When I student taught I worked with a wonderful group of children in Waterbury, CT in a transitional first grade. The class provided more sheltered instruction for students, many learning English, who did not meet Kindergarten readiness benchmarks...after Kindergarten.
I had them write poems about carnivals, rain, and frogs. The students found words by writing with their senses. Explaining what you see, hear, feel, and touch can provide a roadmap for any writer stuck on.getting started.
I teach the same lesson in college. Like metaphors, writing with the senses belongs in every author's toolbox so they can reach in a grasp on to a concrete idea.
Found an easy explainable lesson plan in the article Teaching Descriptive Writing through Visualization and the Five Senses by Katherine Carter
