Good job man, post about your class and make it ABOUT steem, just make sure your post has something to do with Steem AND your classroom ... make a proposal on @utopian-io http://utopian.io to propose for a Budget for you to spread steem in your school, 

you create a plan where you show how many kids you could add to steem IF you had a small budget to go print flyers, pay yourself to have a job handing them out, you could allocate some money to give yourself and your friends a job,...
