Use visual aids like number charts and manipulatives (like blocks) to demonstrate how numbers are formed. Practice writing numbers together, starting with simple numbers and gradually moving to more complex ones. Encourage them to break down numbers into hundreds, tens, and units for better understanding.
3. Why is understanding 3-digit numbers important for children?
