I made this worksheet for my Thai elementary students. They are always confused about have got/ has got and how to use them in a sentence. It is pure grammar and I explained affirmative, negative, question and contraction forms of have got and each section is followed with some examples and exercises. I used some of Good Grammar Book examples. At the end of the lesson I ask them to describe their appearances, families and objects they have in their bags. I hope it helps your students too. Happy teaching :)
