One-Digit Addition; With Regrouping (B) Worksheet for 1st - 2nd ... - Free Printable

Explanation:
We are adding two one-digit numbers in each column. We need to add them together and write the result below.

Let’s go column by column from left to right.

First column:
3 + 4 = 7

Second column:
6 + 6 = 12

Third column:
8 + 5 = 13

Fourth column:
8 + 7 = 15

Now let’s check the second row:

First column:
9 + 5 = 14

Second column:
9 + 3 = 12

Third column:
5 + 9 = 14

Fourth column:
3 + 9 = 12

Now the third row:

First column:
4 + 6 = 10

Second column:
6 + 2 = 8

Third column:
3 + 7 = 10

Fourth column:
3 + 5 = 8

Now we write the answers for each column:

Column 1: 7, 14, 10
Column 2: 12, 12, 8
Column 3: 13, 14, 10
Column 4: 15, 12, 8

Final Answer:

14, 12, 14, 12
10, 8, 10, 8
