Hedonistic Traveler:
I am the laziest fucking planner on this planet, I plan NOTHING.
If these things work with midde-aged, staunch Thai yellow shirts then they'll work easily with kids. It helps to have 101% energy (which I do when I teach)
1) The serious recommendation:
http://www.breakingnewsenglish.com/ : Print of the 'two-page mini lessons'. Easily eat up an hour. Do this with your class of Middle schoolers who sleep at the table and have already had ten hours of education before their lesson with big-nose.
2) Ask everyone five questions. Get everyone to stand up, walk around the room and ask each other 5 questions. It can be as easy as 'What's your name? What's your job?' or more difficult (This has eaten up 30 minutes before. You can then ask everyone "What did you find out about Kim-Jong-Lee? and it'll eat up another 30 damn minutes. Demo it on yourself first to get the juices flowing. Usually my students ask me "How many girlfriends do you have?" and we all laugh and pat our knees and occasionally someone throws up with all the excitement.
3) The gossip game. You tell one person in the class to keep their mouth shut. Then everyone else shouts out things they know/think they know about that person. Easily kills 30 minutes with my students. After you ask the person if its true. I play this game nearly every class, they fucking love it.
4) Compliments. Tell everyone to walk around and give each other two compliments "you're hair looks lovely!", "I love your bag". They find this hilarious for some reason. Maybe add some crap in about replying to compliments if you can be bothered.
5) Find someone who....... This takes 2 minutes to prepare. Print of a table on some paper with things like "has a girlfriend", "cannot swim", "hates cats, "thinks their civil liberties are being forever curtailed in the name of counter-terrorism". They walk around and ask questions. It eats up 30 minutes. Then feedback eats up another 30.
6) Debates. Start of the class with 'What do you usually debate about?' to extract the language/emotion from THEM. Never GIVE them the crap, get it out from them and throw it back. Then when you've got them to write down things such as "I think kimchi should be eaten on the hour, every hour rather than just three meals a day" you ask the groups to discuss
7) Selling shit. I got my Thai students to try and sell things they would never buy in a million years, such as 'Indian food', 'Tanning lotion' and 'Independent thought'. They had to prepare presentations. and convince people to buy their product.
8) Drama. Role-plays. Group one, you're at an airport. Group two, you're a couple arguing. Group three you're giving birth. You have twenty minutes. After you'll show everyone
9) A love story. I get them to answer ten questions. e.g 'Where is a good place for a date?', 'Name a nationality', 'Describe a beautiful woman' Where is a good place to meet someone?". Ok, now write a story about Teacher Leighton, I'm on a date with a gir. After you're gonna read it out to us
10) Make a movie. I elicit ten words. e.g. "What is a smelly fruit?" "What is something you tell a girlfriend?" "Name a place?" then I give them a line like "Wait a minute, that's my hat". They have to make a play, then show it to the class after
11) ASK ME ANYTHING These can get good questions. Get them to write questions for you first. I've had "How many girlfriends have you had?" "Have you ever been to a ladyboy pub?" "What do you think of the Thai prime minister". You then answer. Then say "Ok, now you can ask each other, stand up and ask everyone"
Do some of these and you're kids will laugh, it'll look like you're doing a good job, you'll never have to plan and you'l be able to teach when hung over as piss
