Close the gaps before
your next lesson.
Co-Teacher makes it easier for teachers to analyze their students' written work and respond through a quick, research-backed routine each day.
Three easy steps.
Snap photos of student work
During or after class. Paper-based, any subject, any curriculum, any language, any grade level. Co-Teacher reads handwriting with no special scanning required.
We analyze and prep materials
Within the hour, you receive a Lesson Brief (who got what, what to target), Co-Slides featuring your students' work side by side, and personalized worksheets: one set for students who need reteaching, one for students ready to go further.
Run it the very next class
Co-Slides handle pacing, timers, cold calls, and music so you can focus on what only a teacher can do: observing responses, guiding discussion, and supporting student growth.
How this helps students
Respond to every student’s work.
Analyze written responses, reducing students’ screen time. No work goes unassessed.
Gaps close before they compound.
Misconceptions addressed at the start of next class don't become the foundation for next week's mistakes.
Learning is social, not solitary.
Students discuss, compare, and reason together. Not alone on a screen.
Instruction is built from their work.
The lesson isn't a generic review. It's built from what the class actually did yesterday.
Feedback cycles are fast.
Students show what they know and receive a quick, targeted, engaging lesson every day.
