Expand the number

Expand the 2-Digit Number Worksheets focus on breaking down two-digit numbers into their place values. Students will:

– Decompose two-digit numbers into tens and units, e.g., 47 as 40 + 7.
– Practice writing numbers in expanded form to understand place value.
– Reinforce the concept of place value and number structure.

These worksheets help build a strong foundation in understanding and using place value in two-digit numbers.
