Students review horizontal and vertical lines. They find that horizontal and vertical lines are perpendicular to each other. They relate this to a coordinate plane, labeled with x- and y-axes that meet at the origin
A. Locate and label Points on a Number Line
B. Identify the origin and coordinate of a point on a number line
C. Explore coordinates on a number line
D. Use coordinates to find the distance between two points on a number line
F. Define points on a coordinate plane
G. Label coordinates on a coordinate plane
H. Plot points on a coordinate plane
I. Label points that lie on the coordinate axes
J. Use coordinates in purposeful ways
K. Explore patterns on a coordinate plane (Level 1)
L. Explore patterns on a coordinate plane (Level 2)
