First go to PlaySpent.org and run through the simulation at least once. Pay attention to things like which decisions are easy and which are difficult, and which decisions are challenging to your personal morals and values.
Choose ONE of the three sociological theories (structural functionalism, conflict theory, symbolic interactionism) and use it to explain what happened to "you" and "your child" in PlaySpent. For example, you can discuss things like:
Why, according to your chosen theory, does your family have less money and fewer opportunities than other families?
According to your theory, if this were a real family would the things that happened to them be considered fair?
What beliefs and values affected your decisions during the simulation?
I am expecting a long and detailed answer that really explores the theory of your choice in detail.
