Formal:
* To the teacher: "Good morning/afternoon, [Teacher's name]. I'm ready to present my report."
* To the class: "Good morning/afternoon, class." (said after addressing the teacher)
Slightly less formal (but still respectful):
* To the teacher: "Good morning/afternoon, [Teacher's name]. I'd like to begin my report now."
* To the class: "Hello, everyone." (said after addressing the teacher)
Things to avoid:
* Informal greetings like "Hey" or "What's up?"
* Ignoring your teacher and addressing the class first. Always acknowledge your teacher first.
* Mumbling or speaking too quietly. Project your voice so everyone can hear.
Remember to maintain eye contact with your teacher and class throughout your greeting and your report. A confident and polite greeting sets a positive tone for your presentation.
