T starts the lesson by making links to the previous lesson. Since the positive form of the past tense has already been taught, T will build on their knowledge to add the new information.

T describes different situations through some pictures of activities she/he did last weekend and tries to elicit and introduce the related form to sts. T also uses his/her fingers to help sts figure out what they hear. Some repetitions follow to familiarize sts with the correct pronunciations before showing the form. T continues to do it until sts have their own picture of what T is trying to say.

Having familiarized sts with the target language, T puts the form on the board. A great amount of substitution drills follow to clarify the new form and show the difference between affirmative and negative forms of past tense. This part is followed by some concept check questions to make sure sts are able to distinguish the difference between the two forms.

In this stage T gives hand-outs to sts. STs will listen to a conversation in the context of "Rashin's Last Weekend" . Sts listen for specific information to say if the sentences written on hand-outs are true or false according to the listening.

T gives hand-outs of an activity called 'You did it". Instructions are given trough modelling, open pair and then in closed pairs. Sts use the prompts written on the hand-outs and take turns to guess and try to make sentences. T keeps monitoring and taking notes. The lesson ends with writing some of sts' errors on the board and ask the whole class to correct them.
