Divide students into groups. Tell the class that each group has £20,000 to spend. Try to buy as many correct sentences on the worksheet as possible. The group that has the most correct sentences wins.
(You can also use tactics to persuade other teams to buy the incorrect ones, for example, bidding for incorrect sentences.)
Give each group one copy of the worksheet. You can draw a table on the whiteboard and keep track of the money each group bids and how much they have left.
