This document provides a learning package on parallelism in English for high school students. It outlines three objectives for students: 1) Identify correct parallel sentences, 2) Value balancing their work, and 3) Participate in a cooperative activity called "Pass the Cube". The package then discusses the concept of parallelism through examples and an activity where students fix sentences that lack parallel structure by rewriting them with parallel elements. Maintaining parallel structure is important for preventing awkwardness, promoting clarity, and creating concise writing.
