Coordinate Plane Concepts and Quadrants

This lesson, led by Mr. Hul, covers the concept of ordered pairs and the coordinate plane. It begins with drawing and extending number lines, followed by an explanation of coordinates and the origin. The lesson then moves to graphing points on the x and y axes, emphasizing the importance of ordered pairs. Finally, it explores the four quadrants of the coordinate plane, detailing the characteristics of each quadrant and how to identify the location of points within them.
