This activity is to help students see the difference between the present perfect & past simple. It´s a conversation based class for which a dice is needed or students can just pick numbers between 1-6. After the dice is rolled twice, the student must talk about the question or subject that is in the square. This process is repeated until all squares have been talked about. It´s important for the teacher to take notes and give feedback at the end. Hopefully the student will use the correct tense naturally, afterwards a grammar explanation can be given.
