This is the first of a three-part E-Example from Principles and Standards for School Mathematics of the NCTM algebra standards and this applet is also used in an Illumination unit that highlights different aspects of students' understanding and use of patterns as they analyze relationships and make predictions. This example presents a task for students to complete using the interactive applet. Students can create pattern units of squares, predict how patterns with different numbers of squares will appear when repeated in a grid and then check their predictions. Instructions for using the applet are included and background information for the teacher is provided.
