Giving directions to a specific location seems to be an area that even more advanced Spanish students have trouble with. After Spanish II or III, most college level Spanish courses concentrate on literature. Knowing the plot of a famous Cervantes novel is not going to help you when attempting to communicate rapidly with an ornery cab driver or local for directions.
In your text, you will have covered many of the prepositions needed to describe the location of places, but it is hard to put it all together to be able to give directions clearly. This is a good subject to work on since anyone who ever travels to a Spanish speaking country will probably get into one of these kinds of conversations.
Pick a random location in your town. It can be the local library or the supermarket. Now describe how you would get there from where you live. Next, describe how you would get there from across town. The point is to work on a variety of words used in giving and following directions. You want to be able to express key terms, such as across the street, cross the bridge, pass the store, get on the highway, go down this street.
Most Spanish students, if given time, could come up with ways to convey these ideas in Spanish. Most of the time a language learner, especially one not living in a country that speaks the target language, will come up with some awkward sounding sentences. That is OK. Write these sentences out and see what you come up with. Now, it is time to see how a native speaker would say the same thing.
You do not want to be lost on a busy street trying to ask a local for directions sounding like you are quoting the Spanish equivalent of a Shakespeare play.
