This project allows students the opportunity to experience a cultural experience they may not be accustomed to. You may want to prolong the project a bit, allowing them to be in a "love marriage" for a week and then in an "arranged marriage" for another week. It is a risky assignment on some levels, but if you think that your students, parents, administration, etc. can handle it, it is well worth it.
You can choose any anchor text to serve as a catalyst for this project. You can you informational text to introduce the concept and generate discussion.
Once you introduce the project and read the anchor texts, the rest of the project can be done outside of class. The "marriage" can continue in class, but you are able to move forward with the curriculum.
