Prepositions [In, On, At]
This ppt explores many aspects of the prepositions, not only when they are used, but when to add "the" and "a". It's very specific for the book Interchange Intro Unit 16, and it explores some of the vocabulary given in the book and also the correct use of the prepositions.
