The daily lesson plan aims to teach 25 secondary school students aged 13 about the use of the auxiliary verbs "do" and "does" in negative and interrogative sentences. The teacher will introduce the topic through a personal anecdote and explain how "do" is used for first and second person sentences while "does" is used for third person sentences. Students will practice forming sentences with "do" and "does" and be evaluated through exercises identifying correct and incorrect usage of the auxiliary verbs. The goal is for students to master the use of "do" and "does" in different contexts.
