Tips & Best Practices
- Keep yellow long enough for children to finish a sentence or pencil stroke.
- Use green for work and red for listening rather than mixing meanings mid-week.
- Practice the three phases during low-stakes games before using during assessments.
Common Mistakes to Avoid
- Switching red to mean punishment instead of a neutral stop signal.
- Using very short yellow phases that trap students mid-action and feel unfair.
- Placing the display behind the teacher where half the class cannot see the active color.
Frequently Asked Questions
What do the three colors mean on this timer?
Green is active work time, yellow is a finish-up warning, and red is a full stop or listen phase.
Can I change how long each light lasts?
Yes. Pick presets or enter custom seconds for each phase sequence.
Is this useful for crossing guard lessons?
Yes. Short green and yellow presets mirror common street-crossing practice drills.
Will color-blind students be left out?
Pair colors with position labels and verbal cues; digits also show remaining seconds.
Does it make sound when the light changes?
Optional alerts can signal phase changes; mute if your setting requires silence.
Can I run it on a phone at the gym?
Yes. Open the page and prop the phone where players can see the active light.
Is the traffic light timer free?
Yes. TimerClock offers it at no charge in your browser.
How is this different from a visual ring timer?
Traffic lights emphasize stop-go rules with discrete phases instead of a continuous shrinking ring.
