Adding 2-Digit and 1-Digit Numbers – Worksheet for Class 3

Addition with regrouping, also known as carrying over, is when the sum in the ones column is 10 or more. In this case, you carry the 'tens' part of the sum over to the tens column.

Example: 28 + 5

• Step 1: Add the ones: 8 + 5 = 13. Write down '3' in the ones place.
• Step 2: 'Carry over' the '1' (from 13) to the tens column.
• Step 3: Add the tens: 2 + 1 (the carried-over number) = 3.
• Step 4: The final answer is 33. This skill is crucial for adding 2 digit plus 1 digit numbers correctly.

There are several effective ways for a Grade 3 student to practice this skill, which are often included in worksheets. These methods build both understanding and speed.

• Vertical Addition: Writing the numbers one above the other to practice adding by place value.
• Horizontal Addition: Solving sums written in a line, like 52 + 7, to build mental addition skills.
• Number Line Addition: Using a number line to visually jump forward and find the sum.
• Practice Sums: Regularly solving a variety of problems, including both with and without regrouping.
