Game called Shop

Suitable for groups of up to 8 students. Each std chooses a shop. They tell the group which shop they are going to be. Then deal a complete pack of cards. Each std places a card on the table in view of everyone and simutaneously (like snap?). When a std makes a pair with someone (ie deals the same card) both stds must remember which shop the other person is and must call out an item they want to buy, e.g. a kilo of carrots or a pair of brown shoes. The items can get more elaborate in their description as the game heats up. The first std to correctly state their item from a std's shop takes the other person's cards. The winner of the game is the one with the most cards.

Warning: this can become quite rowdy so you need to keep some control and inforce rules.

You may ask students to prepare cards with pictures from magazines beforehand. Brilliant students can google & list the benefits or advantages of what they will sell.
In class, each student will join the appropriate shop before starting shopping.
Volunteers, in turn, go shopping in order to get more cards. She or he should ask a specific student to sell him or her a specific item, "I'd like a kilo of bananas, please" (or any expression learned previously to be practised).
The seller who has the right card answers, 'here you are" or any suitable expression depending on the purpose behind the game. Brilliant students may add the googled information saying for instance, "you've done good by selling bananas; they are good for this and that", getting a bonus for that extra homework.

Each volunteer has, let's say 3 opportunities to get a card from any shop.
The winner is who may get more cards and bonuses.

It's up to the teacher to ad more suitable rules and/or facilitating processes to adapt the game to one's students' abilities, previous knowledge and expectations.
