A good game if you fancy watching a shouting match to practice some lexical sets. Each team has a pink post it note or any other scrap of paper to hand and on the top is written a category. For example 5 things you wear / 5 things you find in the kitchen / 5 things you listen to etc. Each team quietly, secretly form a list of the 5 things for the category on their paper.
Afterwards, in turn, they announce their lexical set title to the other teams and those other teams have 30 seconds to guess what is written on their paper. For every word not guessed/shouted the team gets a point. (if you want)
