Largest/smallest number possible
Key Notes :
Largest Number :largest number is determined by the digits in the number. The digit in the highest place value (e.g., hundreds, thousands) contributes the most to making the number larger.


Smallest Number : mallest number is determined by the digits in the number, with the smallest digits (e.g., zeros) in the lowest place values making the number smaller.


Activities and Examples:
- Largest Number:
- Ask students to create the largest number possible using given digits (e.g., using 1, 3, 5, and 7 to make 7,531).
- Practice ordering numbers from smallest to largest and vice versa


- Smallest Number:
- Encourage students to identify the smallest number in a set.
- Use real-world examples like counting objects, where zero represents no objects present.
