Lesson: Identifying Odd and Even Numbers by Pairing

In this lesson, we will learn how to identify whether a number up to 20 is even or odd by grouping objects in pairs and skip counting by 2s.

Sample Question Videos

Q1:

Here is a group of 9 people.

Can we divide the group into pairs so that everyone has a partner?

Q2:

A number is odd if we cannot split it into groups of two with nothing left over.

If we try to split these 9 squares into groups of 2, there is always one left over. So, 9 is odd.

Which of the following numbers is odd?

Q3:

Here are 57 dots. Is 57 even or odd?
