New grade-specific activities, classroom tips, and sub-day resources. No spam, unsubscribe anytime.
Substitute teachers walk into classrooms every day with no access to district platforms, poorly written plans, and no way to report back. Students lose a day. Teachers come back blind.
Subs can't log into Google Classroom, Canvas, or the district SIS. They're locked out of the tools every other teacher uses.
Many teachers leave vague instructions or nothing at all. The sub improvises. Students disengage. Learning stops.
Teachers return with no idea what happened. Did students work? Were there issues? Sticky notes on the desk don't cut it.
Three steps. No district login. No training required.
Walk into any classroom. Open SubDesk on your phone or laptop. Select the grade and subject you're covering today. That's it.
SubDesk serves age-appropriate, standards-aligned activities that students can work through independently. Display on the board or share a class link. Students stay engaged while you manage the room.
At the end of the day, SubDesk compiles a structured report: which activities were used, how far students got, your notes on behavior or issues. Sent directly to the absent teacher's email. They come back informed.
Built to meet K-12 privacy standards from day one. Not as an afterthought.
SubDesk exists because substitute teachers deserve real tools, students deserve real instruction, and teachers deserve to know what happened while they were gone.
