About Even or Odd

Even or Odd is a fast, friendly way to lock in parity — the simple rule that even numbers end in 0, 2, 4, 6 or 8, and odd numbers end in 1, 3, 5, 7 or 9. The runner advances when the kid taps the right answer, and tries again on a wrong one without losing the level.

How it scales

• 1–10 for the very first attempts.
• 1–20, 1–50, 1–100 as confidence grows.
• 1–500 stretches kids into reading 3-digit numbers and noticing only the last digit matters.

Recommended for
