      Explain that a whole can represent a group of objects

      Lesson details

      Learning outcome

      I can explain that a whole can represent a group of objects.

      Key learning points

      1. A whole can be represented by a group of objects

      Keywords

      • Whole - All of something. Complete.

      • Part - A piece of a whole.

      • Group - A set of objects.

      • Whole group - A group of objects that form a whole set.

      Common misconception

      Children may not realise that an object can represent a whole as well as a part of a whole group.

      Explore real life examples of wholes as individual objects as well as sets of objects, e.g. sweets, eggs, chocolates, pencils in boxes etc.

      Teacher tip

      It can be tricky to understand that an object can be a whole as well as part of a larger whole, and that wholes can look different. The parts may be different, but emphasise that they are always smaller than the whole.
