Students will determine whether a group of up to 20 objects is odd or even by pairing the objects into groups of two. If all objects are paired with none left over, the number is even; if one remains, it is odd.

Even groups make complete pairs with none left.
Odd groups have one left without a partner.
Put 11 counters in pairs: 1 on top, 1 below. 5 pairs, and 1 counter has no partner. So 11 is odd.
An even number is a double: 10 = 5 + 5.
An odd number is a double and 1 more: 11 = 5 + 5 + 1.
Every even number splits into 2 equal rows.
Pair them up. All paired is even. 1 left over is odd.
Calling 11 even because 5 + 5 = 10 is close.
11 = 5 + 5 + 1. 1 is left over, so 11 is odd.
15 counters paired up make ___ pairs — 7. 15 = 7 + 7 + 1: 7 pairs, and 1 left over, so 15 is odd.
We found seven socks in the laundry. Is seven an even number or an odd number?
To find out, we pair them up — two socks at a time.
Two socks make our first pair.
Two more socks — that's pair number two.
And two more — that's pair number three.
But this last sock has no partner. It's all alone!
When one is left over after pairing, the number is odd.
So seven is odd. Nice pairing!
