Identifying Even and Odd Numbers Through Visuals

This video tutorial teaches how to identify even and odd numbers. It explains that even numbers can be divided into two equal groups and can be expressed as a doubles fact, while odd numbers cannot. The tutorial includes problem-solving examples with teddy bears and squares to illustrate these concepts. Additionally, it demonstrates using skip counting on a number line to determine if a number is even.

What defines an even number?

• A number that can be divided into two groups with leftovers

• A number that cannot be divided into two equal groups
