Conversely - when you take a class expecting it to end at 8pm and the lesson drags on until 8:20pm. The situation can be unpleasant for multiple parties which is why classroom time management is so important. And, if you find yourself consistently running late, it might be time to make a change.

Anyway, let’s get down to some tips for classroom time management:

Wear a watch, have a clock conveniently placed for repeated checking, or have a time-keeping device nearby that you can readily check without disrupting class
Provide more opportunities for independent play. If you’re a person that relies on your phone or computer to tell you what time it is, you need opportunities to check it. When you’re a teacher that relies on teacher-dependent practice, that makes it tough. Creating occasions for students to dance on their own such as when you play music also allows you to check in with your co-teacher, review the curriculum and class goals, and strategize how to end on time.
Have an arsenal of fun moves you can quickly teach that support your curriculum goals. For instance, we have Break & Shake, Points, Twistaround, and others we can teach in under 10 minutes, sometimes under 5 minutes.
Accept not everyone will get what you’re teaching perfectly and be okay with this. Your role is to also provide them the knowledge and skills necessary to (hopefully) practice outside of class.
Make a change. If you’re constantly running late, starting late, or know that your scheduled classroom time is never enough to support your goals, something needs to change. Announce that classes start later, deliberately schedule your classes to be 75 minutes long instead of 60, or even re-evaluate what and how you teach.

Everyone’s time is valuable and ought to be respected.
