This Instructional Activity is a part of the Lesson 14, Unit 3, Grade 6. Instruct students to rotate their desks degrees in one direction. This changes the orientation of the rows so that students can better see the meanings of each of the coordinates. Students understand that the coordinates of their location from the Opening Exercise (in most cases) are different in Example 1. For example, the student sitting in row 1, seat 3, for the Opening Exercise, is now sitting in row 3, seat 1.
