Odd and even: I can tell odd and even numbers apart.

1. Here are 6 socks.

   They make 3 pairs. None are left over.

   6 is even. Even numbers make pairs.

   Picture: 6 socks set out in pairs: 3 pairs, with none left over.

2. Here are 7 socks.

   3 pairs, and 1 sock is left over.

   7 is odd. Odd numbers have 1 left over.
