For I wish I was I did one of my favourite drinking games. After showing a PPT on the expression and doing the listening and short role play activities in the book as I am required to do, I put them in teams and each team had to say a different I wish I were sentence. If they said the same thing as another team, point went against them. Later, for I wish I had I would do categories, so mobile phones, or types of shoes, or food. Really made the kids actually have to listen to each other. Worked quite well. Students were also keeping little shortlists of what other teams were saying to help them.
