This activity/project aligns with, but is not limited to, Realidades 1 Chapter 4: Tema 1A and 1B. I have given it as a homework assignment as well as an in-class activity.
Students use relevant vocabulary from the chapter, inviting a friend to do something via a formal invitation. They also use question words.
Included is an explanation of the project, a rubric, and a key to provide students feedback on their written work. Of course, this project can be adapted to meet the needs of your students. I would say this takes 2-3 days in class, or less if you assign a part of it as homework. It could also take a week if you work on it for only a little bit each class period.
Thanks for stopping by, and make sure to check out my other Realidades 1 materials.
