Is 11 odd or even

Step by step

The question

Question: is 11 odd or even?

Even means it makes pairs, with none left over.

Odd means one is left over.

1 Make pairs

Here are 11 dots in pairs.

A pair is 2.

Ring each pair.

One dot has no partner.

2 Odd or even

One is left over.

So 11 is odd.

3 Check

We count by 2s: 2, 4, 6, 8, 10, 12.

We jump over 11.

11 is not on the list.

Yes!

It works.

Let's look back.

First: make pairs.

Then: odd or even.

Last: check.
