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

• A number that can be divided into two equal groups without leftovers

• A number that is always greater than 10

What is a 'doubles fact'?

• Subtracting a number from itself

• A number added to itself

• A number that can be divided by two

• Adding any two numbers together

Why are even numbers easily divisible into two groups?

• Because they end in 2, 4, 6, 8, or 0

• Because they are always less than 100

• Because they can be written as a doubles fact

• Because they are larger than odd numbers

Why can't the number 9 be considered even?

• It is a prime number

• It cannot be divided into two equal groups without leftovers

• It can be written as a doubles fact

• It is greater than 8

How can you determine if a number is odd?

• It can be divided into two equal groups

• It is always less than 5

• It can be written as a doubles fact

• It cannot be written as a doubles fact

What makes a number odd?

• It ends in 1, 3, 5, 7, or 9

• It can be written as a doubles fact

• It can be divided into two equal groups without leftovers

• It is always smaller than an even number

In the teddy bear example, why is the total number considered odd?

• Because it cannot be written as a doubles fact

• Because there are 10 teddy bears

• Because it can be divided into two equal groups

• Because there are more than 5 teddy bears

What does the presence of 8 squares indicate about their number?

• They are odd

• They are prime

• They cannot form two equal groups

• They form a doubles fact

How does skip counting by twos help determine if a number is even?

• It shows if a number is greater than 10

• It only works for numbers less than 20

• It helps in adding numbers faster

• If you land on the number, it's even

What conclusion can be drawn if skip counting by twos lands on 16?

• 16 is odd

• 16 cannot be divided into two equal groups

• 16 is a prime number

• 16 is even
