How to use
Paper pause covers this screen while you write and returns to the same step. Back revisits a step. Replay emphasis repeats a visual cue. No animation shows the same mathematics immediately.
Use Tab to move between controls and Enter or Space to activate buttons. Escape closes a dialog. Full screen depends on the browser. There is no timer, score, or student-data collection.
Paper pause
Return whenever you are ready. The lesson stays at this step.
