Ask Ss "Do you still see your high school friends?" "When was the last time you saw them?" Tell them discuss these questions in pairs. Nominate Ss to get w/c feedback (do not keep it long)

Remind Ss the copy of the text they used in the previous lesson. Ask them to analyze the perfect tenses and underline them Tell them to discuss in pairs what could be the difference between perfect simple and perfect continuous (as form, meaning) Write two of the sentences from the text on the w/b shark attacks have been rising, ... Human beings have explored less than ten per cent of the oceans, ... Elicit their answers about the difference between two sentences based on their discussion in pairs Direct their answers as an emphasis on duration and result by using CCQs We use the continuous form to emphasise the duration of the action (which started in the past and continues up to now) We use the simple form to emphasise the result of the action, about single completed actions or with state verbs Let them discuss and decide why the writer chose the specific tense in the rest of the sentences

Write a model sentence about yourself on the w/b, highlighting the key words to draw the students' attention to the target language. I have been teaching at universities since 2012. Does the activity continue up to and include the present?Yes Is the action still continuing? Yes When did it start ? in 2012 What do we want to emphasize ? Duration (from 2012 up to now) Draw a timeline on the w/b /let them do it or elicit from them I’ve visited my grandmother this week. Has this week finished? No Do you know the exact day when it happened? No Am I at my grandmother’s house now? Yes

Give Ss a guided discovery hand out including gap-fills for Present Perfect Simple vs. Continuous. Let them do individually first Then ask them check in pairs Tell them to write each form of the tenses in pairs. (negative, positive and question) Let them write the forms on the board. (If needed) To make the meaning more clarified give them a handout . Ask them to do the activity in pairs by discussing.

Give Ss a controlled practice First to do on their own Then checking answers with their partners Monitor them and check if they have problems with the language focus Do the error correction if necessary

Give Ss some words Tell them to write 4 sentences for each tense including affirmative, negative and question sentences in pairs. Nominate Ss to elicit their answers and write them on the board This can help to give feedback

Tell Ss to think about their own life events by using the target language Ss speak about activities they have been doing for a length of time with their partners. (ask and answer qs) Give an example if necessary Monitor them if they need help If there is time left, do the error correction as delayed FB
