Understanding Coordinate Grids and Quadrants

This lesson focuses on Module 3 Lesson 15, which covers locating ordered pairs on a coordinate plane. It introduces key vocabulary such as coordinate grids and planes, and explains the concept of quadrants. The lesson details how to label axes and quadrants using Roman numerals and describes the characteristics of each quadrant based on x and y coordinates. Special cases where one coordinate is zero are also discussed. The lesson concludes with a brief wrap-up and a preview of the next class.
