This document provides an overview of a unit on visiting the zoo for children. The unit aims to teach children to classify animals into different groups based on criteria like diet, reproduction, and whether they are vertebrates or invertebrates. Tasks include classifying animals, describing animal body parts, describing individual animals, and creating a book showing what they have learned. The unit builds on prior learning about living things and animals. It will take 8 sessions and use resources like flashcards, posters, and websites to teach vocabulary and classification. By the end of the unit, children will be able to classify animals and produce simple texts describing them orally and in writing.
