Example 1

This Instructional Activity is a part of the Lesson 14, Unit 1, Grade 6. Elicit prior knowledge of the coordinate plane from Grade 5, where students plotted points using ordered pairs of numbers identified as coordinates, identified x- and y-axes, and determined how to travel along the axes based upon the ordered pairs. Display the completed table and coordinate plane. Should materials be available, students can use sticky dots to aid in plotting points on large gridded chart paper. Have students determine the following through questioning and discussion: We use the horizontal and vertical axes to measure quantities.
