This would be a great poster to hang in a classroom as part of walls that teach! Prepositions are something that may be a little abstract for students to understand, but this is a great visual representation of what they are. This could work both on visual representation and skill within language arts. Students could then make up their own poster for another type of word, such as a verb.
