It looks like you've uploaded a math worksheet focused on
addition and
number sense, specifically designed for young learners (likely kindergarten or early elementary). The task involves:
1.
Changing the order of addends in addition problems (commutative property).
2.
Coloring cubes to represent the numbers.
3.
Writing the sum of each equation.
Let's go through the worksheet step by step and solve it.
---
🔢 Problem 1:
2 + 3 = 5
- You are to color 2 red cubes and 3 green cubes (or vice versa, depending on instructions).
- Then write the sum:
5
- Now, change the order:
3 + 2 = 5
- Color 3 red and 2 green (or follow the key at the bottom).
- Sum is still
5
✔ Answer:
`2 + 3 = 5` → `3 + 2 = 5`
---
🔢 Problem 2:
5 + 2 = ___
- Add: 5 + 2 =
7
- So, write: `5 + 2 = 7`
- Now reverse: `2 + 5 = 7`
- Color 5 cubes and 2 cubes accordingly.
✔ Answer:
`5 + 2 = 7` → `2 + 5 = 7`
---
🔢 Problem 3:
2 + 1 = ___
- 2 + 1 =
3
- Reverse: `1 + 2 = 3`
✔ Answer:
`2 + 1 = 3` → `1 + 2 = 3`
---
🔢 Problem 4:
4 + 2 = ___
- 4 + 2 =
6
- Reverse: `2 + 4 = 6`
✔ Answer:
`4 + 2 = 6` → `2 + 4 = 6`

🎨 Coloring Key:
At the bottom:
-
Red apples and
green apples: Use red for one number, green for the other.
-
Blue pens and
red pens: Possibly another example for coloring — but not used in the main problems.
So when coloring:
- For `2 + 3`, color 2 cubes red, 3 green (or as per key).
- For `3 + 2`, reverse: 3 red, 2 green.
- Same logic applies to others.

✔ Final Answers:
| Original | Reversed | Sum |
|--------|---------|-----|
| 2 + 3 = 5 | 3 + 2 = 5 | 5 |
| 5 + 2 = 7 | 2 + 5 = 7 | 7 |
| 2 + 1 = 3 | 1 + 2 = 3 | 3 |
| 4 + 2 = 6 | 2 + 4 = 6 | 6 |

💡 Concept Explained:
This worksheet teaches the
commutative property of addition:
>
a + b = b + a
No matter the order of the numbers, the sum stays the same.

✔ How to Complete the Worksheet:
1. Fill in the blanks with correct sums.
2. Draw or color the cubes according to the numbers (e.g., 2 red, 3 green).
3. Write the reversed version of each addition problem.
4. Ensure all sums match.
