My class for next year is in the database. I have all their names, addresses, numbers, parent info - and even academic and attendance data from last year that I can access from home. They will not get any information from the school indicating that I am their child's teacher until late August when the secretaries come back from vacation. So in the meantime, I'd like to either call or write them and give them my class supply list (there's very little on it, so I bascially don't want them going out and buying tons of stuff they don't need). I don't have parents emails though, however, I have found some of them on Facebook. Is it too early or should I wait until closer to the start of school?
