Direct and indirect objects

When I study spanish in the school my teacher asked me these questions

Doy la pelota a Ramón.

What (thing) are you giving? The ball. 

Ok, so the thing that you are giving, in this case, the ball, it´s the direct object.

Le doy la pelota a Ramón.

who are you giving (the thing)?

I´m giving the ball to ramon.

I´m giving it to him

In spanish we use "le" like indirect object instead of "to him", so "le" is the indirect object.

I hope this would be useful for you. :)

Gracias.

Sí, en español podemos utilizar DOS complementos indirectos para reforzar la acción. 

Así, solemos decir:

A mi amiga le le gusta mucho hacer deporte (A mi amiga y le)
