You can invite families to view the student's journals by clicking the Families button in the right hand corner. You will be redirected to a page that will give you three options for granting parents access to their child's Seesaw journal. The first is mobile number (if known), the second is email address, and the third is printing QR codes to physically hand parents. Once they have accepted the invite, their Invite Status will change, so you'll be able to see when a parent has connected.
You can toggle on or off family sharing or family likes, and that can be found in the Families section of the Class Settings. Once logged in, parents will be able to see solely their child's work, so they can always stay updated on what classwork looks like. If you would like more information on what parent's see or how to help them log in if they have issues or questions, you can visit Seesaw's Help Center page on the subject: https://help.seesaw.me/hc/en-us/articles/203012019-How-do-I-invite-parents-and-families-
