Odd and Even Numbers Tree: A fun math activity worksheet for children to identify and color odd and even numbers on a tree.

Let’s solve this step by step.

We need to sort the numbers on the tree into two groups:
- Odd numbers → color them with the red crayon
- Even numbers → color them with the green crayon

First, let’s list all the numbers we see on the apples in the tree:

From top to bottom, left to right (as best as we can read):

20, 13, 8,
5, 15, 12,
10, 14, 11,
6, 9,
4, 7,
3, 2, 1

Wait — let me double-check and make sure I didn’t miss any or misread.

Looking again carefully:

Top row: 20, 13, 8
Next: 5, 15, 12
Then: 10, 14, 11
Then: 6, 9
Then: 4, 7
Bottom: 3, 2, 1

That’s 16 numbers total. Let’s write them in a list:

Numbers: 20, 13, 8, 5, 15, 12, 10, 14, 11, 6, 9, 4, 7, 3, 2, 1

Now, let’s go one by one and decide if each is odd or even.

Remember:
- Even numbers end in 0, 2, 4, 6, or 8 → divisible by 2
- Odd numbers end in 1, 3, 5, 7, or 9 → not divisible by 2

Let’s check each:

1. 20 → ends in 0 → even
2. 13 → ends in 3 → odd
3. 8 → ends in 8 → even
4. 5 → ends in 5 → odd
5. 15 → ends in 5 → odd
6. 12 → ends in 2 → even
7. 10 → ends in 0 → even
8. 14 → ends in 4 → even
9. 11 → ends in 1 → odd
10. 6 → ends in 6 → even
11. 9 → ends in 9 → odd
12. 4 → ends in 4 → even
13. 7 → ends in 7 → odd
14. 3 → ends in 3 → odd
15. 2 → ends in 2 → even
16. 1 → ends in 1 → odd

Now, let’s group them:

✔ Odd numbers (color red):
13, 5, 15, 11, 9, 7, 3, 1

✔ Even numbers (color green):
20, 8, 12, 10, 14, 6, 4, 2

Let me count to make sure I have 8 of each.

Odd: 13, 5, 15, 11, 9, 7, 3, 1 → that’s 8 numbers ✔️
Even: 20, 8, 12, 10, 14, 6, 4, 2 → that’s 8 numbers ✔️

Perfect! All 16 numbers are accounted for.

Final Answer:
- Color these numbers RED (odd): 1, 3, 5, 7, 9, 11, 13, 15
- Color these numbers GREEN (even): 2, 4, 6, 8, 10, 12, 14, 20
