Teaching tips and what to try next

Right for second graders who can already add two two-digit numbers with regrouping. The new challenge is a ones column that may total more than 20, so have your child write the ones total in small digits off to the side before splitting it into tens and ones. Review with Two-Digit Addition With Regrouping or Adding Three Numbers, and stretch to bigger numbers in Three-Digit Addition With Regrouping.

10 versions, each with its own answer key

Same skill and layout, a fresh set of problems in every version, so children can keep practicing without repeating a page. Problems are not repeated between versions unless a skill has only a small number of possible problems (for example, the addition facts within 10).

About this worksheet

Once second graders can add two numbers with regrouping, they are asked to add longer lists, such as the prices of three snacks or the points from four games. This second-grade worksheet gives twelve column addition problems: six with three two-digit numbers and six with four two-digit numbers.

Every number is between 11 and 49, and the problems are mixed on the page, so children switch between three and four addends. Because the ones column adds up several digits at once, the total in that column is often more than 10 and sometimes more than 20. That means children may regroup one ten or two tens into the tens column, which is a new idea for many second graders. Every sum is less than 200. Each of the ten versions has new problems, and each comes with its own answer key.

How to use it: show your child how to add the ones column a little at a time. Look for two digits that make 10 first, then add the rest. For example, in a column with 7, 5, 3, and 8, add 7 + 3 = 10, then 10 + 5 + 8 = 23. Write the 3 under the ones and carry the 2 to the top of the tens column. Saying "two tens" instead of just "two" helps children remember what the carried digit means. When the sheet is done, ask your child to estimate one sum by rounding each number to the nearest ten.

The answer key shows every sum. For more practice, try our Two-Digit Addition With Regrouping worksheet and our Adding Three Numbers worksheet.
