Five quick choices. Signed-in adults create learner profiles with a nickname and grade; this lesson setup does not ask for a school, birthday, or learner contact details.
About saving: when an adult signs in and opens a learner profile, this work is saved to that learner so lessons can be picked up later, and the adult can see it. Saving is set per learner in the family dashboard: full lesson history, results and progress only, or unsaved practice that is not added to learning history. Signed-out work is not added to an account's learning history. Family dashboard.
