🔍 Explanation:
This worksheet tests
place value understanding. Each number is broken down into its component parts based on place values (like ten thousands, thousands, hundreds, tens, ones). To write in
standard form, we simply
add all the parts together.
For example:
- $90000 + 9000 + 900 + 90 + 9$ → All digits are 9, so it becomes
99,999.
This helps students understand how numbers are built using place values.
