Adding 10 to a 2-digit Number Worksheets

In these First Grade math worksheets, students practice adding 10 to a 2-digit number (a number less than 100). When adding 10 to a number, increase the tens digit by 1 and keep all the other digits the same. If the tens digit is a 9 then change the 9 to a 0 and increase the hundreds digit by 1.

Key Points:

• Adding 10 is essentially adding 1 to the tens place.
• The ones place remains the same because we’re not adding anything to it directly.
• This concept applies to any multiple of 10 (20, 30, 40, etc.).
