The Teacher's Ultimate Sign-In Sheet- PDF Version - FREE (Back to School, Open House and many more) -- good idea! I would also use this for a field trip sign out. My last field trip everyone left since we were late coming back. Maybe I'll get them to sign out their child if they make it there before me (which they will).
Parent/ Teacher Conferences ✔️ put this out for the parents. It was so cute having the kids write about what they're proud of their learning so far (yesterday) and the parent comments added today are even sweeter!
