A Secret Code: Patterns focuses on different ways to represent patterns, including physical models, tables, graphs, and symbols. Students describe patterns as well as extend them. In all but one instance, the patterns are linear.

The program begins with a look at alphabetical codes. Simple alphabetical codes can be designed by using a pattern. By the same idea, codes can be broken by identifying patterns.

In addition to alphabetical codes, the X-team encounters patterns using physical models of square numbers. As they describe the pattern in multiple ways, noticing an odd-even-odd-even repetition, they uncover square numbers.

They then move on to tabular formats of linear patterns. The data tables can be graphed and the characteristics of the graphs used to identify later patterns. For example, students notice that the intersection of the graph of the line for the pattern on the y-axis identifies the constant that is added in a numerical pattern. Then, by working backwards, the X-team can find the coefficient needed to complete the rule for the pattern. Finally, they write the pattern as an algebraic expression.

The information given to students is now reversed. Instead of data in a table, they are given a graph. From their previous experiences, they realize that data can be taken from a graph and put into a table.
