Divide the class into two equal teams. Everyone in the class should have several pieces of paper and a pen. Have one player come up from each team and sit at the front of the class. The teacher reads a sentence, e.g. "It was so hot yesterday my ____blank____ melted.“ The teacher uses the word 'blank' as the missing word in the sentence. The aim of the game is for each team member to write down the same "blank" word as their player at the front of the class. Both players and team members keep their answer's secret. When everyone has written a word, you ask the players to reveal their answers. For each answer, the team members have that matches their player's answer. They get a point. Repeat with different players.
