Graphs

This program explores the first quadrant of the Cartesian plane in the context of a city grid, then looks at using coordinates, graphing relationships and how slope is measured. Student guide available from the VEA website. www.veavideo.com (under "teacher notes").

This program provides students with a lively introduction to key concepts involved with angles, such as how we define and write information about an angle, mathematical notation for rays, line segments and lines, and how to use a protractor.
