Number Bonds to 2 worksheet - Free Printable

Let’s solve this step by step.

We are working with “Number Bonds to 2”. That means we’re looking at pairs of numbers that add up to 2. The diagrams show a top number (always 2) connected to two bottom numbers — those two bottom numbers should add up to 2.

Also, below the diagrams, there are equations to fill in. We’ll use what we know about adding and subtracting to complete them.

First, let’s look at the number bond diagrams:

1. Blue: Top = 2, left = 1 → right must be 1 because 1 + 1 = 2
2. Purple: Top = 2, left = 2 → right must be 0 because 2 + 0 = 2
3. Red: Top = 2, right = 1 → left must be 1 because 1 + 1 = 2
4. Green: Top = 2, right = 0 → left must be 2 because 2 + 0 = 2
5. Orange: Top = 2, left = 0 → right must be 2 because 0 + 2 = 2
6. Dark red: Top = 2, right = 1 → left must be 1 because 1 + 1 = 2
7. Pink: Top = 2, right = 2 → left must be 0 because 0 + 2 = 2
8. Gray: Top = 2, left = 0 → right must be 2 because 0 + 2 = 2

Now, let’s do the equations below:

Left column:
- 2 + □ = 2 → □ = 0 (because 2 + 0 = 2)
- 2 + 0 = □ → □ = 2
- 1 + □ = 2 → □ = 1

Middle column:
- 0 + 2 = □ → □ = 2
- 2 - □ = 1 → □ = 1 (because 2 - 1 = 1)
- 2 - 2 = □ → □ = 0

Right column:
- 1 + 1 = □ → □ = 2
- 2 - □ = 1 → □ = 1
- □ + 0 = 2 → □ = 2

Final Answer:
For the number bonds (left to right, top row then bottom row):
Top row blanks: 1, 0, 1, 2
Bottom row blanks: 2, 1, 0, 2

For the equations (left to right, each column top to bottom):
Left column: 0, 2, 1
Middle column: 2, 1, 0
Right column: 2, 1, 2
