The document provides examples of how to use prepositions like "on", "next to", "across from", "between", and "on the corner of" to give directions and describe locations. It gives sample sentences like "The school is on Fifth Street" and "The bank is across from the post office." It then asks questions to prompt using these prepositions, such as "Where is the post office?" and provides possible answers using the prepositions, like "It is on Main Street. It's across from the bank." The document teaches how to use these common prepositions to effectively give and understand directions.
