The lesson plan aims to teach pupils about interrogative pronouns. It includes objectives, subject matter, procedures and evaluation sections. The procedures involve a dialogue reading activity where pupils take turns reading parts of a conversation between a mother and son. This is followed by a presentation and examples of the seven interrogative pronouns - what, why, where, who, when, which and how. Pupils then practice forming questions using the interrogative pronouns and identifying them in sentences. The lesson concludes with an exercise evaluating the pupils' understanding of interrogative pronouns.
