What is 'quiz, quiz, trade', you ask? It's a very simple game that builds both language and social skills (and if you use subject-specific questions, reinforces learnt knowledge, too). You'll need to print out, cut and laminate the cards to start with. Game play is very easy so it's a useful game for all ages. I've even used this game with EAL students (English as an Additional Language) who have limited verbal English - with the right scaffolding, it works very well for them, too.
Each player gets a card. All players stand up and hold their coloured card in the air; they walk around the room looking for a player with a different coloured card than his/her own. When they find someone with a different coloured card, they give the person a high-five and partner up. One person reads the question on his/her card and the partner answers (quiz). Then the second person reads the question on his/her card and the partner answers (quiz). Finally, each person swaps cards (trade). Easy peasy, right?
As always, if you use my resources, I'd love to hear how they worked out for you in your classroom.
