How to Do 2-Digit Column Addition Without Regrouping in Grade 1
FAQs on Class 1 Maths Worksheet: Add Two 2-Digit Numbers in Columns (No Regrouping)
1. What is 2-digit addition without regrouping?
2-digit addition without regrouping is a basic method of adding two double-digit numbers where the sum of the digits in each column (both ones and tens) is 9 or less. This is often called no carry addition because you do not need to carry over any values to the next place value column.
2. How do you teach addition in columns to a Class 1 student?
To teach addition in columns to a Class 1 student, you can follow these simple, step-by-step instructions:
- Step 1: Arrange the numbers vertically, aligning the ones and tens digits properly in their columns.
- Step 2: Start by adding the digits in the ones column on the right.
- Step 3: Next, add the digits in the tens column.
- Step 4: Write the sum of each column directly below the line to get the final answer.
3. What is the difference between regrouping and no regrouping in addition?
The key difference between regrouping and no regrouping is how you handle sums greater than 9 within a column.
- Addition without regrouping: The sum of the digits in each column is 9 or less. For example, in 23 + 14, the ones (3+4=7) and tens (2+1=3) do not require carrying.
- Addition with regrouping: The sum in a column is 10 or more, so you must “carry over” the tens digit to the next column. For example, in 28 + 15, the ones column (8+5=13) requires you to write '3' and carry '1' to the tens column.
