Formal:
* "Witamy w klasie pierwszej!" - This is the most common and formal way to greet students entering the first grade. It translates literally to "Welcome to the first class!"
* "Witamy w roku szkolnym 2023/2024!" - This would be more appropriate if welcoming students to the whole school year, not just the first grade. It translates to "Welcome to the 2023/2024 school year!"
Informal:
* "Witajcie w pierwszej klasie!" - This is a less formal way to greet students, suitable for a teacher or someone familiar with the children. It translates to "Welcome to the first class!"
* "Witajcie w roku szkolnym!" - A more casual way to welcome students to the whole school year, meaning "Welcome to the school year!"
Other options:
* "Miło Was widzieć w pierwszej klasie!" - This translates to "It's nice to see you in the first class!" and is a friendly and welcoming phrase.
* "Zaczynammy nowy rok szkolny!" - This translates to "We're starting a new school year!" and is a way to announce the beginning of the year.
The best option depends on the context and who you are speaking to. Remember to use a friendly and enthusiastic tone when welcoming students to the first grade!
