Odd and Even
Can we pair them up?
Odd and even is a statement about pairing: line the objects up in twos and see whether one is left over. Taught this way (around ages five to seven) it stays true for any quantity, instead of becoming a rule about the last digit that children cannot explain.

Even = everyone has a partner.
Six Yazies pair up perfectly. Every Yazie has a partner. Six is even. But seven Yazies? One Yazie is left alone. Seven is odd.
The rule
Even numbers end in 0, 2, 4, 6, or 8. Odd numbers end in 1, 3, 5, 7, or 9. Check the last digit.
What parents should watch for
- Learning "0, 2, 4, 6, 8 means even" as a digit rule with no idea what even means.
- Thinking odd means "strange" or "a small number".
- Assuming a large number must be even because it looks big.
- Forgetting that zero pairs up perfectly and is even.
