All my lesson were divided into three stages: PRESENTATION STAGE: As we know presentation stage occurs when learners watch what the teacher does and listen to his or her explanations. First if all, I stablish the objectives of the lesson planning ,chose the contexts and activities that increased students motivation. So, I considered the following items: The language item to present: Funtion: introducing members of family. Structure: possesive 's. Phonological: pronunciation of s sound. Lexical: vocabulary related to members of a family.
