This site is not deigned to be a standalone teaching tool. It may be difficult for instructors to write lessons based on the information contained on the site. Prerequisite knowledge for the different pieces is assumed, but not explicitly stated. Learning objectives are also not present because the site is not designed to include this type of information.
In terms of the Monopoly Game, information provided is primarily focused for instructors, who then would design the game for their courses. No rubrics are provided to inform students as to how the assignments (included) are being evaluated. Collaboration on assignments (if more than one student playing the same piece in the same game) is not permitted. This approach would be very hard to enforce.
