This document outlines a CLIL lesson plan for teaching primary school students about animal classification. The aims are for students to learn to talk about animals' eating habits, physical appearance, and how to classify animals into groups. The lesson involves students watching a video about animals, classifying animals into categories like mammals and birds, and describing an animal's appearance and diet.
