I think it's hard for families (and YOU!) to keep track of 10 different meeting IDs. Honestly, I can't think of any good reason you actually NEED to have a big collection of them. I really recommend using the same ONE all the time and keeping it simple.
In Zoom's settings, you can personalize your meeting ID to any 10 digit number. Guess what- your school phone # is also 10 digits! So I ALWAYS just use my personal meeting room ID and if anyone needs to know what it is, it's my phone #. I know it off the top of my head and never need to look it up or hope I'm telling people to go to the right place.
You can also personalize your passcode. Something memorable or simple? That's what I do.
I put a link to my meeting room in each day's Seesaw activities, in our week-at-a-glance, and I also made a QR code for it and printed it on all our schedules and things I send home so the kids have a BUNCH of different ways to easily get to our meetings.
Btw, if they zoom in with a link (hyperlink, qr code, etc) they shouldn't need the password. Just click the link.
