Hi Natalia-

Buen trabajo! In English we say, "go shopping" for "ir de compras." Aqui seria "we went shopping" porque estas hablando del pasado.

Tambien es importante usar "his" and "her" dependiendo de quien estas hablando.  Por ejemplo, "Es su casa" seria "It's her house" si hablas de una mujer o "It's his house" si hablas de un hombre.

Good luck--keep writing!

Tomorrow I will be visiting to my grandmother in his house.

Tomorrow I will visit [  ] my grandmother in her house. ( [  ] = quité algo).

No usamos el "personal a" en el inglés.  "Voy a visitar a mi abuela" = "I'm going to visit my grandmother."  "Él llama a su padres" = "He calls his parents".

Tomorrow I will visit my grandmother at/in her home. (home es poco más natural)
