The blue bar at the top of the screen is your Classroom Visual Schedule, a key strategy included in your Positivity subscription used to support classroom management, student self-regulation, and executive functioning. The Classroom Visual Schedule must remain visible in order to deliver strategies within everyday routines and display future scheduled events in your classroom to help prepare students for upcoming activities.
This schedule bar can be hidden by selecting the On-Demand button (the heart icon) located in the upper right-hand corner of your screen while logged in to n2y.com and selecting the “Show class schedule” toggle. Switch the toggle to turn off the visual schedule. 
Please note that this will prevent any strategies applied to events on your schedule from displaying via the teacher login.
The Classroom Visual Schedule can be hidden in teacher view, but it cannot be hidden in student view.
