Your library is yours to reuse. Students only see what you share or attach.
Upload a file or paste a link, then give it a title, subject and kind: “Worksheet”, “Link”, “Vocab deck” or “Slides”. Tags and a folder-style collection let you search, sort and group your library later.
When there are ready-made units for a subject you teach, a card for them sits at the top of Resources. “Preview the unit” shows the whole thing first, and importing copies it into your library to edit. Chess coaches can pick “Chess (PGN)” as the kind and paste in a game.
“Share” makes a resource available in their portal for every lesson, and the row then reads “Remove”, which takes back every share of it. A collection has “Share all” at its heading, so an imported unit goes across whole.
Until a student accepts their portal invite, what you share waits for them, and a banner says so.
It's right on the lesson screen. A resource already on this lesson reads “Attached ✓”; one your student already has shows “already shared”. Your student finds it on that lesson's page under “Shared for this lesson”, and on their “Resources” shelf.
Files they upload from their portal collect at the foot of the lesson's materials card, under “From” and their first name, and on the student's Resources tab with an “Open lesson” link.
