## Lesson details

### Key learning points

1. Make comparisons between 2 sets of the same objects.
2. Make comparisons between 2 sets of different objects.
3. Count the different objects separately.
4. One set can contain more or fewer objects than the other.
5. Both sets can contain the same number of objects.

### Common misconception

Children may think that bigger objects, or objects that are spread out have a greater value.

Emphasise that we are counting the number of objects and it does not matter about the size or position.

### Keywords

• Same - two or more things are identical

• Different - non-identical

• More than / greater than - has a greater amount / more items.

• Less than / fewer than - has a lesser amount / fewer items.

• Equal to - exactly the same amount or value

The lesson starts to make comparisons between sets of objects. Provide opportunities for practical comparison of a variety of objects.
