Pair the objects up. If none are left over, the number is even; one left over means odd. An even number splits into two equal parts: 14 = 7 + 7.
Watch for: Losing track of which objects are already paired. Looking at the tens digit instead of the ones digit. Splitting an even number into two unequal parts, like 14 = 6 + 8.
At home: Pair up socks, shoes or spoons and ask whether any are left over. Then say whether the number is odd or even.
