Teaching the present perfect tense

Am teaching the present perfect tense tomorrow-yeah I know you're sighing too :) The most difficult tenses to teach in my opinion, are the present perfect and the past perfect. This is how I normally teach it:

• I always teach it together with the simple past tense because the two contrast really well.
• I use time lines to show the past and the present divisions on the board.
• I maximise the use of the board (don't let the worksheets do the talking for you)

          E.g. I read the newspaper yesterday.

• start with a sample sentence in the simple past and explain (explaining from a rule written on a worksheet is not effective, teacher explains why it's the simple past with the aid of the timeline)
• then I write a sample sentence in the present perfect tense:

          E.g.  I have read the newspaper yesterday. (explain why this is wrong by writing the following on board:

• the present perfect talks about how long and how many times- we don't need a specific time
• the simple present talks about when
• use questions too:  How many books have you read?/ How much money have you got? to reinforce the concept. Let ss answer in the present perfect.

•  this is followed by practice sentences (yes, worksheets at the end for practice)

There are many videos on how to teach the tense in Youtube and TeacherTube. I hope my lesson will go well tomorrow. It all depends on whether my fever subsides. If you have any suggestions at all, please leave a comment. Tx. have a perfect Sunday :)
