There are four tags that PreTeXt considers to be “project-like”. They are <activity>, <exploration>, <investigation>, <project>. We will focus on <project> here. These four tags allow a general, freeform structure similar to the unstructured <example> in Listing 15.2.1; a structure analogous to that of the structured <example> in Listing 15.2.3; and the highly-structured <introduction>, <task>, <conclusion> model shown in Listing 15.5.1.
