Is 136 odd or even

Step by step

The question

Question: is 136 odd or even?

Even means it makes pairs, with none left over.

Odd means one is left over.

1 Look at the ones

136 is 130 and 6.

Every ten makes 5 pairs.

So 130 is all pairs.

Only the 6 ones are left to check.

2 Put the ones in pairs

Here are 6 dots in pairs.

A pair is 2.

Ring each pair.

Every dot has a partner.

3 Odd or even

None left over.

So 136 is even.

4 Check

We count by 2s from 130: 130, 132, 134, 136.

We land on 136.

Yes!

It works.

Let's look back.

First: look at the ones.

Then: put the ones in pairs.

Then: odd or even.

Last: check.
