## Lesson details

### Key learning points

1. A whole can be split into two or more parts in different ways.
2. The parts may look different.
3. Each part will be smaller than the whole.
4. The parts can be combined to make the whole.

### Common misconception

Children may think that smaller wholes are only a part and that parts all have to look the same.

Use a variety of real objects to demonstrate wholes and parts split and combined in different ways.

### Keywords

• Whole - All of something. Complete.

• Part - A piece of a whole.

• Split - To break up a whole into parts

• Combine - To put parts together to make a whole

Use lots of real objects, e.g. fruit to demonstrate splitting and combining wholes and parts in different ways. Ask questions such as 'Is this the whole?' and 'Could this be a part?' to promote deeper thinking and reinforce the vocabulary.
