Unit Summary
In this unit pupils will review their knowledge from the EYFS of counting in all its forms to and from 10. They will compare and order numbers to 10 practically and will consider the role of zero to represent nothing.
Lesson Summary
You will learn to order the numbers from zero to 10.
Key Notes
- Know the order of numbers will not change and will always be said in the same order (stable-order principle).
- Know we can order numbers by counting.
- Know we can order numbers using our knowledge of 'greater than' and 'less than'.
Vocabulary To Learn

- Largest: The largest number is the one that comes after all the others in the count.
- Greater than: Bigger / larger in value or size.
