1.Which one is correct?

Tocamos el piano.
Jugamos el piano.
Tocamos al piano.

I think it is the Tocamos el piano because if it was jugamos then it would have to have "al" in front of piano. Piano is masculine so it couldn't be Tocamos al piano.
2. Which is correct?
Toco las cartas.
Juego a las cartas.
Juego las cartas.
I think it is "Juego a las cartas."

Correct! Tocamos el piano.

tocar means "to touch" and when you "play" any instrument, you must touch it!

The second is also correct! to play AT a game = jugar a

Thank you

1. You are correct! The correct sentence is "Tocamos el piano." In Spanish, the verb "tocar" means "to play" when referring to musical instruments. Since "piano" is a masculine noun, we use the article "el" to match the gender. If we were using the verb "jugar" (to play) instead, we would indeed need to use the preposition "a" before the instrument, resulting in "Jugamos al piano."

2. Good job! The correct sentence is indeed "Juego a las cartas." In Spanish, the verb "jugar" is used to express the action of playing games or sports. When referring to a specific game, like "las cartas" (cards), we use the preposition "a" to indicate the game being played. So the correct structure is "jugar a + [game]," resulting in "Juego a las cartas."
