Grade 2 Math: 3-Digit Plus 2-Digit Addition Worksheet

OVERVIEW

Grade 2 students reach a pivotal milestone when they transition from simple sums to multi-digit addition. This worksheet provides essential practice for adding two-digit numbers to three-digit numbers. This specific skill helps children understand place value across the ones, tens, and hundreds columns while introducing the logic of regrouping (or "carrying"). By working through these 30 vertically arranged problems, students develop the fluency and confidence needed for more complex arithmetic in higher grades.

STEP-BY-STEP SOLVED EXAMPLES

Example 1: 338 + 11

First, align the numbers by their place value. Start in the ones column: 8 + 1 = 9. Move to the tens column: 3 + 1 = 4. Finally, the hundreds column remains: 3 + 0 = 3. The total is 349.

Example 2: 341 + 19

In the ones column, 1 + 9 = 10. Write down '0' and carry '1' to the tens column. In the tens column, add 4 + 1 plus the carried 1 to get 6. The hundreds digit stays 3. The sum is 360.

Example 3: 419 + 24

Begin with the ones: 9 + 4 = 13. Write '3' and carry '1' to the tens place. Next, add the tens: 1 + 2 + 1 (carried) = 4. The hundreds digit is 4. The final answer is 443.

TEACHER & PARENT TIPS

Encourage students to use a highlighter to mark the "ones" column if they struggle with alignment. It is also helpful to remind learners to always start adding from the right side (ones place). If regrouping is a new concept, provide physical base-ten blocks to visualize why ten ones become a single ten-rod in the next column. Consistent practice with vertical layouts like this one reduces placement errors and builds calculation speed. For advanced learners, challenge them to estimate the answer before solving to improve their number sense.
