First mistake :don't reveal what we will teach Introduce grammar in context Second mistake:(not analysing the grammatical point )weak preparation / lack of knowledge about the grammar point you will teach (good revision of the target leg point will save you to define the suitable time alloted to the task) Awkward preparation of the lesson :( the teacher has to do the tasks itself before coming to class Third mistake: The vague and overwhelming question of elicitation The fourth mistake: Do not start the grammar point by introducing the form( you have to start by introducing the meaning) The the fifth mistake:() Modeling and drilling: Pronunciation of the structure correctly and ask students to repeat after you then the teacher write it on the board.
