Ok, here’s a New Jersey kid (2nd grade) who places hyphens between the numbers of dates.....

I have to initial and date documents all the time. Every day. If you looked at them you'd see some dates with slashes and some with hyphens. I don't know why, maybe I get bored doing it the same way all the time. But I do know that there is no universal choice that people use in the US. The hyphen vs. slash question tells us nothing.

Here is a sample of a New Jersey 3rd Grade teacher using all upper case letters for titles, with larger upper case for the start of each word.
