Do not give longer or complicated instructions only orally, especially not in lower level classes. Instead write the instructions on a notecard and display them using a notecard displaying tool. Advantages:
- Students can follow what you are saying by reading the notecard
- Students who cannot hear you can still read the instructions
- Less explaining needed thus less Teacher Talking Time 🙂
- Fewer questions will arise and thus there will be more time left for the actual activity.
