This is one of my creative writing students' very favorite activities. First, I explicitly teach the literary term sensory details using the Frayer model vocab chart and this fun YouTube video https://www.youtube.com/watch?v=3sSq6s5J1iQ
Second, we go over the excerpt from "Holes" to annotate for sensory details (included in the worksheet). Then, I pull out a big jar of pickles to pique students' interest. I go over the instructions on the worksheet and set students loose to practice sensory details using the worksheet. I cut up small pieces of pickles and let students take a piece or two to help them be inspired for the sensory details they'll write (they love this part). We make the assignment a big contest and whoever comes up with the best and most creative sensory detail gets the leftover pickle juice as a prize (sounds silly, but it really works). After students have had about a half hour to do the writing portion of the assignment, we do a whip around and each student picks their one best sensory detail to share with the class.
