      Lesson details

      Learning outcome

      I can name and group a wide variety of common animals, including fish, amphibians, reptiles, birds and mammals.

      Key learning points

      1. Different animals have different characteristics and these can be used to group them into broad categories
      2. Some common animal groups are fish, amphibians, reptiles, birds and mammals
      3. Animals can be identified and grouped using classification skills

      Keywords

      • Mammal - A mammal is a warm-blooded animal that gives birth to live young and has hair or fur.

      • Fish - A fish is a cold-blooded animal that has fins and a tail and uses gills to breathe underwater.

      • Bird - A bird is a warm-blooded animal that lays hard shelled eggs and has feathers.

      • Reptile - A reptile is a cold-blooded animal that lays eggs and has dry, scaly skin.

      • Amphibian - An amphibian is a cold-blooded animal that has moist skin, lays eggs and can live on land and in water.

      Common misconception

      Pupils may think that all sea-dwelling animals are fish or that only birds can fly.

      Explain, with examples from the lesson, that animals are classified based on their physical features, not where they live or how they move.

      Teacher tip

      Encourage children to think about how their favourite animals or pets would be classified using the criteria covered in the lesson.
