Question

Now, let's do some role play.
You should rold play with the dialogue I gave before. Do you have the handout? Take it out and practice the role play in pairs.
I will call your number. If I call a number, the person of the number should come up with his partner and looking at the picture and the menu, they should role play. Got it?

(Would you check the passage, please? Thank you.)

Answer 1

Only two things:

check spelling of "role"

and

Instead of this -- "I will call your number. If I call a number, the person of the number should come..."

Write this -- When I call out a number, the person of the number should come

Answer 2

... the person with the number ...

(Not "of")
