Understanding Quadrants in Coordinate Plane

In this lesson, Kaeleigh teaches how to graph ordered pairs on a coordinate grid with four quadrants. The video begins with a review of ordered pairs and the coordinate grid, then explains the characteristics of each quadrant. A review of ordered pairs in each quadrant follows, and the lesson includes a demonstration of plotting points on the grid. Finally, a reverse plotting exercise helps reinforce the concepts learned.

What is the main focus of this lesson?

• Graphing ordered pairs in one quadrant

• Learning about the x-axis only

• Graphing ordered pairs in four quadrants

• Understanding the concept of origin

What is the origin in a coordinate grid?

• The point at the top of the y-axis

• The point where the x-axis and y-axis intersect

• The point where the x-axis ends

• The point where the y-axis ends
