Printable addition worksheet for kids focusing on adding 1 to numbers 0 through 9.

Let’s solve each addition problem step by step.

We are adding 1 to numbers from 0 to 9, and also adding numbers from 0 to 9 to 1. Remember:
Adding 1 means you go up by one number on the number line.
Also, addition is commutative — that means 3 + 1 is the same as 1 + 3.

Let’s do them in order:

Left Column:

1 + 1 = 2
2 + 1 = 3
3 + 1 = 4
4 + 1 = 5
5 + 1 = 6
6 + 1 = 7
7 + 1 = 8
8 + 1 = 9
9 + 1 = 10
0 + 1 = 1

Right Column:

1 + 0 = 1
1 + 1 = 2
1 + 2 = 3
1 + 3 = 4
1 + 4 = 5
1 + 5 = 6
1 + 6 = 7
1 + 7 = 8
1 + 8 = 9
1 + 9 = 10

All answers match their pairs (like 2+1 and 1+2 both equal 3), which makes sense!

Final Answer:
1 + 1 = 2
2 + 1 = 3
3 + 1 = 4
4 + 1 = 5
5 + 1 = 6
6 + 1 = 7
7 + 1 = 8
8 + 1 = 9
9 + 1 = 10
0 + 1 = 1
1 + 0 = 1
1 + 1 = 2
1 + 2 = 3
1 + 3 = 4
1 + 4 = 5
1 + 5 = 6
1 + 6 = 7
1 + 7 = 8
1 + 8 = 9
1 + 9 = 10
