Students are given a worksheet with different answers from each unit studied (I did units 1, 2, and 3 so I had country flags, feelings and fruit). Students choose from the options their answer and write a number beside the fruit on their worksheet. Students are then given a worksheet with a bingo sheet on it, with each cell having a fruit. 

Students make pairs and exchange the conversation. I did mine as follows (students A and B):

A: Hello! I’m from [country]

B: Hello! I’m from [country]

A: How are you ‘B’?

B: I’m [feeling]! How are you ‘A’?

A: I’m [feeling]! How many [fruit]?

B: [number] + [fruit]! How many [fruit]?

A: [number] + [fruit]

They then fill in their friends number for the fruit they asked for in their bingo sheet. If you want to play a second round, have the students write the fruit in the blank bingo sheet where they want them
