The calling-line ID (CLID) should be sent to your home phone unless it is blocked. Call your cell-phone provider and ask to have your CLID unblocked.
If the CLID is blocked, there is no way to do anything like you suggest. The only alternative is to come up with a "code". Call your home and let it ring once or twice. Hang up. Call right back. Teach the kids this. Alternatively, you could hook up an answering machine and when it answers, talk and your kids will hear you. You could say "Pick up the phone".
Just some ideas.
