From the Playground mobile app Home screen, tap the "View Ratios" button to the right of the number of students checked in or absent. Each active classroom will be listed with the number students and staff currently checked into the classroom. Below that count there will also be the "Last name to face" done in the classroom. To the right of each classroom, you will see if the classroom is "In ratio" and what that ratio is, "Out of ratio" and what the ratio is, or "No ratio set" if no ratio has been set in the Admin Dashboard.
