Students will be able to identify collinear points. Discuss with students the definition of a point and a line. A point is one of the basic undefined terms in geometry. Points have no dimension, are represented by dots when plotting, and are named by capital letters. A line is another basic undefined term of geometry.
Lines extend indefinitely and have no thickness or width.
Lines are represented by double arrows and named by lower case letters. A line can also be named using double arrows over capital letters representing two points on the line. Next, have students practice identifying the difference in points and lines. Students should understand that points that are on the same line are collinear points. Once the students understand the difference in points and lines, have students use a GPS device to plot the coordinates of a specific location.
