What are 3-digit addition worksheets?
3-digit addition worksheets are printable math activities that involve adding numbers with three digits. For example, 123 + 456 = 579 is a 3-digit addition problem.
These worksheets can have different formats and levels of difficulty, depending on the skills and goals of the students. Some common types of 3-digit addition worksheets are:
-
Adding without regrouping (or carrying): This means that the sum of each column is less than 10. For example;
Adding with and without regrouping: This means that some columns require regrouping, and some don't. For example, 123 + 456 = 579. In this case, you only have to regroup in the tens column.
-
Adding with regrouping (or carrying): This means that the sum of one or more columns is greater than 10. For example, 123 + 287 = 410. In this case, you must regroup (or carry) the extra digit to the next column.
In the ones column, 3 + 7 = 10. You write down 0 and carry the 1 to the tens column.
Then, add the tens column: 1 + 2 + 8 = 11.
You write down 1 and carry the 1 to the hundreds column.
Finally, you add the hundreds column: 1 + 1 + 2 = 4.
You write down the final answer: 410.
