I have been playing the keyword game with my students for years and it was getting far too repetitive so I decided to mix it up a bit.
Students play in pairs, left-hand side students are one team, and the right-hand side students are the other team. After playing each round, I count how many winners from the left side, and how many from the right. I give one point to the team with most winners that round. It can continue for as many rounds as there are vocab to learn but I don't usually play it for that long.
The original keyword game goes as follows: students are in pairs with an eraser placed between them. They have their hands on their heads or behind them. When the ALT
says the keyword, the students race to grab the eraser. For the other vocab words, students repeat after the ALT and clap twice then move their hands back to their heads or behind them.
