Apple device management for families

Is there a resource, on this Web site or elsewhere, that provides guidance for families in the ongoing issues around device management? My current problem is I want my kids to have phones with them when they're not in my care, but to share the same phone number across their personal devices. I've got us all using Apple products in order to makes things easier, but on this issue I'm in the dark.
