Commutative Property of Addition Worksheets for Kids Online - Free Printable

The task involves using the Commutative Property of Addition, which states that changing the order of the numbers being added does not change the sum. Mathematically, this is expressed as:

\[
a + b = b + a
\]

We need to fill in the missing numbers based on the images and the commutative property.

---

Step 1: Analyze the First Problem

#### Image:
- On the left: 3 cupcakes + 2 cakes.
- On the right: 2 cakes + ? cupcakes.

#### Numbers:
- Left side: \( 3 + 2 \)
- Right side: \( 2 + ? \)

Using the commutative property:
\[
3 + 2 = 2 + 3
\]

So, the missing number is 3.

#### Final Answer for the First Problem:
\[
3 + 2 = 2 + 3
\]

Step 2: Analyze the Second Problem

#### Image:
- On the left: 5 soccer balls + 1 beach ball.
- On the right: 1 beach ball + ? soccer balls.

#### Numbers:
- Left side: \( 5 + 1 \)
- Right side: \( 1 + ? \)

Using the commutative property:
\[
5 + 1 = 1 + 5
\]

So, the missing number is 5.

#### Final Answer for the Second Problem:
\[
5 + 1 = 1 + 5
\]

---

Step 3: Analyze the Third Problem

#### Image:
- On the left: 6 carrots + 4 apples.
- On the right: 4 apples + ? carrots.

#### Numbers:
- Left side: \( 6 + 4 \)
- Right side: \( 4 + ? \)

Using the commutative property:
\[
6 + 4 = 4 + 6
\]

So, the missing number is 6.

#### Final Answer for the Third Problem:
\[
6 + 4 = 4 + 6
\]

---

Final Answers:

1. \( 3 + 2 = 2 + 3 \)
2. \( 5 + 1 = 1 + 5 \)
3. \( 6 + 4 = 4 + 6 \)

Boxed Final Answer:

\[
\boxed{3, 1, 5, 6, 4}
\]
