The document provides details about an English language lesson given to secondary school students in Rio Colorado, Argentina. The 80-minute lesson focused on places in cities and used the structures "there is/there are" in sentences describing an ideal city and a real city. Students practiced reading, writing, and listening skills through activities revising vocabulary, correcting sentences, and producing their own descriptions of favorite cities. The lesson aimed to develop students' reading, writing, listening and language skills related to describing locations and existence using the new grammatical structures.
