Solve problems by comparing sets of objects
I can solve problems by comparing the number of objects in two sets.
Lesson details
Key learning points
- Make comparisons between 2 sets of the same objects.
- Make comparisons between 2 sets of different objects.
- Count the different objects separately.
- One set can contain more or fewer objects than the other.
- 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.
