This resource is great for two reasons. One, it offers a number of excellent examples that really highlight the art of show not telling. Two, the examples in each "Telling" category can be placed in front of your students so they have a chance to creatively practice their show-don't-tell skills.
This writing packet provides examples and handouts for students to practice showing not telling. Also included in the packet is an extensive list of writing exercises from which students can practice their show-don't-tell knowledge.
