Stopwatch - Virtual Manipulative

Measure Elapsed Time with Precision

A simple, high-visibility digital stopwatch for timing classroom activities and physical experiments.

• How to Use: Use the Start, Stop, and Lap buttons. The large display is ideal for projecting onto a whiteboard for the whole class.
• Classroom Idea: Time how long it takes for a group to solve a math puzzle, then challenge them to beat their “Lap Time” in the next round.
