Odd and Even Numbers Worksheets for Preschool and Kindergarten - Free Printable

Let’s go step by step to solve this worksheet.

We are asked to circle:
- EVEN numbers in the first section (problems 1–12)
- ODD numbers in the second section (problems 13–24)

Remember:
→ Even numbers end in 0, 2, 4, 6, or 8
→ Odd numbers end in 1, 3, 5, 7, or 9

Part 1: Circle the EVEN numbers

Problem 1: 15 5 11 17 → All end in odd digits → No even numbers
Problem 2: 12 15 2 18 → 12 (ends in 2), 2 (ends in 2), 18 (ends in 8) → Circle 12, 2, 18
Problem 3: 2 20 8 3 → 2, 20, 8 are even → Circle them; 3 is odd → skip
Problem 4: 6 5 8 16 → 6, 8, 16 are even → Circle them; 5 is odd → skip
Problem 5: 18 3 10 6 → 18, 10, 6 are even → Circle them; 3 is odd → skip
Problem 6: 1 16 18 8 → 16, 18, 8 are even → Circle them; 1 is odd → skip
Problem 7: 7 6 2 9 → 6, 2 are even → Circle them; 7 and 9 are odd → skip
Problem 8: 3 10 17 9 → Only 10 is even → Circle it
Problem 9: 14 3 11 4 → 14 and 4 are even → Circle them; 3 and 11 are odd → skip
Problem 10: 4 6 14 3 → 4, 6, 14 are even → Circle them; 3 is odd → skip
Problem 11: 1 9 18 14 → 18 and 14 are even → Circle them; 1 and 9 are odd → skip
Problem 12: 20 1 13 10 → 20 and 10 are even → Circle them; 1 and 13 are odd → skip

Part 2: Circle the ODD numbers

Problem 13: 9 19 17 3 → All end in odd digits → Circle all
Problem 14: 3 20 14 4 → Only 3 is odd → Circle it; others are even → skip
Problem 15: 10 15 7 16 → 15 and 7 are odd → Circle them; 10 and 16 are even → skip
Problem 16: 1 20 2 6 → Only 1 is odd → Circle it; others are even → skip
Problem 17: 3 1 8 6 → 3 and 1 are odd → Circle them; 8 and 6 are even → skip
Problem 18: 8 10 4 15 → Only 15 is odd → Circle it; others are even → skip
Problem 19: 8 19 16 3 → 19 and 3 are odd → Circle them; 8 and 16 are even → skip
Problem 20: 19 9 18 13 → 19, 9, 13 are odd → Circle them; 18 is even → skip
Problem 21: 17 4 9 10 → 17 and 9 are odd → Circle them; 4 and 10 are even → skip
Problem 22: 10 14 8 6 → All even → No odd numbers → Nothing to circle
Problem 23: 6 8 20 5 → Only 5 is odd → Circle it; others are even → skip
Problem 24: 7 4 3 16 → 7 and 3 are odd → Circle them; 4 and 16 are even → skip
