pair: the x-coordinate tells how far to move horizontally from the origin, and the y-coordinate tells how far to move vertically.

Plot points in the first quadrant given ordered pairs with whole-number and simple decimal or fraction coordinates.

Write the ordered pair for a point already plotted on a coordinate plane by reading its horizontal and vertical positions.

Demonstrate that order matters in an ordered pair by showing that (3, 5) and (5, 3) represent different points.

5.G.A.1

"Use a pair of perpendicular number lines, called axes, to define a coordinate system, with the intersection of the lines (the origin) arranged to coincide with the 0 on each line and a given point in the plane located by using an ordered pair of numbers, called its coordinates. Understand that the first number indicates how far to travel from the origin in the direction of one axis, and the second number indicates how far to travel in the direction of the second axis, with the convention that the names of the two axes and the coordinates correspond (e.g., x-axis and x-coordinate, y-axis and y-coordinate)."
