2nd Grade Add Up to Four Two-Digit Numbers worksheets

About this worksheet

Adding three two-digit numbers is two-digit addition done twice over. Stack the numbers with the ones under the ones, add the ones column first, and carry the tens to the next column. With three numbers the ones often make 20 or more, so the carry can be 2, not just 1. This worksheet has sixteen sums, each with three two-digit numbers stacked in a column.

Ask your child to add the first two numbers, then add the third, or to look for two ones that make ten. Leave room next to each sum for carrying, and check the answer by estimating with the nearest tens. Adding three numbers in one column is also good practice for the word problems that come later, where a child often has to combine several amounts.

What your child will learn

• Add three two-digit numbers in a column
