Welcome to lesson number 42, where students learn how to describe a person’s physical appearance, focusing on key aspects such as face, hair, and eye color. The lesson is divided into three parts: watching a video to learn suitable vocabulary, engaging in exercises involving coloring or drawing, and completing a listening exercise where students match stories to observed images. The lesson also covers how to describe different age groups, using terms like “mezza età” (middle-aged) and diminutives like “vecchietto” and “vecchietta” for older individuals.
