I use this handout to reinforce understanding of the cultural concepts found throughout the chapter. The questions provided cover all of the Fondo Cultural sections as well as many of the other activities that relate to culture. (Included in this set of questions are fondo cultural, gramática, connexiones, el español en el mundo del trabajo, exploración del lenguaje, and adelante.)
If used as an individual assignment I suggest you allow for up to 60 minutes for students to complete the activities since in the second realidades book the readings are almost exclusively in the target language.
If working in groups I suggest you differentiate the readings using a jigsaw method and have each group master one section of the work before moving on to share their understanding with others.
