Determine whether prepositional phrases are describing when or where with this worksheet.   Students will be given a selection of phrases they will join to when or where based on what it would add to a sentence.   The following task will have students create their own prepositional phrases given a base sentence. This will allow them to see how a sentence can be changed to add additional information in multiple ways.   Finally, students will list three prepositions that can be used for when and three prepositions for where.   Choose to print and place in write and wipe sleeves for small group situations.
