Common phrases when a classroom changes
These simple sentences are useful for asking where the new classroom is, confirming times, and explaining yourself.

Qual é o novo horário?
Ficou no mesmo prédio?
O professor trocou? Quem vai dar a aula?

How to ask for directions
Beginners often need to ask where the new classroom is. Use polite, short questions and follow simple answers.
Com licença, onde é a sala 105?
Você sabe onde mudou a aula de matemática?
Tem um mapa do prédio?
Short replies you might hear:
A sala 105 fica no segundo andar.
Siga pelo corredor à esquerda e vire à direita.
É na sala ao lado da biblioteca.
Confirming schedule and teacher
When classes move, verify the time and who is teaching. Use these short, clear questions.
A aula é às 14h?
Quem vai dar a aula hoje?
O professor está aqui?
Helpful replies:
Sim, continua às 14h.
Hoje a professora Ana vai dar a aula.
O professor ainda não chegou.
Practical short dialogues
Short dialogues show realistic interactions. Read them aloud to practice pronunciation and rhythm.
Dialogue 1 – Finding the new room
Com licença, onde fica a sala 301?
Fica no terceiro andar. Sobe pela escada e é a segunda porta à direita.
Obrigada!
Dialogue 2 – Class moved and time check
A aula de história mudou de sala?
Sim, agora é na sala 210. Continua no mesmo horário, às 10h.
Certo, vou para lá.
Dialogue 3 – Teacher change
Oi, a aula já começou?
Ainda não. Hoje a professora Carla vai substituir o professor João.
Ah, entendi. Obrigado.
Polite expressions and classroom etiquette
When you enter a new classroom, be polite and clear. Use simple greetings and apologies if you’re late or lost.
Desculpe, estou atrasado.
Com licença.
Bom dia / Boa tarde / Boa noite.
If you need to ask the teacher a question:
Professor(a), posso entrar?
Posso sentar aqui?
Common teacher replies:
Pode entrar.
Sim, sente-se onde quiser.
Short messages and announcements
Students and staff often send quick messages about room changes. Learn short phrases for texts or notices.
Aula de química: sala 108.
Troca de sala: história para a sala 206.
Atenção: a reunião foi transferida para o auditório.
Examples of simple student messages:
Gente, a aula mudou para a sala 402.
Alguém sabe onde é a sala 402?
Useful verbs and mini grammar tips
Understanding a few verbs helps you form sentences about changes.
ficar – to be located, to remain. Use to say where the room is: A sala fica no primeiro andar.
mudar / trocar – to change. Use when classes or rooms are switched: A aula mudou de sala.
chegar – to arrive. Use for the teacher or students: O professor chegou.
Beginner grammar tips:
Use simple present to talk about scheduled changes: A aula começa às 9h.
Use past with chegar to say someone arrived: Ele chegou atrasado.
Common beginner mistakes and how to avoid them
Beginners often mix vocabulary or forget polite phrases. Here are common errors and corrections.
Mistake: Saying Onde está a sala 204? when you mean where it is located. Better: Onde fica a sala 204?
Mistake: Using trocar incorrectly. If you mean the class has been moved, say A aula mudou de sala rather than A aula trocou sala.
Mistake: Forgetting to use com licença before interrupting. Always say Com licença when asking someone in a corridor.
Tip: Use horário for schedule, not tempo. Tempo means weather or time in a different sense.
Practical scenarios and model phrases
Here are short role-specific phrases for students, teachers, and staff in classroom-change situations.
Student: Com licença, a aula de inglês mudou de sala?
Teacher: Sim, a aula passou para a sala 305 hoje.
Staff at reception: O novo horário e a sala estão no quadro de avisos.
Student asking a friend: Onde a gente se encontra? Na entrada do prédio ou na sala nova?
Student confirming online: Pessoal, confirmando: a aula é às 16h na sala 207?
Simple tips to sound natural
Keep sentences short, use polite expressions, and listen for keywords like sala, horário, andar, and professor. Repeat key words using sala and horário when asking or confirming. Smile and use Com licença to start questions.
When in doubt, ask two short questions rather than one long one: Onde fica a sala? O horário mudou?
Use numbers clearly: falar vinte e quatro or simply vinte quatro for room numbers like 24. For times, use 14h for 2 PM (spoken: quatorze horas or duas da tarde for informal).

Where to see these phrases in real life

Signs often use concise language: Sala 307 — Aula transferida. Learn to interpret these announcements quickly by spotting the main words: sala, transferida, troca, horário.
