Understanding the world covers three areas; people and communities, the world and technology. In this area, children learn all about themselves, their families, friends and other cultures, and the world around them. Children recognise similarities and differences in relation to places, objects, materials and living things and can talk about features of their own immediate environment and how environments might vary. They make observations of animals and plants, explaining why some things occur, and talk about changes. Children recognise that a range of technology is used in places such as homes and schools and select and use technology for particular purposes.
