Why Replay My Lesson
Your whiteboard should
remember how you taught.
Not just the finished answer. Replay My Lesson is designed around the sequence of thinking that helped students get there.
Keep every step visible
Zoom into dense problems, move naturally between pages, and let students follow your pointer and ink.
Record the reasoning
Capture the board, your narration, and teaching stops so a complete explanation can be replayed later.
Founding teacher beta
Use it like you teach.
Tell us what gets in the way.
Replay My Lesson is being shaped with practicing teachers. Try a real mini-lesson—not just a few scribbles—and send feedback from inside the whiteboard.
