What this worksheet teaches

• Add multi-digit numbers using column addition with carrying across several places.
• Add numbers with different digit lengths by aligning place values correctly.
• Estimate a total by rounding first, then use it to check the exact answer is sensible.
• Solve multi-step word problems that combine addition with other operations.

How to use this worksheet

For the word problems, ask your child to underline what is being asked before they compute anything. Grade 4 multi-step problems are usually lost at the reading stage, not the adding stage - a correct sum answering the wrong question is the most common wasted effort on these pages.

Sample questions from this worksheet

1. 48 + 77 = ______
2. 309 + 90 = ______

Frequently asked questions

My child understands addition but keeps getting multi-digit answers wrong. Why?

Nearly always alignment or a dropped carry rather than a gap in understanding. Squared paper, one digit per square, and writing carried digits above the columns removes most of these errors immediately.

Should my child still be estimating at Grade 4?

Yes - it is what lets them catch their own mistakes. Rounding to the nearest hundred or thousand first gives a target; if the exact answer is far off, they know to check before you do.

How do we handle adding numbers with different digit lengths?

Line up the place values, not the left edges. Writing a zero in the empty leading places (0,347 for 347) helps some children keep the columns straight while the habit forms.
