Suggested Lesson Plan: Animal Classification

There are many different types of animals in the world, what we can see in Hong Kong are just a small sector of them. Thus, students may find difficulty in learning the classification of animals. Films from TWIG can help students visualise different features and characteristics of the animals, as if they are observing these animals in real life.
