Canteen managing, starting up in school.

I am planning officer designated, at the same time I am a Technology Livelihood Education teacher. I want to teach my grade 9 and 10 student to work or to make, cook and sell goods to others. But no idea at all how to start. I want to an efficient and effective teacher at the same to teach students in a canteen experiencing actual and real performance. please do something for it. Thanks

Alena, welcome to permies!  I don't know what Technology Livelihood Education is.  My daughter had several fund raising projects when she was in school.  You could sell baked goods at recess or at lunch break if your school will allow this.  My daughter had a successful business selling fancy suckers to her friends until the school put a stop to it since the money her friends paid her no longer went to the vending machines.

Learning how to organize events, securing products and then selling them is a great learning experience for the kids.  I wish you the best in your teaching efforts.

I think bicycle repair would be something useful to most of your students. You might be able to have one of the parents come and assist if they have the skills.

There are many sheet metal roofs in the Philippines. They get incredibly hot. Solar hot water heating systems can be placed on them. Again, you would probably want to bring in a local expert to demonstrate this to the kids.

Solar ovens can be made very cheaply, from recycled materials. This is something that kids could learn to make and sell.

There are small cook stoves called rocket stoves, that can be made from the type of cans that fruit, vegetables and coffee sometimes come in.

Are you in an all-boys or all-girls school or is it a mixture?
Edit - I just realized that a canteen may be a kitchen. Are you teaching cooking skills?
