2nd Grade Two-Digit Addition worksheets

About this worksheet

Adding two-digit numbers in columns is where most children first carry. Line the numbers up so the ones sit under the ones and the tens under the tens, add the ones first, and when the ones make ten or more, write the ones digit and carry one ten over to the tens column. This worksheet has sixteen sums written in columns, and every one of them needs a carry, with sums that stay under 100.

A few add a one-digit number to a two-digit number, such as 6 + 85, where keeping the digits lined up matters most. Ask your child to say each step aloud: ones first, then regroup, then tens. A forgotten carry leaves the answer ten too small, so estimate with the nearest tens to check.

What your child will learn
